Question

Which part of a food chain is affected by one animal becoming extinct?

• A. The whole food chain is affected.
• B. Only animals at the top of the food chain are affected.
• C. Only plants and animals at the bottom of the food chain are affected.
• D. Producers and decomposers are affected.

Answer 1

The correct option is B

Only animals at the top of the food chain are affected.

Only animals at the top of the food chain are affected.

All living organisms hold a place in the food chain. For example, plants produce energy from sunlight and provide nutrients for animals, such as rabbits, which are consumed by meat-eating predators, such as mountain lions. Members of the food chain interact with one another and with their environment as part of a complex, interlocking ecological system. Extinction of one species can have a cascading effect on others.
