Threatened species are plants and animals that are likely to become endangered within the foreseeable future throughout all or a significant portion of its range. One way to try to protect species is to focus on areas with high species diversity. Mice are able to reproduce when they are about one month old. As development brings people deeper into a species range, they may have more exposure to wild species. When a species population declines by at least 20 percent within five years or two generations, it is also classified as endangered.4) Population restrictionsA species is classified as endangered when its population is restricted to less than 250 mature individuals. These species can motivate the public to preserve biodiversity and contribute to conservation, Agreements under which property owners are allowed to harvest resources or develop land as long as habitat is conserved or replaced in ways that benefit resident endangered or threatened species in the long run. b) If the person could work with that efficiency, at what rate, in watts, would they have to shed waste heat to the surroundings?
