In the food chain, what do the arrows indicate about the flow of energy in an ecosystem?

• Energy is continuously recycled by the organisms in an ecosystem.

• Organisms at the end of the food chain receive more energy than those at the beginning

• More of the available energy in an ecosystem is given to large animals than to small animals.

• Energy flows in one direction in an ecosystem from producers to consumers.

Organisms at the beginning of the food chain receive more matter than those at the end.

• Matter is continuously recycled by the organisms in an ecosystem, but the amount of matter in an ecosystem stays the same.

• Matter in an ecosystem flows in one direction and is eventually lost.

• There is more matter available to the top-level consumers in an ecosystem.

• Matter in an ecosystem flows in one direction. The matter starts with the consumers and is transferred to the producers.
