Expert Solution

Step 1

The ecosystem is made up of a biological community that exists in a region along with physical and chemical factors that constitute its abiotic or non living components. The ecosystem constitutes both biotic and abiotic factors.

The biotic factors of an ecosystem include producers (autotrophs), consumers (heterotrophs) and decomposers (fungi and some bacteria).

The abiotic factors of an ecosystem include sunlight, air, water, minerals, temperature, turbidity, wind , altitude.

The biotic and abiotic components of an ecosystem are linked through cycling of nutrients and flow of energy
