Multiple Choice

What sentence best describes how energy flows through this pyramid?

• Energy is transferred down each level of the energy pyramid.

• The energy lost at each level is consumed by organisms in the top level.

• Energy is transferred from organisms in one level to those in the level above.

• The organisms at the bottom level provide energy directly to organisms in all the other levels.

Multiple Choice

What do the arrows in the food chain indicate about the flow of energy in an ecosystem?

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

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

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

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