POPULATIONS & COMMUNITIES REVIEW

The nonliving things within the environment. ABIOTIC FACTORS

The living things within the environment. BIOTIC FACTORS

Level of organization below community; a group of these form a community. POPULATIONS

Can you name one of the characteristics/factors used to study a population? • DENSITY • SIZE • SPACE

Can you name one of the characteristics/factors that determine an organism’s niche? • DIET • INTERACTION WITH OTHER ORGANISMS • MEANS OF GETTING FOOD

During predation, what do you call the organism that does the hunting? PREDATOR

What do you call two species of organisms that live in the same community and compete over resources? COMPETITORS

Can you give one example of an abiotic factor? • WATER • SUNLIGHT • OXYGEN (AIR) • TEMPERATURE (WEATHER/CLIMATE) • SOIL (LAND/TOPOGRAPHY)

The study of interactions that take place between organisms within their environment. ECOLOGY

A single individual from a population. ORGANISM

The biotic communities and the abiotic factors that affect them. . ECOSYSTEM

The contest among organisms to obtain the resources they need to survive and reproduce. COMPETITION

A symbiotic relationship that benefits both species. MUTUALISM

The physical location where an organism lives. HABITAT

Name for a species that is first to inhabit a new area primarily after a volcanic eruption. PIONEER

Type of ecological succession that begins in a place that does not have soil and has never supported living organisms. PRIMARY

In addition to sunlight and precipitation, what other abiotic factor affects plant growth? TEMPERATURE (WEATHER/CLIMATE)

Type of ecological succession that occurs in an area that has soil and was once the home of living organisms. SECONDARY

Any abiotic factor that restricts the number of individuals in a population. LIMITING FACTOR

The size of a population occupying an area of specific size. POPULATION DENSITY

The largest number of individuals an environment can support and maintain for a long period of time. CARRYING CAPACITY

The part of the Earth that supports living organisms; largest level of organization for life. BIOSPHERE

The feeding of one organism on another. PREDATION

The role of an organism in an ecosystem. NICHE

Type of relationship where one organism benefits and the other harms its host. PARASITISM

Any close relationship between two or more different species. SYMBIOSIS

A type of relationship where one partner benefits and the other is neither helped nor harmed. COMMENSALISM

Do you know the difference between abiotic and biotic factors? Can you give examples of each?

Do you know the difference between mutualism, parasitism, and predation? Can you give an example of each?

Can you compare/contrast primary and secondary succession?

It’s a new year. . . Resolve to study more and give nothing but your best! GOOD LUCK!!
