nasty-shy [4]

Answer:

coatis would increase

sloths would increase

fruit bats would increase

Explanation:

The boa constrictor in this food chain is the top predator, thus it is on the top of the food chain. It preys on several of the animals on this list, such as the coati, sloth, and fruit bats, so it is regulating their numbers. If the boa constrictor is removed from the ecosystem, the ecosystem will lose its predator, so the animals on which the boa constrictor preyed upon will have no threat, thus will experience rapid increase in their numbers. The coatis, sloths, and fruit bats, all will be predator free in this scenario, so they will all experience increase in their population, which in turn will have big effect on all other species in the ecosystem.

Thomas Malthus predicted that the human population is reproducing faster than its death race and will lead to growing faster than space and food supplies needed to sustain it. Darwin concluded further that If all offspring of almost any species survived for several generations, they would overrun the world and therefore a healthy and meaningful competition is present and to overcome this natural selection takes place as the individual adapt will ultimately survive.

In the beginning all the contents were grouped together as one giant landmass. What role did separation of them play in evolutio
Lena [83]
When the continents separated, organisms were forced to be placed in different locations with different environmental conditions. In order to survive in their new environment, over time, various flora and fauna developed various body mechanisms to cope up. This brought up the speciation of flora and fauna.
