Question

question 19 points 3 why may the impact of introducing an organism into an ecosystem be very harsh to the native organisms? new organisms may not have natural predators. natural predators are very numerous. introducing new organisms enhances the size of the population in the ecosystem introducing new organism leads to the development of biodiversity

Explanation:

When a new organism is introduced, if it has no natural predators in the new ecosystem, it can reproduce unchecked and out - compete native organisms for resources, harming them. Other options either do not explain harm to native organisms (enhancing population size or biodiversity development) or are counter - intuitive (numerous natural predators would likely limit rather than harm native organisms).

Answer:

New organisms may not have natural predators.
