In the biosphere, you think that kind of organism is an indispensable ingredient

Cyanobacteria, the earth's atmosphere is all modified by it, and even now it produces the highest amount of oxygen because of the large amount.

Well, it should all be, no one can do it without it

A: According to the Pin Chain Question, green plants are the most basic and important biological components of the biosphere. Green plants are producers that provide food for the entire ecosystem, and without plants, animals and the like cannot survive, so plants are the most basic and important biological components in the biosphere

Greenery is the most basic and important biological component of the biosphere.

An organism is an individual, not a component, in an ecosystem. Ecosystems are an artificially defined field of study.

An ingredient is a certain substance that an individual is made up of, and it can be said that a biological individual is made up of various components.

But it cannot be said that ecosystems are made up of a variety of various components.

No, unicellular organisms are both at the cellular level and at the individual level.

The largest proportion of organic matter elements in the biosphere is ().

a.Nitrogen. b.Oxygen.

c.Hydrogen. d.Carbon.

The old man answered this group: c

Microorganisms refer to the individual tiny, simple structure of the lower organisms, microorganisms in addition to the commonality of organisms, also have their unique characteristics: one is a wide variety, the other is widely distributed, more than 100,000 kinds of microorganisms have been discovered, new species continue to be discovered It can be said that microorganisms are everywhere, everywhere, glaciers, hot springs, craters and other extreme environments have traces of microorganisms

So the answer is: microorganisms.

The size of the biosphere is usually expressed by the main components that make up the organism, the slip width is the () on the blot.

a.Total nitrogen.

b.Oxygen content.

c.Amount of organic carbon.

d.Water. Correct withered and answered: c

a. In the ecosystem, plants can photosynthesize to produce organic matter, for producers, animals directly or indirectly feed on plants, for consumers, bacteria and fungi rely on decomposing the remains of animals and plants, for decomposers Theoretically, there can be no consumers, and the essential biological components in the ecosystem are producers and decomposers But in the actual ecosystem, there are basically producers, consumers and decomposers It does not meet the topic

b. The ecosystem has a strong ability to self-regulate, but its ability to regulate has a certain limit, and if the damage exceeds its ability to regulate, the ecological balance will also be broken

c. The ecosystem has a strong ability to self-regulate, and the extinction of a species will not lose the balance of the entire ecosystem

d. Toxic substances cannot be decomposed and discharged in the body of living organisms, and can only gradually accumulate with the transmission of the food chain, which is in line with the topic

Therefore, d

Answer C Analysis: This question examines the role of producers, consumers, and decomposers

Answer: Producers can synthesize inorganic matter from the environment into organic matter that stores energy; Consumers feed directly or indirectly on producers, converting a part of the producer's organic matter and energy into a part of their own matter and energy; The decomposer can decompose the organic matter in the remains or relics of animals and plants into inorganic matter, so that the substances of the ecosystem can follow the silver cycle; If there is no producer, it is impossible to synthesize a machine that stores energy; If there are no decomposers, the remains of plants and animals will pile up, and the materials of the ecosystem cannot be recycled Therefore, producers and decomposers are indispensable biological components of the ecosystem Therefore, c is in line with the topic

Selection: C Comment: If the biological components of an ecosystem are only producers and decomposers, the ecological balance can still be maintained

I would like to add that if you are a high school student, you can turn to the compulsory one P16

In addition, there are differences between different organisms, and the same is true. Different organisms selectively absorb substances containing different elements from the outside according to their own needs.

There is both uniformity and difference between them in terms of chemical composition. The types of substances are roughly the same from one organism to another, but the content of each substance varies greatly. Between organisms and the environment, all biological elements can be found in the environment, but the content of each element is different.
