DENDROLOGY

Detailed explanation-1: -Some introduced species may become invasive when they possess a built-in competitive advantage over indigenous species in invaded areas. Under these circumstances, new arrivals can establish breeding populations and thrive, especially if the ecosystem lacks natural predators capable of keeping them in check.

Detailed explanation-2: -Invasive alien species are animals, plants, fungi and microorganisms entered and established in the environment from outside of their natural habitat. They reproduce rapidly, out-compete native species for food, water and space, and are one of the main causes of global biodiversity loss.

Detailed explanation-3: -Introduced species often change the ecological balance, or the condition of equilibrium among the different species in an ecosystem; and one way that the ecological balance is often changed is through local extinction, which is when a species ceases to exist in a local area.
