Question

Without the ..... in a food web many chemicals would not be recycled.

Answer 1

Sun is an endless source of energy, but the chemical materials of the environment are not inexhaustible. The producers utilize inorganic substances and fix solar energy into the chemical energy of organic compounds. This stored energy is then passed to consumers by repeated eating and being eaten. Decomposes act on dead animals and plants and return the chemical nutrients to the environment. They also make space available for new producers. Without this, all life will ultimately cease to exist. Thus, the decomposers have a crucial role in the ecosystem.

So, the correct answer is 'Decomposers'.
