Question

what part of the food chain do primary consumers occupy

Answer 1

Primary consumers occupy the second trophic level of a food chain. They are organisms (typically herbivores or plant-eating omnivores) that feed on primary producers (plants, algae, phytoplankton) and pass that energy on to secondary consumers (carnivores and omnivores).

Examples: rabbits, deer, caterpillars, zooplankton, and many grazing insects.
