That would be a physical change
Answer: 1
Homeostasis in terms of temperature within the human body is achieved by reaction to stimulation from the environment. For example, in cold temperatures our bodies shiver to get warm.
Tectonic plates are the result of the mantle cooling on the surface. At plate boundaries or "zones" occure, there are different reactions along the edges of them. Divergent is when two plates move away from one another allowing fresh molten rock to flow to the surface. This results in a volcano. Covergent boundaries are when plates come together, resulting in mountain ranges. Transforming boundaries are when they slide up against each other causing earthquakes. More examples of proof of plate tectonics is the changing of Pangea into the world as we know it and subduction zones that reveal fossils that were deeply buried under layers of earth.
The answer is there are few effective predators of rabbits.
When a new species is introduced into some area, it could very soon increase its population size if there are no natural predators. Predators maintain prey population on some optimal size and that way homeostasis in ecosystem is achieved. Without natural predators, rabbit population will increase its size. With more rabbits in the area, many native species will decrease their population size because they must compete with rabbit population for resources.
