Environmental Impacts: Organisms adapt to the environment

Ecological factors in the environment affect the life and distribution of organisms, such as the effect of temperature on the distribution of animals, polar bears. Effect of temperature on plants, coconut palms. These are environmental impact organisms.

Biological adaptation to the environment refers to the change of physiological structure or life distribution of organisms such as animals or plants due to external environmental conditions, for example, the cactus in the desert, its leaves become needle-shaped in order to adapt to the climate of the desert. In short, the environment affects the life and distribution of organisms, and organisms adapt and change the environment, and the two affect each other. I don't know how to ask again.

Let's start with the concept: Environmental impactOrganisms are passive changes due to changes in the environment.

Biological adaptation to the environment refers to the active change of organisms in order to adapt to changes in the environment.

That's a matter of priority. Let's take a look at a few examples to further understand.

1. The saving function of the camel's twin peaks is to survive in the arid desert.

In this example, the environment has not changed, while the camel has had a doublet for a long time, and the organism has changed actively, so it is the adaptation of the organism to the environment.

2. The birch inchworm is a creature that has changed its protective color due to changes in the environment.

The color of the trees does not change, and the birch inchworm changes to black or white on its own, so it is still the adaptation of the organism to the environment.

3. The south is rich in lychees and apples in the north, which is obviously an environmental impact organism.

There are often multiple-choice questions in biology questions to judge these things, and I summarized that generally there are different environments where the same organism is different is that the environment affects the organism, and the same environment and the same organism change is the adaptation of the organism to the environment.

The impact of living organisms on the environment is mainly divided into 3 categories, plants, animals, and microorganisms.

Plants can use carbon dioxide in the environment for photosynthesis, produce organic matter and oxygen, purify pollutants in the air, make the air fresh, and are of great significance for protecting the ecological environment.

Animals exhale carbon dioxide, inhale air, regulate the environment'Water vapor and temperature are also indispensable parts of the ecological environment.

Microorganisms can decompose organic matter in the environment, such as decomposing some animal and plant residues into inorganic matter to purify the environment, and some microorganisms such as nitrogen-fixing microorganisms can also convert inorganic matter into organic matter for plant growth, which is conducive to the circulation of substances.

The adaptation of organisms to the environment is both universal and relative. Because the environment in which organisms live is constantly changing, and the heredity of organisms is conserved and does not immediately change their heritability because of environmental changes, the formation of adaptation is the result of long-term natural selection.

The abiotic factors are mainly light, temperature, water, air, etc., and the ions are as follows:

Frost drought or winter drought occurs when the plant has water but cannot get it due to the low soil temperature, as winter occurs on the tundra, the roots of the plant are unable to absorb the water, while the leaves continue to lose water through transpiration, it can be said that the plant is relatively dehydrated. In both cases, more water is lost from the leaves and stems of the plant than is absorbed from the roots. Therefore, low temperatures can produce symptoms of drought.

The adaptation and impact of organisms on the environment are as follows: Plants can use carbon dioxide in the environment for photosynthesis, which plays an important role in protecting the ecological environment. Animals exhale carbon dioxide and inhale air, which regulates the temperature and moisture in the environment.

Every organism in nature has a certain degree of adaptability to the environment, which belongs to the universality of adaptation. The adaptation and impact of organisms on the environment are as follows: Plants can use carbon dioxide in the environment for photosynthesis, which plays an important role in protecting the ecological environment.

Animals exhale carbon dioxide and inhale air, which regulates the temperature and moisture in the environment. Every organism in nature has a certain degree of adaptability to the environment, which belongs to the universality of adaptation.

Organisms can only survive and reproduce by adapting to the environment, that is, every organism in nature has a certain adaptability to the environment. Different organisms have different effects on the environment, for example, plants can use carbon dioxide in the environment for photosynthesis, produce organic matter and oxygen, purify pollutants in the air, and make the air fresh.

1.Plants can use carbon dioxide in the environment for photosynthesis, produce organic matter and oxygen, purify pollutants in the air, make the air fresh, and have important significance for protecting the ecological environment.

2.Animals exhale carbon dioxide, inhale air, and regulate water vapor and temperature in the environment, which is also an indispensable part of the ecological environment.

