How to distinguish between the two concepts of lifestyle and growth ? Content of pollution ecolog

There is some controversy between the concept of growth type and life style. According to page 99 of "Vegetation Ecology" edited by Song Yongchang, life form refers to a morphological manifestation formed by the long-term adaptation of organisms to changes in the environment and its rhythm; Growth type refers to the morphological characteristics of the general structure of an organism.

In the book "Vegetation of China", trees, shrubs and grasses are used as life forms. A similar concept to both is ecotype.

I agree with the following definition:

Life form - is the type of life and appearance of plants that are manifested in their life and appearance due to their long-term adaptation to the comprehensive conditions of the environment. It is a reflection of a certain degree of unity between the plant body and the environment. Life forms have nothing to do with taxonomic units in taxonomy. More typical examples are convergent evolution.

Growth type refers to the morphologically comparable type that has evolved into a group of taxa that are often unrelated in kinship, and which is an adaptation to a specific life style in a specific habitat. I thought it could be used in a certain way to live in a certain situation, but it was more focused on the form aspect.

Ecotype - is the variability and differentiation of individual populations of the same plant due to long-term adaptation to different environments, which are stable and hereditary in morphological, ecological and physiological characteristics. More typical such as divergent evolution.

In the process of long-term adaptation to the environment, a certain number of living plants are produced with different ecological functions, some of the ecology adapts to different single factors (light, temperature, water, minerals), while some are complex factors (wind, altitude of climate), to adapt to different environmental ecological species special habitat genotype or genotype formation reaction products occur is a subunit ecological species. Life type refers to the way in which the evolution of an organism adapts to the environment, and the corresponding segmentation of the morphological type manifests a specific appearance, structure, size, behavior and life, which is called a life form. A life form is a long-term adaptation of an organism to environmental conditions.

a. There are 9 E. coli per milliliter of river water, which reflects the quantitative characteristics of the population (population density), and a is false;

b. The population of rats on the farm declined, but the rats did not die out, so the species diversity of the farm did not decline, B is false;

c. The vegetation types in different vertical zones in the Hengduan Mountains of Southwest China are different, which is caused by the different temperature and other factors in different vertical zones.

d. The more species of organisms, the more complex their trophic structure, and the higher the stability of resistance, so scientifically increasing the species of organisms to the ecosystem can improve the stability of the system's resistance, d is correct

Therefore, d

Differences: Environmental factors generally refer to abiotic factors, climate, water sources, etc.; However, in the field of animal ecology, vegetation can also be used as an environmental factor. Ecological factors are all the influencing factors related to the ecological field, the main category is the organism-environment, the organism-organism interaction, who is the subject of research, and the various factors related to it are all ecological factors.

Ecological factors refer to various environmental factors that have an impact on living organisms. It often acts directly on individuals and groups, mainly affecting individual survival and reproduction, population distribution and quantity, community structure and function, etc. Each ecological factor not only acts on its own, but also interacts with each other, being influenced by other factors around it, which in turn affects other factors.

Ecological factors are divided into three categories: abiotic factors, biotic factors, and anthropogenic factors. Abiotic factors mainly include climatic factors (such as light, temperature, etc.), moisture factors and soil factors. Biological factors mainly refer to the mechanical interaction between plants, symbiosis, parasitism, epiphyticism, animal feeding, pollination and trampling of plants.

Human factors include human reclamation, grazing and logging, environmental pollution, etc., which is a very special type of factors.

Among the various ecological factors, not all of them are necessary for the growth of plants. We call the factors necessary for plant growth as survival conditions, that is, plants cannot grow without them. For green plants, these factors are oxygen, carbon dioxide, light, heat, water, and inorganic salts.

When there is an abnormality in a certain living conditions in the environment, it will inhibit plant life activities or threaten plant survival, this phenomenon is called environmental stress. Phenomena such as animal feeding, parasitism, wind damage, fire, and soil erosion can partially or completely destroy the products of plant life activities, which is known as disturbance.

Life Forms Terrestrial plants can be broadly divided into high bud plants, aboveground bud plants, ground bud plants, underground bud plants, and annual plants.

Growth: Dendriform, vine, shrub, epiphyte, herbaceous.

The life type is already harmonious, but the growth type is not.

Explanation of the ecological environment.

Biology and the sum of all external conditions that affect the survival and development of living beings. It is composed of many ecological factors, including abiotic factors such as light, temperature, moisture, atmosphere, soil and inorganic salts, and biological factors such as plants, animals and microorganisms. In nature, ecological factors are interconnected, mutually influencing, and working together to act on living things.

