Yes. If animal in captivity stop breeding then the species would decrease.
The loss of habitats has resulted in a clear decrease in diatom species
No, because water have actually more pressure than any human beings or other animals species. Water pressure could increase and decrease.
Some animals can handle captivity fairly well. Other species such as the dolphin or killer whale don't handle captivity well: Teeth break from chomping on steel bars (lack of stimulation), premature deaths, they get stressed (separated from pods) etc.
The diet and lack of animals that could cause harm to the wolf enable it to live longer in captivity.
No, because water have actually more pressure than any human beings or other animals species. Water pressure could increase and decrease.
There could be many reasons why. Their predators could have decreased, or the food that they have increases.
There is a great list of things we could do. We could: (1) make laws protecting the puma species, (2) capture and raise alot in captivity (3) make a reserve (not in captivity) for them to roam, etc.
because different species could mate and make new species which could cause diseases and disabilities in new species.
For once, it would be a good thing to see a species decline a bit. The adaptable coyote is found now in great numbers where it is not native, and has become a threat to native species and livestock, even children.
The effects of living in a zoo an animal experiences depends on the type of animal and whether or not the animal was born in captivity. Many animals are clearly stressed by being held in captivity and show signs of depression and mental illness.
Animals get endangered from hunting because there could be the possibility of overhunting, which will reduce the population drastically from a species. Humans could also set traps that animals can step in. All in all, hunting could be a possibility of extinction of a species.
It could impact the ecosystem immensely. It would decrease the number of animals that feed off the producers, and then decrease the number of animals that feed off those animals etc. Its a massive chain, as soon as you change one little thing everything else changes
