• Organism that consumes other organisms for energy.

• Organism that decomposes organic material.

• Organism that relies on sunlight for energy.

What happens to energy as it moves up the food chain?

• Energy increases as it moves from producers to primary consumers to higher trophic levels.

• Energy remains constant as it moves through the food chain.

• Energy decreases as it moves from producers to primary consumers to higher trophic levels.

• Energy is lost only at the highest trophic levels.

What is a food web?

• A simple linear sequence of organisms that eat one another.

• A complex network of interconnected food chains in an ecosystem.

• A type of food chain that only includes plants.
