An Energy Pyramid in the Tundra Biome
The tundra is a challenging environment, and the short growing season limits plant growth. The tundra produces only 600 Kilocalories per square meter per year for the herbivores to eat. Here is a diagram of the energy available at teach trophic level.
The food chain here supports only three trophic levels because carnivores have to cover a lot of ground to find enough to eat.