3.Microorganisms can decompose organic matter in the environment, such as decomposing some animal and plant residues into inorganic matter to purify the environment, and some microorganisms such as nitrogen-fixing microorganisms can also convert inorganic matter into organic matter for plant growth, which is conducive to the circulation of matter.

Living organisms live in very complex environments and are constantly affected by various ecological factors in the environment. Organisms can only survive and reproduce by adapting to the environment, that is to say, every organism in Lupei nature has a certain adaptability to the environment, otherwise it would have been eliminated long ago, which is the universality of adaptation.

However, the adaptation of each organism to the environment is not an absolute and complete adaptation, but only a certain degree of adaptation, and the continuous change of environmental conditions has a great impact on the adaptability of organisms, which is the relativity of adaptation.

Regarding the adaptation of organisms to the environment is as follows:

In the interrelationship between organisms and the environment, on the one hand, the environment has an ecological role on organisms, which can affect and change the morphological structure and physiological and biochemical characteristics of organisms, on the other hand, organisms are also adaptable to the environment, and organisms adapt to changes in the external environment with their own variations.

The ecological adaptability of organisms is a manifestation of specific traits formed by organisms in order to adapt to the environment in the competition for survival. The comprehensive effect of organisms on various ecological factors in the environment finally shows the ecological adaptation of convergence and divergence.

The so-called convergence adaptation refers to the phenomenon that organisms that are quite distantly related to each other due to long-term living in the same environment through mutation, selection and adaptation have very similar phenomena in terms of organ morphology. The result is a strong consistency or similarity between different organisms in morphology, physiology, and development.

Divergent adaptation refers to the corresponding ecological variation in morphology and physiology produced by different individual groups of the same species due to the differences in distribution areas and the comprehensive influence of different environmental conditions for a long time.

The formation of ecotypes can be caused by geographical factors, biological factors, or human activities (such as introduction and domestication to expand the distribution area), and thus according to the type of dominant factors that form the ecotype.

Environmental impactsThe difference between organisms and organisms adapting to the environment is that the meaning of the two is different. Environmental impact organisms refer to: organisms are passively changed due to changes in the environment; Biological adaptation refers to:

Organisms take the initiative to change in order to adapt to the changes in the environment, which is the problem of primary and secondary Lu Yu.

Characteristics of biological adaptation to the environment:

The property of the biological organism to survive by adapting to changes in the environment on its own. It is a phenomenon that is unique to living organisms and is defined from an evolutionary point of view as "the phenomenon of surviving and reproducing offspring", in which organisms can change their structure or function to adapt to the environment. The adaptation of organisms to the environment can be divided into two types:

Phenotypic adaptation and genotypic adaptation.

Effects of the environment on living things:

The abiotic factors that affect the life of living things are related to temperature, water, air, etc., without light, green plants cannot carry out photosynthesis. Light not only affects the physiological changes and width of plants, but also affects the behavior, growth and development of animals.

If there is no water, living things cannot live, and water can affect not only the distribution of plants, but also the survival of living things. Without air, living things can't breathe. There are very few biological species in the cold north and south poles, while there are many biological species and large numbers in temperate and tropical regions, which indicates that temperature is also one of the factors affecting the distribution of organisms.

Biotic factors are other organisms that affect the life of living beings, and in nature, every living thing is affected by other organisms around it. The relationship between organisms is divided into intraspecific relationships and interspecific relationships. Predator relationships, competitive relationships, intraspecific struggles, etc. <>

The adaptation of organisms to their environment is universal. Every living organism now has a morphological structure, physiological characteristics or behavior that is adapted to the environment. This is the universality of the adaptation of organisms to the environment.

The materials and energy needed to sustain the life activities of living organisms must be obtained from the environment.

The environment has many impacts on living things. Organisms can only survive if they adapt to their environment. Organisms are able to influence the environment as well as adapting to it.

For example, transpiration from forests can increase the humidity of the air, which in turn affects rainfall. Plants such as cedar can absorb toxic gases, which can purify the air; Rats have a destructive effect on crops, forests and grasslands; Earthworms move in the soil, which can loosen the soil, improve the soil's aeration and water absorption capacity, and its excrement can also increase the fertility of the soil. It can be seen that organisms and the environment are mutually influential, and they are an inseparable and unified whole.
