Question

1. define trophic levels (1pt). 14. go back to the diagram above and label the producer, primary consumer, secondary consumer, and tertiary consumer. (1pt)

Explanation:

Trophic levels are hierarchical levels in an ecosystem, each representing a different position in the food - chain. Producers are organisms that produce their own food through photosynthesis, like plants. Primary consumers eat producers (herbivores). Secondary consumers eat primary consumers (carnivores or omnivores). Tertiary consumers eat secondary consumers.

Answer:

1. Trophic levels are the hierarchical levels in an ecosystem based on the organism's position in the food - chain. Producers are at the base, followed by primary consumers (herbivores), then secondary consumers (carnivores or omnivores that eat herbivores), and finally tertiary consumers (carnivores that eat other carnivores).
2. Without seeing the specific diagram, in general, plants or other autotrophs are labeled as producers, herbivores as primary consumers, small carnivores or omnivores that eat herbivores as secondary consumers, and large carnivores that eat other carnivores as tertiary consumers.
