Question:- Fiddler crabs and soldier crabs are both examples of consumers because they eat the algae and bacteria off of particles of sand and mud.

A) Primary (herbivores)

B) Secondary

C) Tertiary

D) Decomposer

Answer:- The correct answer of B.Secondary

Explanation:

Fiddler crabs and soldier crabs are secondary consumers since they feed on primary ones. Primary consumers are organisms that eat producers making their own food through photosynthesis or chemosynthesis. The producers are plants, algae and some bacteria. Fiddler crabs and soldier crabs are consumers that feed as primary on the algae and bacteria in sand, mud. Fiddler crabs and soldier crabs are secondary consumers in the food chain as they eat these primary ones.

Secondary consumers like fiddler crabs and soldier crabs get their energy by feeding on other organisms instead of producing food themselves, a characteristic that they share with primary producers. They mainly feed on primary consumers and are located at the second trophic level in their ecosystems. As secondary consumers, they are very effective energy conduits that relay the transfer of power from primary producers and consumers to higher levels of consumption. For the efficient flow of energy in an ecosystem, secondary consumers such as fiddler crabs and soldier crabs must consume primary consumers. They help in consuming algae, bacteria and other primary consumers hence supporting the larger food web.
