Why are non-native species dangerous to ecosystems?

Answer & explanation:

Non-native species may be animals, plants or microorganisms introduced into an ecosystem of which they are not originally part, but where they adapt and come to dominate, harming natural processes and native organisms.

When a new species is introduced into an environment other than its own, it may compete with others, prey heavily on some species, over-breed and even cause disease.

Therefore, it can be concluded that this action may cause the destruction of some species, directly affecting the balance of that ecosystem.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
