What is the difference between biosphere, community, food chain and ecosystem?

In simple terms, the biosphere is all matter and living things, both organic and inorganic, from how many meters below the ground to how many meters in the sky. A community is a group of organisms (various organisms) that live within a certain range, and are just living organisms. The food chain is the relationship between organisms that prey on each other, and of course a community contains a food chain.

There are many kinds of ecosystems, such as forests, grasslands and other ecosystems, and these ecosystems include multiple communities. And the biosphere is an ecosystem, of course, the largest ecosystem. In short, their relationship is the biosphere = ecosystem biome food chain.

Food chain: Generally speaking, it is a sequence in which various organisms closely connect this organism with that organism through a series of eat-and-eat relationships, and the organisms are linked to each other by food-nutrient relationships, which is called the food chain in ecology.

Community: refers to the regular combination of multiple biological populations with direct or indirect relationships, with complex interspecific relationships. For example, all living things in a field are a community.

Ecosystem: A unified whole formed by the interaction of a biological community with its inorganic environment, called an ecosystem. For example, the organisms of a piece of farmland and its inorganic environment constitute an ecosystem.

Biosphere: The sum total of all living things on Earth and their inorganic environment, constituting the largest ecosystem on Earth Biosphere.

A community is the whole living thing in an area.

Ecosystem is a community + inorganic environment.

The biosphere is the largest ecosystem on Earth.

The food chain is the trophic structure of the ecosystem, with only producers and consumers, starting from both.

It's the producer, pointing an arrow from the predator to the ** eater. Such as leafhoppers and praying mantises. Yellow Sparrow.

Start at the bottom, count how many there are, and then count up each one.

1. The food chain is also known as the "nutrition chain". In order to maintain their own life activities, various organisms in the ecosystem must feed on other organisms. This feeding relationship is actually the relationship between solar energy from one organism to another, that is, the flow and conversion of material energy through the food chain.

2. A food chain generally includes 3-5 links: a plant, an animal that feeds on plants and one or more carnivores. The number of organisms at different points in the food chain is relatively constant in order to maintain a natural balance.

The chemical energy stored in the organic matter in the ecosystem is transmitted layer by layer in the ecosystem, and in layman's terms, it is a series of organisms that closely link this organism with that organism through a series of eating and being eaten, and the sequence in which this organism is closely linked to each other by the relationship between food and nutrition, just like a chain, one link after another, which is called the chain of food wide residue in ecology. According to the relationship between organisms, the food chain can be divided into predatory food chain, carrion food chain (Shen Qin crept food chain), and parasitic food chain. Within an ecosystem, a connection between various organisms due to food is called the food chain.

There are many kinds of organisms in the ecosystem, and they play different roles in the ecosystem, and according to the role they play in the movement of energy and matter, they can be classified into three categories: producers, consumers and decomposers. Producers are mainly green plants, autotrophs that can make nutrients from inorganic matter, this function is photosynthesis, and also includes some chemobacteria (such as nitrifying bacteria), they can also synthesize organic matter from inorganic matter, and the role of producers in the ecosystem is to carry out primary production or primary production, so they are primary producers or primary producers, and the biomass they produce is called primary production or primary production. The activity of the producer is to obtain carbon dioxide and water from the environment and synthesize carbohydrates (mainly glucose) under the action of sunlight or chemical energy.

Therefore, only through the producer can solar radiation energy be continuously input into the ecosystem into chemical power, that is, bioenergy, which becomes the only energy source in the life activities of consumers and decomposers.

The biosphere is the largest ecosystem on Earth.

But ecosystems can be divided into many small areas, it can be an ocean, a forest, a pond, and even the smallest ecosystem can be an "eco-ball" or "eco-bottle".

Ecosystem: Biome.

The whole formed by interacting with its inorganic environment, its scope can be large or small, an ecological bottle, a farmland, a pond, a forest, can be called an ecosystem, and the biosphere is also an ecosystem, but the scope of the biosphere is very large. The biosphere is the general term for all living things on the earth and their inorganic environment, and it is the largest ecosystem on the earth.

It includes the atmosphere.

The lower layer, the upper layer of the lithosphere, the entire pedosphere and hydrosphere. However, most of the organisms are concentrated at the junction of the atmosphere, hydrosphere, lithosphere, and pedosphere, which is the core of the biosphere, from 100 meters above the surface to 100 meters below the water.

The biosphere is also an ecosystem, except that it refers to the integrated whole of all the ecosystems on the earth, and is an outer sphere of the earth, which covers about 10 kilometers vertically above and below sea level. It includes air, land, lithosphere, and water on Earth where life exists and is changed and transformed by life processes.

Naturally, there will be.

The biosphere is the largest ecosystem".

If you want to talk about the difference, then the biosphere is an ecosystem, and the ecosystem is not necessarily the biosphere, and all ecosystems on the earth in general can generally be said to be part of the biosphere.

Because: the biosphere refers to the horizon as a reference, up to 10 km of the atmosphere, down to 10 km of the ocean, and is composed of all parts of the ocean. These include the atmosphere, lithosphere, and oceanosphere.

As the largest ecosystem on Earth, the biosphere is also encompassing a variety of ecosystems, to be precise, composed of multiple ecosystems. It is composed of two artificial ecosystems: urban ecosystem and farmland ecosystem. Natural ecosystems include forest ecosystems, grassland ecosystems, lake (freshwater) ecosystems, desert ecosystems, savanna ecosystems, mountain ecosystems, wetland ecosystems, marine ecosystems, and so on.

The difference between ecosystem and biosphere is that the scope is different and the concept is different, the biosphere refers to the general term of all living things on the earth and their living environment, and the ecosystem refers to the unified whole composed of organisms and the environment. The extent of the biosphere is larger than that of ecosystems, which can be large or small. ecosystems and biospheres'The difference lies in the different scopes and concepts, the biosphere refers to the general term for all organisms on the earth and their living environment, and the ecosystem refers to the unified whole composed of organisms and the environment.

The extent of the biosphere is larger than that of ecosystems, which can be large or small.
