Kelli's Mind Map Vocab Project

Trophic levels

The energy levels or steps in a food chain or food web


Group of living organisms that interact with one another and the non living physical enviorment as one unit

Organism, Any form of life

Community, Population of living organism that interact with one another in an ecosystem

Population, A group of organisms of the same species inhabiting a given area

Biosphere, Layers of soil, water, and air that substains life

Biome, Geographic region of earth that is inhabitied by a community of distinct types of plant and associated animal species

Food Webs, representations of the predator-prey relationships between species within an ecosystem or habitat, Food Chain, •The sequence of who feeds on or decomposes whom in an ecosystem

Producer, The organisms that produce their own energy, Consumer, Primary Consumer, Eats producers, Secondary Consumer, Eats primary consumer, Tertary Consumer, Eats Secondary Consmer


the variation of life forms within a given ecosystem, biome, or for the entire Earth


a forest with heavy annual rainfall

Temperate deciduous forest

consists of trees that lose their leaves every year

Coniferous forest

A forest consisting mostly of conifers such as firs, pines and spruces, usually in climates too dry or too cold to support deciduous forest.


areas with an average annual precipitation of less than per year, or as areas where more water is lost by evapotranspiration than falls as precipitation


a vast treeless plain in the Arctic regions where the subsoil is permanently frozen


a grassland ecosystem characterized by the trees being sufficiently small or widely spaced so that the canopy does not close

Freshwater biome

The aquatic biome consisting of water containing fewer salts than the waters in the marine biome

Marine biome

all the water that is on the earth's surface

Biotic factors

the factors in a biome/ecosystem/habitat that include all living things

Abiotic factors

components are non-living chemical and physical factors in the environment

Hot spots

Streams of molten rock arise deep inside the Earth and move upward through the crust to erupt on the surface or seafloor

Ecological succession

the gradual and orderly process of change in an ecosystem brought about by the progressive replacement of one community by another until a stable climax is established

Primary succession

plant life, occurring in an environment in which new substrate devoid of vegetation and usually lacking soil

Secondary succession

a process started by an event that reduces an already established ecosystem

Pioneer species

- the first organisms to start the chain of events leading to a livable biosphere or ecosystem

Climax community

a biological community of plants and animals which, through the process of ecological succession — the development of vegetation in an area over time

Limiting factors

condition of the environment that limit the growth of species

Carrying capacity

the number of individuals of a species that an ecosystem can support

Population growth

increase in the number of people who inhabit a territory or state

Black Plague

killed off most people in 1400

Industrial Revolution

the world population went up in 1800

Exponential growth

occurs when the growth rate of a mathematical function is proportional to the function's current value


how biological systems remain diverse and productive over time

Logistic growth

Growth rates regulated by internal and external factors that establish an equilibrium with environmental resources


a graph representing exponential population growth.


the rate of growth is rapid and then the growth rate declines

Population growth rate

the change in a population over time

Water pollution

contamination of water, especially surface water, by sewage effluent, fertilizer runoff, industrial chemical discharge

Point source

pollution that comes from a single source

Non-point source

pollution that comes from a combination of town residents going about their everyday activities


underground bed or layer yielding ground water for wells and springs
