Overlapping food chains with different pathways for the flow of food energy in an ecosystem.

Starts with radiant energy captured by producers(plants) through photosynthesis, and continues with energy flow from producers to consumers and finally to decomposers.

A system comparing all the biotic and abiotic factors in an area and all the interactions among them.

A diagram that show the trophic levels of organisms in a food web.

The position an organism occupies on the food web.

Organisms such as bacteria and fungi that break down the remains of dead plants and animals without the need for internal digestion.

A single, linear path showing the flow of energy from the sun to producer and through different levels of consumers.

Animals that eat secondary consumers.

Animals that eat other animals that eat plants.

An organism that gets their energy by feeding on producers in the food chain.

Animals that eat other animals.

Organisms that consume only plants.

An organism that must consume other organisms for nutrients.

Organisms that make complex, energy-containing biomolecules from simple inorganic molecules using energy captured from light or inorganic chemical compounds.

Energy Flow

Term	Definition
Food web	Overlapping food chains with different pathways for the flow of food energy in an ecosystem.
Grazing food web	Starts with radiant energy captured by producers(plants) through photosynthesis, and continues with energy flow from producers to consumers and finally to decomposers.
Ecosystem	A system comparing all the biotic and abiotic factors in an area and all the interactions among them.
Energy Pyramid	A diagram that show the trophic levels of organisms in a food web.
Trophic level	The position an organism occupies on the food web.
Decomposers	Organisms such as bacteria and fungi that break down the remains of dead plants and animals without the need for internal digestion.
Food chain	A single, linear path showing the flow of energy from the sun to producer and through different levels of consumers.
Tertiary consumers	Animals that eat secondary consumers.
Secondary consumers	Animals that eat other animals that eat plants.
Primary consumers	An organism that gets their energy by feeding on producers in the food chain.
Carnivores	Animals that eat other animals.
Herbivores	Organisms that consume only plants.
Consumers	An organism that must consume other organisms for nutrients.
Producers	Organisms that make complex, energy-containing biomolecules from simple inorganic molecules using energy captured from light or inorganic chemical compounds.
