Primary Consumer
Energy Transfer
A group of overlapping food chains connected together in an ecosystem (complex). Energy flows 1 way. Matter is recycled.
A good way to show how energy moves from one feeding level to another in a food chain.
Eats other carnivores or omnivores to get energy and is in the 4th energy level of the trophic level.
Original source of energy for a food chain
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.
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
Different feeding positions in a food chain or web.
Type/form of energy each organism in a food chain is AND the form of energy passes along from one organism to another.
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.
Energy is lost due to the organism using energy for living, unusable heat loss, and waste
Eats herbivores to get energy and is in the 3rd trophic level of the energy pyramid.
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.
Eats producers to get energy and is in the 2nd trophic level of the energy pyramid.
Type of energy lost to the environment in a food chain
Amount of energy lost to the environment as heat OR used by the organism to stay alive
The amount of energy passed when one organism eats another in the next trophic level.
A possible start to the food chain and are in the first trophic level of an energy pyramid
