Front

What is a consumer in ecological terms?

Back

A consumer is an organism that obtains energy by eating other organisms.

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

Back

Energy is lost to the environment at each level of the food pyramid, resulting in less mass being supported at each higher level.

Front

What type of symbiotic relationship is exemplified by hookworms feeding on their host's blood?

Back

The relationship is called parasitism, where one organism benefits at the expense of the other.

Front

What is the role of consumers in an ecosystem?

Back

Front

Explain the concept of energy transfer in a food chain.

Back

Energy transfer in a food chain occurs when one organism eats another, with energy being passed from the producer to the consumer, but with energy loss at each trophic level.

Front

What is the significance of decomposers in an ecosystem?

Back
