How Changing Abiotic and Biotic Factors Changes the Ecosystem

Changing the abiotic and biotic factors can have dramatic consequences for an ecosystem. For example, warmer temperature means that polar bears have a harder time finding food. Pollution and toxic chemicals can change the pH level within soil or water, harming plants and fish.

Imbalances in the number of predators and prey can harm an ecosystem. As an example, if the number of deer within a forest is reduced, plants may grow unchecked.
