What role do primary consumers play in an ecosystem?

Primary consumers play a vital role in an ecosystem by consuming primary producers, which are typically plants and other photosynthetic organisms. This interaction is essential for energy transfer within the food web. By feeding on primary producers, primary consumers obtain the energy stored in the plant tissues, which is converted from sunlight through photosynthesis.

This process not only supports the primary consumers but also indirectly benefits higher trophic levels, such as secondary consumers, who rely on them for energy. Thus, primary consumers serve as a critical link in the ecosystem, supporting biodiversity and maintaining the balance of energy flow.
