(d) Mice and Rabbit

Primary consumers are herbivores (second trophic level) that eat producers directly. In this food web, Mice eat Seeds/Plants and Rabbit eats Plants/Grass — both feed on producers.

• Primary consumers = organisms that eat producers (plants/seeds) directly = second trophic level.
• Mice (Seeds→Mice, Plants→Mice) and Rabbit (Plants→Rabbit, Grass→Rabbit) both feed on producers, making them primary consumers.
• Cat, Fox, and Bear eat Mice/Rabbit, so they are secondary/tertiary consumers.
• Examiner expects you to identify the trophic level from arrow direction in the food web.
