Invasive species" is defined as aspecies that is: 1) non-native (or alien) to the ecosystem under consideration and. 2) whose introduction causes or is likely to cause economic or environmental harm or harm to human health.
Invasive species in my words, ( i learned this recently) are the animals or insects that grow quickly in population. like in florida, the python is a big one because it invades the everglades and could take over some animals by eating them. (Or ducks, fish etc)
