How Populations Survive Chapter 5, Lesson 3 limiting factor carrying capacity endangered species extinct threatened species

limiting factor – anything that controls the growth or survival of a population predators predators camouflage food sources

carrying capacity – the maximum population size that the resources in an area can support

endangered species – a species that is in danger of becoming extinct Click here to enter the link Click here to enter the link

extinct – a species that has died out completely Click here to enter the link Click here to enter the link

threatened species – a species that may become endangered

urban growth – the movement from a rural (country) area to an urban (city) area

pollution – when the air, water, or soil is dirtied by chemicals and/or trash

strip mining – when people carve the land to get rocks that are near the surface

fertilizer – chemicals used to make plants grow more effectively

agriculture – farming; cultivating or growing plants for food or to meet other needs and wants
