How can pollution can affect food chains?

Answer 1

Pollution affects many smaller organisms.

For example, if an ocean was polluted this may harm the fish living in it. It would not directly affect the bear living on shore. However, if the fish died from the pollutants in the water, the bear would have no fish to eat and would die. Then, the birds that the bears used to hunt would grow in population because the bears that used to hunt them would be dead. Because there were so many birds, they would need more worms and would eventually starve when they ate all the worms. The pollution of the water just led to four species extinction. Just think about how without these species other animals would grow or shrink in population.

Food chains are needed to keep all organisms in balance. If one species grows in population they affect the whole food chain. Also, if they decrease they effect the food chain too. Pollution harms many animals and disrupts their food patterns and therefore off sets the whole food chain.

sorry this is long! !! :)

Answer 2

Pollution can harm food chains by contaminating the air, water, and soil which can be absorbed by plants and animals. This can lead to bioaccumulation of toxins in organisms at higher trophic levels, causing harm to predators and potentially disrupting the balance of ecosystems. Additionally, pollution can reduce the availability of food sources by destroying habitats or altering the populations of key species in the food chain.

Answer 3

They all die because the food chain is changed.

Have a good day!! : )
