The rate at which organic material is produced by photosynthetic organisms in an ecosystem. It determines the amount of energy available in an ecosystem.

Organisms that first capture energy from the sun, such as plants, some kinds of bacteria, and algae.

Those organisms that eat (consume) plants or other organisms to get energy.

All organisms are assigned to a specific level to show how energy moves through an ecosystem.

The path of energy through the trophic levels of an ecosystem.

Found on the second trophic level, these organisms eat only plants.

Found on the third trophic level, these organisms eat herbivores and are classified as secondary consumers.

Organisms that eat both plants and animals. They are both herbivores and carnivores.

A complicated, interconnected group of food chains.

A diagram in which each trophic level is represented by a block and the blocks are stacked on top of one another with the lowest trophic level on the bottom.

The dry weight of tissue and other organic matter found in a specific ecosystem.

Question	Answer
Primary Productivity	The rate at which organic material is produced by photosynthetic organisms in an ecosystem. It determines the amount of energy available in an ecosystem.
Producer	Organisms that first capture energy from the sun, such as plants, some kinds of bacteria, and algae.
Consumer	Those organisms that eat (consume) plants or other organisms to get energy.
Trophic Level	All organisms are assigned to a specific level to show how energy moves through an ecosystem.
Food Chain	The path of energy through the trophic levels of an ecosystem.
Herbivore	Found on the second trophic level, these organisms eat only plants.
Carnivore	Found on the third trophic level, these organisms eat herbivores and are classified as secondary consumers.
Omnivore	Organisms that eat both plants and animals. They are both herbivores and carnivores.
Food Web	A complicated, interconnected group of food chains.
Energy Pyramid	A diagram in which each trophic level is represented by a block and the blocks are stacked on top of one another with the lowest trophic level on the bottom.
