How can we measure the health of an ecosystem? And write it like a 7 grader

Answer 1

One way we can measure the health of an ecosystem is by looking at the number and variety of different species living there. If there are a lot of different plants and animals in an ecosystem, that usually means it is healthy. Another way to measure ecosystem health is by looking at the amount of pollution in the air, water, and soil. If there is a lot of pollution, it can harm the plants and animals that live there. We can also look at how well the ecosystem is able to provide food, water, and shelter for the creatures that live there. By looking at all of these factors, scientists can get a good idea of how healthy an ecosystem is and if it needs any help to get better.
