Interaction with Ecosystems __#7 The Energy Pyramid __

Every time a consumer eats, they take in only 10% of the sun’s energy from that plant or animal. The unit of measure for the energy pyramid is Kilo Calorie (Kcal) / square metre / year.

For example, in the tundra, the producers take in 600 Kcal/m 2 /year of the sun's energy. If a herbivore eats a plant they woud receive 60 Kcal/m 2 /year of energy. If a carnivore eats a herbivore, they would only receive 6 Kcal/m 2 /year.

Below is a picture of a Grassland Energy Pyramid. The grassland pyramid receives 1200 Kcal/m 2 /year.

Below is a graph of Energy Pyramids from the different Biomes we have been studying.



What is a Biome? It is an large area of the earth that supports specific plant and animal life. These plants and animals are detemined by the climate of the biome. For example: Tundra has a low temperature and very little precipitation. That means no trees and permafrost. Only certain types of animals can live in this environment. Polar bears are one type of animal.
