Detailed explanation-1: -Native: a species that originated and developed in its surrounding habitat and has adapted to living in that particular environment. (It can become aggressive, similar to an invasive species.) Invasive: a species of plant or animal that outcompetes other species, causing damage to an ecosystem.
Detailed explanation-2: -An invasive species is an organism that is not indigenous, or native, to a particular area. Invasive species can cause great economic and environmental harm to the new area.
Detailed explanation-3: -An invasive species can be any kind of living organism-an amphibian (like the cane toad), plant, insect, fish, fungus, bacteria, or even an organism’s seeds or eggs-that is not native to an ecosystem and causes harm. They can harm the environment, the economy, or even human health.
Detailed explanation-4: -A native species is found in a certain ecosystem due to natural processes such as natural distribution. The koala, for example, is native to Australia. No human intervention brought a native species to the area or influenced its spread to that area. Native species are also sometimes called indigenous species.
