**What does it mean when an animal "immigrates" into an area?**
=**[1]Immigration is the movement of individuals that move into an country or a state to stay for a while.[2] When animals come into an area and stay in the area for a long period of time is called immigration.[3]The act of moving to a new place to settle in the area. Why do animals immigrate? [4] animals immigrate because the new environment has more limiting factors. Organisims need limiting factors to survive. Limiting factors prevent a population from increasing in the size. [6] Animals can also immigrate into a new area for many reasons, some are limiting factors, carrying capacity, hunting and deforestation.** **The carrying capacity can go up or down depending on if the resources are available. If there are a lot resources then the carrying capacity would go up making a lot more animals wanting to immigrate to a new ecosystem because there are more resources for them. If there aren’t a lot of resources then animals wouldn’t want to immigrate to the new ecosystem because the animals need resources to live.** =
