Lucas's Mind Map Vocab Project

Food Chain - a succession of organisms in an ecological community that constitutes a continuation of food energy from one organism to another.

Trophic Levels - the positions organisms occupy on a food web.

Producers - organisms that produce their energy from the sun., Primary Consumers - an organism that gets its energy from eating producers., Secondary Consumers - organisms that get their energy by eating primary consumers., Tertiary Consumers - organisms that get their energy from eating secondary consumers.

Food Web - a complex of interrelated food chains in an ecological community.

New node


Organism - any form of life.

Biome - a region of earth inhabited by a community., Biosphere - layers of soil, water, and air that sustains life., Ecosystem - a group of organisms that interact with each other and the enviornment., Community - populations of organisms that interact in an ecosystem., Population - a group of the same species in the same area at a given time.

Earth's Regions

Tundra - a biome where plant life is hindered by low temperatures and short growing seasons.

Desert - a landscape or region that recieves an extremely low amount of precipitation, less than enough to support growth of plants., Temperate deciduous forest - a forested biome found in mid-latitude temperatures and dominated by deciduous vegetation., Rainforest - forests characterized by high rainfall, with diverse plant and animal life., Grassland/Savannah - a grassland ecosystem characterized by the trees being small or widely spaced enough so that the canopy does not close., Coniferous Forest - a terrestrial biome found in temperate regions of the world with warm summers and cool winters and adequate rainfall to sustain a forest.


Marine Biome - an aquatic biome that includes all the water on the earth's surface. It covers 3/4 of the earth.

Freshwater Biome - a low-saline aquatic biome thata ccounts for 1/5 of the earth's surface., Aquifer - a geological formation that contains water., Water Pollution - the contamination of water bodies., Point Source - where water pollution is caused by a single identifyable source., Non-pont Source - where water pollution is caused by many sources together.

Biodiversity - the degree of variation of life forms within a given ecosystem, biome, or planet.

Hotspots - a region of the earth which is extremely biologically diverse, and under severe threat due to habitat loss.

Biotic Factors - living factors in an ecosystem., Abiotic Factors - non-living factors of anecosystem that affect living organisms.

Ecological Succession - a series of enviornmental changes thta occurs in stages. At each stage, differnt species of plants and animals may be present.

Primary Succession - succession that occurs in places that an ecosystem has never existed.

Secondary Succession - succession that occurs in places where an ecosystem has been damaged., Pioneer Species - the first species to move into an ecosystem at the beginning of succession, Climax Community - a community at the end of succession that is in equilibrium with little or no change in species.

Population Growth - the change in a population over time.

Limiting Factors - a factor that controls a process, such as organism growth or species population, size, or distribution.

Carrying Capacity - the maximum population size of a species that an enviornment can sustain indefinitely., Exponential Growth - when a population has a constant birth rate through time and is not limited., Sustainability - when a population has the capacity to endure over time., Logistic Growth - growth in a population with limited resources and space., J-curve - when on a graph, the population curve initially falls, then rises to above where it started., S-curve - A pattern of growth in which, in a new environment, the population density of an organism increases slowly initially, then increases rapidly approaching an exponential growth rate; but then declines in a negative acceleration phase until the population balances out., Population Growth Rate - the rate at which a population changes over time.


Black Plague - a bubonic plage that kiled 3 million people in the 1300's. This made the population go down.

Industrial Revolution - a period in the 18th - 19th centuries where technology greatly increased, allowing the human population to increase as well.
