Why do foreign plant and animal species only become invasive in their new habitats?
In: Biology
Each habitat (ecosystem) is balanced by default; from plants to animals, the system has found a way to sustain all it’s population.
When a sudden change occurs, such as introducing a foreign species, a new members needs to be placed in the balance. Simplifying, it’ll need something to eat and something that eats it to become part of the ecosystem.
Species become invasive when they find a way to feed in the new system but have no other beings feeding from them.
