Question

Most food chains contain bacteria because bacteria act as:

• A. Primary consumers
• B. Secondary consumers
• C. Scavengers
• D. Decomposers
• E. Producers

Answer 1

Answer: (D)

Decomposers

Decomposers recycle the nutrients in an ecosystem. Bacteria and fungi act as major decomposers feed on organic matter present in the dead bodies of animals and plants. Decomposers in turn break down the organic matter present in the dead animals to simple nutrients in the soil. This organic matter is used by plants to grow.

Thus, the correct answer is option D.
