The trophic level of producers (photosynthetic organisms) has the most available energy in a biologic community. As a general (but not absolute) rule, every trophic level above this has 10% as much available energy as the level below it; primary consumers have 10% as much as producers, secondary consumers 1%, tertiary consumers .1%.
Only 10% of the energy will appear in the next tropic level.
What is the term for each step in the transfer of energy and matter within a biological community?
primary producer
Each tropic level is only able to use about 10% of the energy from its food. Because of this energy loss, there is usually not enough energy left to after a fourth tropic level to support anything higher.
Level A
the equator
The greeny pyramid is the best answer
In higher tropic levels, energy is lost because of the higher area of living. Metabolic activity is something else that plays a big part in the loss of energy at the tropic level.
The most energy is available at the producer level of the pyramid . As you move up the pyramid, each level has less energy available than the level below.
The base level or the lowest level uses sunlight. These are plants, trees, grasses and shrubs.
