Question

I will award a medal to any one who can help me answer these. thanks!

Why are populations that are more diverse usually more stable?

Assume two habitats have the same number of species. One habitat is predominantly one species with just a few of the other species. The other habitat had equal numbers of all the different species. Which will have the highest diversity index?

There are many human-caused losses of biodiversity, such as habitat destruction and introduction of invasive species. Are there any natural events that would alter the diversity index?

Answer 1

The one with equal numbers of all the different species. Because, when you have a lot more of many species you are at less of a risk for outside dangers; like invasive species.

Answer 2

what do you mean the one with equal numbers...?

Answer 3

you said that one was predominantly with one species, so the other one that has an equal number of many different species would have a higher diversity index.

Answer 4

wait which question are you answering...?

Answer 5

The second one, I was about to answer the others.

Answer 6

okay

Answer 7

As for the third one there are many different types of Natural events that can cause loss of biodiversity. Such as wildfires and flooding, is this what your looking for?

Answer 8

i believe so..... so what about the first question?

Answer 9

The first one is because when you have a more diverse ecosystem you are less likely to have a keystone species die out. Like if a jaguar for example were to run out of one of its main source of food, then it would die out. But when you have many other animals that it can use for prey it is less likely to kill off keystone species.

Answer 10
