Question

In an ecosystem, bacteria are considered as

• A. Microconsumers
• B. Macroconsumers
• C. Primary consumers
• D. Secondary consumers

Answer 1

The correct option is A Microconsumers

In an ecosystem, bacteria play an important role. Irrespective of the ecosystem being aquatic or terrestrial, the cycling of carbon, nitrogen and sulphur is completed due to the work done by the bacteria. The bacteria which are microscopic, help in decomposing or breaking down the dead organisms in the ecosystem and thereby releasing the nutrients back into the environment. These are, therefore, the microconsumers.
