Presentation transcript:

Energy Pyramid

Pyramid of Energy -Pyramid shows amount of energy in each trophic level - Only 10% of energy from a trophic level is passed on to the next level - the missing 90% is released as heat of metabolism

Energy pyramid

*Only 10% of energy gets passed to the next trophic level

Biomass: Biomass needs energy the total weight of living things at a trophic level Biomass needs energy

Biomass Pyramid Lower trophic levels have more biomass

Biomass Pyramid

Pyramid of Numbers population size usually decreases at each trophic level

there are exceptions to the pyramid of numbers *there are exceptions to the pyramid of numbers* example: 1 tree is food for thousands of insects