The explanation of the word decomposition ecology refers to the state of survival and development of organisms in a certain natural environment, and also refers to the physiological characteristics and living habits of organisms to assist farmers to change their ecological and technical explanations of plants. show a beautiful posture .

The New Tang Dynasty Book: The Biography of Wang Ning: "When the environment of Jiangnan was a pirate area, the condensation was based on quarrying with crossbows, Zhang was suspicious, and sent Ma Ying to relieve the siege of Hezhou. Song Hongmai.

Ecological environment is not equal to the environment in the usual sense, it can be understood as the relationship between the state of organisms and the environment, which refers to the sum of all external conditions in the ecosystem except for human populations and relative to the biological system, including various elements that can directly or indirectly affect the survival and development of organisms in a specific space, and emphasizes the complex of all environmental conditions that affect the state of organisms within the boundaries of the ecosystem.

The ecological environment of human beings is a human-centered ecological environment. The human ecological environment is condensed and trapped by the interaction of natural and social factors, and is a unity composed of the natural ecological environment and the social ecological environment.

4. Overview of Environmental Pollution

Under the trend of increasing environmental awareness, real estate brokerage activities should also involve awareness and understanding of environmental pollution. Awareness and understanding of environmental pollution should include the concept, types, hazards, pollutants and sources of environmental pollution, as well as the prevention and control of environmental pollution.

1) The concept of environmental pollution.

Environmental pollution refers to the phenomenon that harmful substances or factors enter the environment and diffuse, migrate and transform in the environment, causing changes in the structure and function of the environmental system, and having a negative impact on the survival and development of human beings and other organisms.

2) Types of environmental pollution.

There are different types of environmental pollution, and there are different ways to divide it according to different purposes and angles. According to environmental factors, it can be divided into air pollution, water pollution, soil pollution, etc.; According to the nature of pollutants, they can be divided into physical pollution (such as sound, light, heat, radiation, etc.), chemical pollution (such as inorganic matter, organic matter), biological pollution (such as mold, bacteria, virus, etc.); According to the form of pollutants, it can be divided into exhaust gas pollution, wastewater pollution, noise pollution, solid waste pollution, radiation pollution, etc.; According to the causes of pollution, it can be divided into industrial pollution, traffic pollution, agricultural pollution, life pollution, etc.; According to the polluted space, it can be divided into indoor pollution and outdoor pollution; According to the scope of pollutant distribution, it can be divided into global pollution, regional pollution, local pollution, etc.

According to the type of organism studied:There are microbial ecology, plant ecology, animal ecology, human ecology, etc.; It can also be subdivided, such as insect ecology, fish ecology, etc. According to the structural hierarchy of biological systems:

There are individual ecology, population ecology, community ecology, ecosystem ecology, etc.

There are many more definitions of ecology:

Ecology is the science of how living things, including animals and plants, live and why they live the way they live. (Elton, 1927).

Ecology is the science of studying the distribution and abundance of organisms. （andrenathes,1954）

Ecology is the study of the structure and function of ecosystems. （，1956）

Bioscience is the study of the interaction between living systems and their mechanisms. (Ma Shijun, 1980).

Ecology is the science that comprehensively studies organisms, the physical environment, and human society. （，1997）

Both biotic and abiotic factors are included.

Abiotic factors mainly include light, water, humidity, and temperature.

Biological factors: All other organisms, including organisms of the same species and different species, that affect the height of the living order of a certain organism.

The common relationships between organisms and the first ruler of organisms are: predatory relationship, competitive relationship, cooperative relationship, parasitic relationship, etc.

Ecological factors are divided into biotic and abiotic factors. Ecological factors refer to environmental factors in the environment that have a direct or indirect impact on the growth, development, reproduction, behavior and distribution of organisms, such as sunlight, temperature, food, oxygen, carbon dioxide and other related organisms.

Ecological factors can also be regarded as environmental factors that act on organisms, but factors such as altitude and depth of water do not belong to ecological factors, because their role is indirectly reflected through ecological factors such as temperature, light, and air pressure, and they themselves have no direct impact on organisms.

Both biotic and abiotic factors are included. Abiotic factors mainly include biological factors such as light, water, humidity and temperature: all other organisms that affect the life of an individual of a certain species, including organisms of the same species and different species.

The common relationships between organisms are: predatory relationship, competitive relationship, cooperative relationship, parasitic relationship, etc.
