Why might organisms emigrate from an area?

Answer 1

they dont want to upset the owner and want you to remember them happy and not about to die I doubt the pet is thinking such grand thoughts. My third cat in a row, who was very ill, just disappeared as the previous two did. I think it must be instinctual (our second cat was a rescue who was sick with cancer and not attached to us). I think that, especially in the wild, if a animal died in its lair, the smell of the decomposing body would bring predators/scavengers which could threaten the rest of that family. It must be innate in animals (carried over to domesticated pets like cats) to drag themselves away from their home if they know they are dying as a last brave effort to save their family. I don't know this for fact but it makes the most sense to me.

Answer 2

Because people or natural disasters make the habitat unsuitable for the animal to live in. This happens when lumberjacks come, hurricanes devastate, or when a new animal species is introduced to the environment and "Out—Completes" the other animals for food, water, or homes.

Answer 3

Animals can often face problems in their new habitats because they adapt to the habitat the lived in before. Animals like the polar bear, adapt to the environment that they live in, allowing their white coat to camoflauge them against hunters etc, and their thick oily fur to keep them feeling warm and water-resistant. The polar bear would be less well adapted if he moved to a different environment as he is only adapted to his own habitat.

Also, if an animal moves into an environment in which they are at risk of being hunted themselves by another animal, this puts them at serious risk. And this is the same for the animals prey because if the animal goes into a new habitat lacking the things they usually eat, the animal will starve and in the long run, die out.

Answer 4

we cannot eat meats,eggs,cheese,milks and other products that made from animals.many products would be lost on the suppermarket because all animals will die.some people didn't eat vegetabes they eat only products made from animals they might die too if they dont eat vegetables.and zoo's will disappear too.
