Question Answer What is a habitat? An environment that provides food, water, shelter, and other things an organism needs to live, grow and reproduce. What is an organism? A living thing. What is a biotic factor? The living parts of a habitat. What is an abiotic factor? The non-living parts of a habitat (water, sunlight, oxygen, temperature, soil) What is a species? A group of organisms that are physically similar and can mate and reproduce with each other What is a population? A group of organisms in a particular area What is a community? All the different populations that live together in an area. What is an ecosystem? The community of organisms that live in a particular area, along with the abiotic factors What is ecology? The study of how living things interact with each other and the environment What is immigration? Moving into a population. What is emigration? Moving out of a population. What is population density? The number of individuals in an area of a specific size. What is a limiting factor? An environmental factor that causes a population to decrease. What is a carrying capacity? The largest population that an area can support. What is natural selection? A process by which characteristics that make an individual better suited to its environment become more common in a species What is adaptation? A behavior/physical characteristic that allows an organism to live successfully in its environment.
**The way animals "change" to survive in their habitat. What is a niche? The role of an organism in its habitat. What is competition? The struggle between organisms to survive as they attempt to use the same limited resource What is predation? An interaction in which one organism kills another for food.
**Predator hunts for their food What is symbiosis? A close relationship between two species that benefits at least one What is mutualism? A symbiotic relationship in which both benefit
**mutual means "share… you both get something" What is commensalism? A symbiotic relationship in which one species benefits and the other is neither helped nor harmed What is parasitism? A relationship that involves one organism (the species) living on or inside another organism (host) and harming it.
Example: tick on dog What is succession? The series of predictable change that occurs in a community OVER TIME What is PRIMARY succession? The series of changes that occur in an area where NO soil or organisms exist. What is a pioneer species? The first species to populate an area.
**Pioneer means "first" like the Pioneers who were the first people to live in North America. What is SECONDARY succession? The series of changes that occur in an area where the ecosystem has been disturbed, but where soil and organisms still exist. What is a habitat?
