Detailed Solution

The ecosystem is at homeostasis when all of the populations are in harmony.

In an ecosystem, as species go extinct, they are taken out of the food chain. Animals that were dependent on the newly extinct species have to find new food sources or starve. This can negatively affect the populations of other plants or animals.

Furthermore, if a predator goes extinct, its prey population can proliferate, affecting the local ecosystem. Therefore, the whole food chain is affected if one animal goes extinct.
