Why do exotic species sometimes take over an ecosystem

Exotic species are those organisms which are not native to the specific area. When exotic species are introduced into a new ecosystem, the exotic species can grow at exponential rate because they often don't face the same factors that were inhibiting the growth in the original ecosystem. That’s why exotic species sometimes take over an ecosystem.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
