Describe how a human action such as removing a top predator, or adding a species, can have an impact on many species in an ecosystem
What will be an ideal response?
Removing a top predator (which can typically be a keystone species) can have a major impact on an ecosystem. Removing such a predator would reduce environmental resistance on their prey, which would in turn lead to potential J-curve growth of the prey. This has a trickledown effect on many organisms in the ecosystem. On the other hand, if humans add species to an ecosystem we run the risk of the non-native species becoming invasive and competing with or destroying native species in the ecosystem. This could also have a trickledown effect on many organisms in the ecosystem.
