Increase at first. However, once their population gets too large then their food sources will become scarce and disease is likely to spread quickly. Their numbers may drop again due to starvation and sickness.
If herbivores were removed from the planet, the food chain wouldn't have a bottom. Some carnivores eat smaller carnivores, but the lowest carnivore on the food chain would die if herbivores would be removed, causing a chain reaction and, well, the carnivores that eat that carnivore would die, and the carnivores that eat THAT carnivore will die... etc. The world would be a total mess.
There would initially be an enormous population explosion until they exceeded the available resources, then the population would suddenly crash.
The population has not reached carrying compacity is correct on apex
Vestigial structures do not harm the organism. Nature selects against only harmful traits.
The population of their prey would grow dramatically, resulting in mass extinction due to lack of food, proliferation of disease, and competition, if the predators were permanently removed and no others were introduced.
When a living thing is removed from a food web the population of it's predators will decrease and the population of its prey will increase, disrupting the ecosystem of the living thing.

If the secondary consumers are removed then the apex predators will die with no prey to prey on.
If mountain lions are removed from a natural park type of setting, and we are assuming that the lions are the sole predator of the deer in the area, then what you would see is an increase in the deer population. As long as there are enough resources in the park setting (food, water, space, mates, etc.,) then the population will continue to rise until they begin to run out of resources. The deer will probably rather quickly overpopulate the area, and will strip the park of the resources that they need to survive, so the population will crash. Most likely the park service that manages the area will allow some hunting of the deer in order to control the population. This is actually a very common practice since the natural predators of deer are not too common in most parts of the US at least, and so hunting of the deer is allowed to keep them from overpopulating and starving to death.
If an animal were to be removed from a food chain, the entire ecosystem could easily fall apart or futhermore be destroyed. Say that a herbivore such as a mouse that feeds on grass was too be removed. And that the mouse would be eaten by a snake..the snake population would decrease from starvation and the grass would increase.
The frog population will be decreased or vanished
since the grass is the crickets food the population of crickets would decrease if all the grass was removed
The natural resources in the arctic are not being removed very quickly because of the permafrost. The permafrost is hard to dig up, pretty much too hard. Because of that, the natural recourses resources are not being removed very quickly!

Yes its a natural system to removed bodily waste
replace the natural lens that is removed during cataract surgery
If a herbivore is removed from the food chain ,the level one carnivores which would otherwise eat the herbivore,would starve to death,as they can not eat producers nor can they eat level 2 or level 3 carnivores. ex. in a foodchain of grass-grasshopper-frog-snake ,if we remove grasshopper(herbivore),frog the level 1 carnivore,would die of starvation as it can not eat grass,nor can it eat snake.It will get in to other foodchains for survival and will disturb the regular echosystem.
