Detailed explanation-1: -If wolves prey on deer for food, what will most likely happen to the deer population if wolves are removed from an area where deer live? The population of deer will increase.

Detailed explanation-2: -Population Explosions The most obvious result of the removal of the top predators in an ecosystem is a population explosion in the prey species. Predators keep herbivore populations in check. The reverse is also true, of course–predator populations are limited by the availability of prey.

Detailed explanation-3: -If decomposers were removed from a food chain, there would be a break down in the flow of matter and energy. Waste and dead organisms would pile up. Producers would not have enough nutrients because, within the waste and dead organisms, nutrients would not be released back into the ecosystem.

Detailed explanation-4: -What happens to a population and to competition when there is a reduction of living space? The population expands and competition intensifies.

Detailed explanation-5: -Symbiosis is a term describing any relationship or interaction between two dissimilar organisms. The specific kind of symbiosis depends on whether either or both organisms benefit from the relationship.
