Bears have very little predators besides humans and the occassional pack of wolves that stumble upon an ill or dying bear. This means that the only groups affected are their prey and other predators of their prey. This may cause a slight disturbance in the food web however, this difference will decrease as time goes by. The fact that there will be more of the bears' prey around and the fact that there will be more food for other predators of their prey will even things out over time.
If they went extinct the whole food chain would be out of balance.
It would effect the food chain and other marine life would become extinct
polar bears are a huge part of the food chain in arctic regions and there would be an overpopulation of many animals.
It's never good to remove an apex predator from an environment. Bears have their place, like removing the sick and weak animals from the population, so they won't breed and maybe pass on the sickly genes to their offspring.
tigers and leopards eat orangutans
We would miss them so much
the whole food chain would be effed up and we would cease to exist o_O
Kelp is intertwined in multiple food chains. If sea urchins go extinct, the other organism will feel in the gaps.
They won't and it would not affect our food chain. It would be a terrible loss to the planet though. Fortunately, they are not endangered and their numbers are still growing. They now number well over 20,000.
every onr in the food chain will die lol i direction rock
If the deer became extinct then ,all the greenery would overgrow , and all the animals that eat the deer would die as well because the deer was there main food source.
The animal population would tend to go "extinct" -Dr. Bosch
