What would happen if fish went extinct how would it affect the animals who feed on them?

If all fish species went extinct, all of the animals that eat fish would be forced to find a new prey. Another consequence would be that the environment in which they live would start deteriorating because there would be nothing to keep watch over the environment.

Explanation:

Take coral reefs for example. Of the numerous roles performed by reef fishes, nearly 40 percent are performed by a single species. If these specialists disappear, there’s no one waiting in the wings to step in and do their job. High biodiversity clearly does not necessarily ensure high resilience or robustness.

Hope This Helps!!

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
