Why only 10% of energy is transferred to the next trophic level
Tertiary Consumer
A group of overlapping food chains connected together in an ecosystem (complex). Energy flows 1 way. Matter is recycled.
Amount of energy lost to the environment as heat OR used by the organism to stay alive
This recycles over-and-over between organisms in a food web/ecosystem as one organism eats another. It never leaves the ecosystem. It gets re-used.
Type/form of energy each organism in a food chain is AND the form of energy passes along from one organism to another.
When energy moves from one organism (object) to another organism (object).
When energy changes from one type of energy to another (different) type of energy
Type of energy lost to the environment in a food chain
A possible start to the food chain and are in the first trophic level of an energy pyramid
Original source of energy for a food chain
A good way to show how energy moves from one feeding level to another in a food chain.
The amount of energy passed when one organism eats another in the next trophic level.
This moves in a one-way direction into an ecosystem from the sun. Then through an ecosystem as one organism eats another. Then, out of the ecosystem through heat and organisms using the energy.
series of steps in an ecosystem in which organisms transfer energy AND transfer matter by eating and being eaten. Energy flows 1 way. Matter is recycled.
Eats producers to get energy and is in the 2nd trophic level of the energy pyramid.
Different feeding positions in a food chain or web.
Eats herbivores to get energy and is in the 3rd trophic level of the energy pyramid.
Energy is lost due to the organism using energy for living, unusable heat loss, and waste
Eats other carnivores or omnivores to get energy and is in the 4th energy level of the trophic level.
