Answer:
To make energy available for transfer to higher trophic levels.
Explanation:
- <em>Primary consumers </em>are the organisms that feed directly on the autotrophs to obtain energy.
- These consumers thus help to transfer energy to higher trophic levels that are <em>secondary consumers.</em>
- An example is the goat feeding on a plant is a primary consumer that directly obtains its energy from the plant. However, by feeding on the plant, it makes energy available for the secondary consumer, which in this case would be a lion.
