EcosystemAn Ecosystem is a community of living organisms (plants, animals and microbes) in conjunction with the non-living components of their environment (things like air, water and mineral soil), interacting as a system. These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows. As ecosystems are defined by the network of interactions among organisms, and between organisms and their environment, they can be of any size but usually encompass specific, limited spaces (although some scientists say that the entire planet is an ecosystem).

What Is A Population?A population is one species living in a specific area.

For example, all foxes living in an area form a population.

Another example, all dandelions growing in an area form another population.

What Is A Community? A community is formed from all living populations found in an area.

All the foxes, dandelions, grasshoppers, snakes, hawks, deer, and skunks living in one area each form their individual populations, but together make up a community

Biological Components of Ecosystems

Biotic Components

The living parts of an ecosystem.

They include animals, plants, fungus, protists(amoeba), and

bacteria.

Abiotic Components

The nonliving parts of an ecosystem.

The abiotic factors of an ecosystem can be listed through SWATS: Soil, Water, Air, Temperature, and Sunlight.

In biology, abiotic factors can include soil acidity, light, radiation, temperature, water, atmospheric gases, and soil. The macroscopic climate often influences each of the above. Pressure and sound waves may also be considered in the context of marine or sub-terrestrial environments.

Food Chains

The producers, consumers, and decomposers of each ecosystem

make up a food chain.

There are many food chains in an ecosystem.

Food chains show where energy is transferred and not who eats

who.

Example of a Food Chain

Food WebsA food web is a system of interconnected and interdependent food chains. It can also be defined as a network of food relationships through which nutrients and energy are passed from one living organism to another.
