What kind of ecosystems are producers and consumers in an inverted pyramid?

It should be urban and farmland ecosystems.

In natural ecosystems, because the previous trophic level has to feed the next trophic level, there is a loss in the process of energy transfer. Therefore, the energy should follow the principle of less and less, and the energy of the previous trophic level must be more than the next trophic level in order to feed the next level of organisms, so there will be no inverted pyramid shape.

In artificial conditions, such as farmed pond ecosystems, the energy required by the consumer, the fish, comes mainly from artificially added feed rather than from the producer. So, even if the producer does not have much energy, the consumer fish can still survive. That is, the number of consumers is more than the producer, and the number of the upper level is smaller than the next level, and an inverted pyramid appears.

For example, a big tree lives on a group of birds and some insects, insects eat the branches and leaves of the tree, birds eat insects, which forms a food chain, in terms of quantity, the number of producer trees is at least one, and there are many consumers of birds and insects, which is the so-called inverted pyramid structure, and the other is farmland, in fact, there are several, all of which are relatively detailed small ecosystems.

The impression is that of urban ecosystems and farmland ecosystems, because these two types are artificial, and there are relatively few types of producers, and the main consumer group, people, also derives material and energy from other ecosystems.

The ecosystem is composed of biotic and abiotic components Abiotic components include sunlight, air, water, and soil They provide energy, nutrients, 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; Decomposers mainly refer to bacteria, fungi and other microorganisms that live in saprophytics

So the answer is: green plants; various animals; Bacteria; Fungi.

Test Center:

Analysis: From what we have learned, we know that a complete ecosystem is composed of biotic and abiotic parts, and the biotic parts include producers (green plants), consumers (animals) and decomposers (bacteria, fungi); The abiotic part refers to factors such as light, temperature, and water that affect the survival of living things

In addition to the biological part composed of producers, consumers, and decomposers, the ecosystem also has an abiotic part, mainly referring to air, light, water, temperature, etc

So the answer is:

Comment: It is important to know that ecosystems are made up of biotic and abiotic parts

The composition of the ecosystem (teaching by knowledge points) - the composition of the ecosystem.

No, there are also abiotic substances such as sunlight, water, inorganic salts, ......

Answer]: The ecological pyramid arranges and draws the individual number, biomass or energy of organisms at each trophic level in the ecosystem in the order of trophic levels, which resembles a pyramid, so it is called an ecological pyramid or ecological cone. It refers to a quantitative relationship between various trophic levels, which can be in the form of biomass units, energy units or individual quantity units, and the ecological pyramids composed of these units are called biomass pyramids, energy pyramids and quantitative pyramids, respectively.

There are three types of so-called "ecological pyramids"; Biomass pyramids, energy pyramids, and quantity pyramids. Ecological pyramid refers to the division of ecosystems into trophic levels and the arrangement of these trophic levels in a pyramidal pattern.

Advantages and disadvantages: 1. Quantity pyramid.

The number of individuals at each trophic level in an ecosystem at a given time. Meaning of each step: Indicates the number of individual organisms at each trophic level.

Inversion is often occurring. As the trophic level increases, the energy becomes less and less, and the size of the animal generally increases, so the number of living individuals decreases.

2. Biomass pyramid.

The weight relationship of organisms at various trophic levels in an ecosystem at a given time. Energy exists in the form of matter, so the biomass (the total mass of living organisms) at each trophic level represents the energy value to a certain extent, and in this sense, the shape of the biomass pyramid is generally similar to the shape of the energy pyramid. The special shape of the cone of the number of creatures:

For example, in marine ecosystems, producer phytoplankton are small, short-lived, and constantly eaten by zooplankton, so the simple biomass of phytoplankton surveyed at a given time may be lower than that of its predators, but this does not mean that less energy flows through the producers than through zooplankton.

3. Energy pyramid.

The amount of energy assimilated by trophic levels in an ecosystem over a period of time. The lower the trophic level, the more energy it holds; Conversely, the higher the trophic level, the less energy it occupies. Therefore, the base of the energy pyramid is the largest, and the higher it goes, the smaller it becomes.

The energy pyramid is never inverted.

Urban ecosystems.

The producers are mainly green trees and ornamental flowers, the consumers are mainly people and pets and a small number of urban wildlife (rats, birds and some insects) The decomposers are mainly bacteria and some fungi.

P.S. Let's take a look: in urban ecosystems, the number of producers is the smallest, the number of consumers is the largest, and the number of decompositions is relatively small. This is why the urban ecosystem needs to introduce a lot of food from the outside ecosystem, and it will produce a lot of waste, because the number of its own decomposers is not enough to completely decompose the waste it produces, so he will discharge the waste waste to other ecosystems.

Producers, consumers, decomposers, and abiotic components.

Wrong. Question analysis: The ecosystem includes biological components and abiotic components, biological components include producers, consumers and decomposers, producers mainly refer to green plants, which can produce organic matter through photosynthesis to provide material and energy for themselves and other organisms in the biosphere, consumers mainly refer to various animals, animals directly or indirectly feed on plants, are consumers, and play an important role in promoting the material cycle in the biosphere, decomposers refer to bacteria and fungi and other saprophytic microorganisms, They can decompose the organic matter in the remains of animals and plants into inorganic matter and return it to the inorganic environment, which promotes the circulation of matter, so the answer to this question is b.

Comments: This question is a basic knowledge question, which is easy, and you can be proficient in the composition and role of the ecosystem, and you can answer this question.

Test Point: Analysis: From what we have learned, we can know:

A complete ecosystem is made up of biotic and abiotic parts, while the biotic part includes producers (green plants), consumers (animals), and decomposers (bacteria, fungi); The abiotic part refers to factors such as light, temperature, and water that affect the survival of living things

In addition to the biological part composed of producers, consumers, and decomposers, the ecosystem also has an abiotic part, mainly referring to air, light, water, temperature, etc

So the answer is:

Comment: It is important to know that ecosystems are made up of biotic and abiotic parts

The ecosystem is composed of two parts: abiotic components and biotic components The biotic components include all the organisms in the ecosystem According to the way of obtaining nutrients and energy, the biological components can be divided into producers, consumers, and decomposers where producers refer to green plants They use light energy to make organic matter into organic matter through photosynthesis, and convert light energy into chemical energy and store it in organic matter; Consumers refer to all kinds of animals that depend directly or indirectly on the organic matter produced by green plants Decomposers refer to bacteria, fungi and other saprophytic microorganisms that decompose the organic matter contained in animal and plant residues into simple inorganic matter and return it to the inorganic environment, which promotes the circulation of substances The statement in the stem lacks abiotic components

So the answer is:

Plants and animals.

This question examines the composition of ecosystems, which refers to the unified whole formed by organisms and the environment within a certain geo-return area

Solution: The ecosystem is composed of biotic components and abiotic components Abiotic components include sunlight, air, water and soil They provide energy, nutrients 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; Decomposers mainly refer to bacteria, fungi and other microorganisms that live in saprophytics

So the answer is: plants; Animal;

The composition of the ecosystem is the focus of the examination, which mostly appears in the form of multiple-choice questions, material questions, and fill-in-the-blank questions, and the difficulty is average
