Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why are decomposers like bacteria and fungi crucial in ecosystems?
A
they parasitize large populations
B
they increase CO2 in the atmosphere
C
they return vital nutrients to the soil
D
they provide food for carnivores
Explanation: 

Detailed explanation-1: -Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.

Detailed explanation-2: -Decomposers like bacteria and fungi decompose dead plants and animals and recycle chemical nutrients like carbon and nitrogen back into the soil, air and water.

Detailed explanation-3: -Bacteria and fungi are called decomposers because bacteria and fungi break down the dead and decaying organic matter into simpler substances and provide the nutrients back to the soil. Advantages of decomposers to the environment:i They act as natural scavengers. ii They help in recycling of nutrients.

Detailed explanation-4: -The decomposers, certain soil bacteria and fungi, break down proteins in dead organisms and animal wastes, releasing ammonium ions which can be converted to other nitrogen compounds.

Detailed explanation-5: -Some fungi are decomposers which mean that they break down plant and animal debris, thus cycling nutrient and increasing their availability in the soil. They can also propel nitrogen fixation and phosphorus mobilization, two of the main nutrients required for plant development and productivity.
