In an ecosystem, the primary relationship between various organisms is relationship

This relationship can be a food web, or an ecological web.

The basis of this relationship is green aerobic respiration plants, which absorb carbon dioxide and use inorganic matter to synthesize the organic matter they need and release oxygen. Oxygen is essential for animal survival. This is followed by herbivores, which are large in number and who specialize in eating greenery.

Herbivores are followed by carnivores, which are significantly less numerous, and they hunt herbivores.

Carnivores are at the top of the food chain. The animal's manure can then be used as nutrients for green plants, helping the plants grow.

The carcass of the carnivores is then broken down by bacteria, which reduce pollution to the environment, and bacteria, as a special organism, also play a role in this cycle.

That's how the ecosystem goes in circles. To put it bluntly, it is the relationship between eating and being eaten.

Ability flow, material flow, gene flow.

Ability flow: The process by which the energy of one organism is transferred to the next organism during the process of eating and being eaten.

Material flow: the process by which water, fat, starch, k, na, ca, and various elements change from one individual to another, from one state to another.

Gene flow (between individuals of the same species): For example, a certain monkey grown up in Sichuan and the same species grown up in Yunnan are the same species, but there are still significant genetic differences. When the Sichuan monkeys ran to Yunnan and got married and had children, they brought some genes from the Sichuan monkeys to Yunnan, which is gene flow.

Predation relates to the flow of energy and the cycle of matter.

To sum up, the relationship between food, the flow of energy and the cycle of matter.

Energy flows, matter circulates.

The relationships between various organisms in an ecosystem are diverse, involving nutrition, predation, competition, symbiosis, etc. Here are some common biological relationships:

1. Predatory relationship.

Some animals obtain their nutrition by preying on other animals, such as lions preying on wild antelopes. The relationship between predator and predator is both competitive and dependent.

2. Competition.

Organisms in the same habitat may compete with each other due to limited resources and habitats. For example, two male zebras compete for the right to mate with the same female. This relationship has an impact on both survival and reproduction.

3. Symbiotic relationship.

Organisms between different species can benefit together through a symbiotic relationship. For example, there is a symbiotic relationship between the beak tree and the beak bird, which can use the flowers on the beak tree for food and pollinate the beak tree.

4. Reciprocal symbiotic relationship.

The two creatures benefit from each other by cooperating with each other. For example, there is a relationship between bees and flowers, where bees can collect pollen from flowers for pollination, and flowers provide honey juice and pollen.

5. Parasitic relationship.

Some organisms can get their nutrients from other organisms, such as parasites that parasitize their hosts. This relationship can have a negative impact on the health of the host.

6. Coexistence.

Organisms in the same habitat can sometimes share productive resources and space through coexistence. Organisms of different species can live together without interfering with each other, such as various plants and animals in the forest.

In short, the organisms in the ecosystem are interdependent and influence each other, forming a complex network of biological relationships. These relationships have both synergistic aspects and contentious and pressures, and are important forces for the evolution and development of ecosystems.

There can be many kinds of relationships between organisms in an ecosystem, such as competition, reciprocal symbiosis, predation, etc. The following is an example of competition and predation to illustrate the characteristics of the relationship between two organisms in an ecosystem.

1. Competition.

Competitive relationship refers to the relationship between different species or the same species of organisms to compete for limited resources. This relationship is mutually negative, because the same resource is shared by multiple organisms, which will hinder each other, leading to more intense competition.

For example, two plants on the grassland need water, nutrients, sunlight and other resources to grow and reproduce, and there is a competition between them. If one of these plants is able to use these resources more efficiently, they will grow faster and occupy a larger ecological niche to win the competition.

2. Predatory relationship.

A predatory relationship refers to a relationship in an ecosystem in which one organism feeds on another. This relationship is interdependent, because the survival of one directly affects the survival of the other.

For example, lions on the grasslands hunt antelopes for food, and there is a predatory relationship between the two creatures. If the antelope population is too small, the lion will face a shortage of food, which may cause starvation and death. Conversely, if there are too many lions, they will overkill the antelope, resulting in a declining antelope population or even endangerment.

In short, there can be many kinds of relationships between organisms in an ecosystem, and the characteristics of different relationships are different. The relationship between different organisms establishes their position and role in the ecosystem, and this intertwined relationship network is an important guarantee for the ecological balance of the ecosystem.

The ecosystem is composed of biotic and abiotic components Abiotic components include sunlight, air, water, temperature and soil, etc. They provide energy, nutrition and living space for living organisms Biotic components include all organisms in the ecosystem According to the way of obtaining nutrients and energy, biotic components can be divided into producers, consumers and decomposers of which producers mainly refer to green plants; Consumers include a variety of animals; Therefore, an ecosystem is composed of biotic and abiotic parts

Therefore, the answer is: non-raw socks and jujube early parts

The relationships between organisms include: intraspecific relationships and interspecific relationships Intraspecific relationships are further divided into intraspecific mutual assistance (cooperative relations) and intraspecific competition; There are several ways of symbiosis, parasitism, predation, and interspecific competition in the interspecific relationship of a complete ecosystem.

Includes the biotic and abiotic parts, while the biotic part in turn includes producers (plants), consumers (animals) and decomposers (bacteria, fungi) Plants are producers and can photosynthesize.

Making organic matter Animals are consumers and cannot photosynthesize to make organic matter on their own, they feed directly or indirectly on plants Consumers eat producers, producers are eaten by consumers, and the relationship between producers and consumers between eating and being eaten, i.e., food relations, constitutes the food chain.

The food chain is intertwined with each other to form a food web The remains of animals and plants after death are broken down into carbon dioxide by bacteria and fungi.

and water, inorganic salts, etc., carbon dioxide, water, and inorganic salts are used by plants Therefore, various organisms in the ecosystem are connected to each other through various relationships, the most important of which is the food relationship

Therefore, b

Decomposers, consumers, producers.

Answer]: B In a certain range of space and time, a unified whole that interacts with various organisms through energy flow and material circulation between various organisms and their inorganic environment, also known as "ecosystem", is a balanced system that interacts with each other and is constantly moving.

Answer]: B Ecosystem has the following characteristics: (1) Ecosystem is a major structural and functional unit in ecology, which belongs to the highest level of ecological research.

2) The ecosystem has the ability to self-regulate. The more complex the structure and the greater the number of species, the stronger the ability to self-regulate the plum joints. (3) Energy flow and material circulation are the two major functions of the ecosystem.

4) The number of trophic level fluctuations in the ecosystem is limited by the fixed energy value of the producer and the energy loss in the process of energy flow, which is generally not more than 5 6. (5) The ecosystem is a dynamic system, which has to go through a developmental process from simple to complex, from immature to mature.

Cacti in CB are born in the desert.

Cheetah in a grassland ecosystem.

A test question analysis: sorghum and soybean can be planted at the same time in farmland with suitable climate; Cheetahs mainly live in grassland ecosystems, and giant pandas live in forest ecosystems rich in bamboo. Calamus is a freshwater plant, whereas nori lives in the ocean; Red-crowned cranes live in swamps, shallows, etc., while cacti live in dry deserts, so they can live in the same ecosystem
