Question

In a grazing food chain.

• A. Primary consumers eat detritus.
• B. Primary consumers eat photosynthetic organisms.
• C. Secondary consumers eat detritus.
• D. Secondary consumers eat photosynthetic organisms.

Answer 1

The correct option is B

Primary consumers eat photosynthetic organisms.

The correct option is B.

Explanation for the correct option:

1. Photosynthesis provides energy to the lowest trophic level of a grazing food chain.
2. The grazing food chain begins with producers such as green plants and progresses to herbivores and predators.
3. This form of the food chain is completely reliant on sunlight for photosynthesis.
4. The grazing food chain is constantly a source of energy for the ecosystem.
5. This food chain contributes to the fixation of inorganic nutrients.
6. Primary consumers are creatures that devour the primary producers.
7. Plant-eaters, commonly known as herbivores, are the primary consumers. For example, goats and deer.

Explanation for the incorrect options:

Option A:

Detritivores are the primary consumers in a detritus food chain.

Option C:

Predators consume the detrivores. in the food cycle of detritus.

Option D:

1. Secondary consumers are creatures that feed on main consumers.
2. Secondary consumers are often meat-eaters, sometimes known as carnivores. For instance, Fox.

Final answer: In a grazing food chain primary consumers eat photosynthetic organisms.
