Multiple Choice

What is the difference between a habitat and a niche in ecology?

• A habitat is a role in the community, while a niche is a specific area.

• A habitat is a specific area, while a niche is the role in the community.

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.

Multiple Choice
