Food Chain
Energy Pyramid
Food chains show a flow of ________ from the organism that is eaten to the organism that is eating it.
A possible start to the food chain and are in the first trophic level of an energy pyramid
Eats producers to get energy and is in the second trophic level of the energy pyramid.
Energy is lost due to unusable heat and waste
Type of energy lost to the environment in a food chain
The variable that is measured in an experiment. The effect in an experiment. We can have only one of these in an experiment
The variable that is kept the same in an experiment so that the results are not thrown off. We need as many as possible of these
A group of overlapping food chains connected together in an ecosystem (complex).
Eats other carnivores to get energy and is in the fourth energy level of the trophic level.
Different feeding positions in a food chain or web.
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.
The variable that is changed in an experiment. The cause. We can have only one of these in each experiment
Original source of energy for a food chain
Eats herbivores to get energy and is in the third trophic level of the energy pyramid.
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
Amount of energy lost to the environment as heat OR used by the organism to stay alive
