B. have more offspring
C. make better predators
D. have no competitors
Answers
Answer:
Introduced species often take over an ecosystem because they usually because………
Explanation:
First getting familiar with introduced species, these are generally termed as species that might have been raised up in captivity. Now since these species are raised in captivity, so it is obvious that they are much different as compared to ones that are raised in natural environment.
Now looking at the options that you have provided here….
(A) need fewer resources
This certainly cannot be the right answer as species that are raised in captivity certainly are not deprived of any resources that they need for their survival.
(B) Have more offspring
Well even if raised in captivity still it is obvious that they are able to reproduce normally. In case of mating it is certain that they will have same number of offspring as others of the same kind.
(C) Make better predators
I don’t think that just because a species have been raised in captivity and reintroduced in a new place, so they may be considered as better or superior predator.
(D) Have no competitors
This certainly can be one of the possible answers. It is obvious that species that are on the edge of extinction are also the one that are being raised in captivity and then later on reintroduced back into the natural habitat so they can multiply their numbers.
So the correct answer is D.
Answer:
he newly introduced species are able to survive because they don’t have a fear of predators and they have more offsprings.
Explanation:
When species are introduced into the new environment, some of them are not able t survive while others are able to thrive. The reason for this is that they find optimal conditions for growth, reproduction and adapt to the new environment, thus they are able to survive
