Answer:
When many different species live in an environment, the environment has high<em> biodiversity</em>. If the number of predators increase in an area, the immediate effect will be a<em> unstable ecosystem (</em><em>decrease in the population of prey</em>.)
Explanation:
In ecology, biodiversity can be described as the different plants and animals which live in a habitat. If a habitat has many kind of different species, then the habitat or ecosystem will have a wide biodiversity. The wider the biodiversity, the more stable an ecosystem will be.
If the number of predators will increase then the ecosystem will become unstable. There will be more competition for resources.
