Answer 2

Bacteria in soil feed on Organic matter.

Option A

EXPLANATION:

• The bacteria on soil feed on organic matter present in soil. Bacteria belong to a group of animals in ecosystems, and they are called as Decomposers.
• This group of animals contains various organisms like bacteria, fungi, protozoa, nematodes, etc.
• Their primary function is to breakdown the complex organic matter into simpler compound and they release it back to environment to be used again.
• For example, the starch present in leaves is broken down into simpler water and other molecules like oxygen or carbon dioxide.
• In this way, they play significant role in maintaining biogeochemical cycles and other nutrient cycles of ecosystems and are crucial for proper functioning of our ecosystems.
