Question

Which trophic level ingests the most biomass in order to receive the energy they need?
A. producers
B. primary consumers
C. tertiary consumers
D. secondary consumers

Answer 1

A. producers

Producers, or autotrophs, are at the first trophic level and convert solar energy into biomass through photosynthesis. They have the most biomass because they form the foundation of the food chain and are consumed by primary consumers, secondary consumers, and tertiary consumers. Ultimately, primary consumers (herbivores) also ingest a significant amount of biomass from producers, but producers themselves represent the most biomass overall in an ecosystem.
