What are the three trophic levels? Give an example of each.

Each level of consumption in a food chain is called a trophic level.

First trophic level is autotrophs (producers). Example: Green plants. they prepare their own food.

Second trophic level: Herbivores (primary consumers). example: rabbit. they depend on autotrophs for their food energy.

Third trophic level: Carnivores (secondary consumers). Example: lion. They depend on primary consumers for food energy.

Solution Summary

Biodiversity is the variation of taxonomic life forms within a given ecosystem or a biome. It is the measure of health of the biological system to indicate the degree to which the species are diverse and the count of viable versus extinct species. Each level of consumption in a food chain is called a trophic level.
