Question

Which of the following does not contribute directly to the recycling pathways of trophics?

• A. Bacteria and fungi feeders
• B. Plants
• C. Carnivores
• D. Herbivores

Answer 1

The correct option is A Bacteria and fungi feeders

The nutrient cycle or recycling pathway is the movement and exchange of organic and inorganic matter back into the production of living matter. Bacteria and fungi are considered as primary detritus feeders. They are involved in the decomposition of the dead matter. These dead organisms are then converted to other forms which are then acted upon by the secondary consumers of the detritus food chain. The contribution by bacteria and fungi is considered negligible because they are the primary feeders and are not directly involved in the nutrient cycle. However, plants, herbivores, and carnivores form the main units of the grazing food chain.

So, the correct answer is option A.
