The correct options are as follows:
2. THE VEGETATION IT EATS INCREASES AND THEN DECREASES REPEATEDLY WITH CHANGING SEASONS.
Some population of living organism usually undergo cyclic population changes in size. Cyclic oscillation results in repeated rise and fall in the population size of the concerned living organism over time. cyclic population changes are often brought about by interactions between populations of different species. For example, fluctuations in food availability can bring about cyclic population changes.
3. THE DEER POPULATION WILL INCREASE AND STRIP THE REGION OF VEGETATION.
The pumas and the panthers are the predators that feed on the deer. If these predators are eliminated, the number of deer in the region will increase drastically and this will be very detrimental to the health of the vegetation in the region. This is because, the deer, in their large number will feed unrestrainly on the vegetation until there is nothing left and this will affect the concerned ecosystem negatively.
4. THE ECOSYSTEM COLLAPSES.
A keystone specie refers to a specie of organism, which has a disproportionately large effects on its environment compare to its abundance or population. Such specie play crucial roles in the maintenance of the structure of the ecological community, that is, they largely determine the type and number of other specie in the community. Elimination of keystone species will leads to the collapse of the concerned ecosystem.
