Carrying Capacity

The carrying capacity of a biological species in an environment is the population size of the species that the environment can sustain indefinitely, given the food, habitat, water and other necessities available in the environment.

Marine Biome

Growth whose rate becomes ever more rapid in proportion to the growing total number or size


a system formed by the interaction of a community of organisms with their physical environment


the regions of the surface and atmosphere of the Earth (or other planet) where living organisms exist


a major biotic community characterized by the dominant forms of plant life and the prevailing climate

Food Web

A system of interlocking and interdependent food chains


Producers - An autotroph is an organism that produces complex organic compounds (carbohydrates, fats, and proteins) from simple inorganic molecules using energy from light (by photosynthesis) or inorganic chemical reactions.

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.


A group of people living together in one place, esp. one practicing common ownership

Primary Consumer

A vegetarian organism in the second level of a food chain that feeds off the plants in the first level.

Tertiary Consumer

a high-level consumer, which is usually the top predator in an ecosystem and/or food chain.

Secondary Consumer

a consumer that gets its energy from other consumers. These are often called carnivores.


An individual animal, plant, or single-celled life form


Rainforests are forests characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1750–2000 mm (68-78 inches). The monsoon trough, alternately known as the intertropical convergence zone, plays a significant role in creating Earth's tropical rain forests.

Trophic Levels

The trophic level of an organism is the position it occupies on the food web. The word trophic derives from the Greek τροφή (trophē) referring to food or feeding. A food chain represents a succession of organisms that eat another organism and are, in turn, eaten themselves.

Temperate Deciduous Forest

A temperate deciduous forest is a biome found in the eastern and western United States, Canada, central Mexico, South America, Europe, China, Japan, North Korea, South Korea and parts of Russia.


A dry, barren area of land, esp. one covered with sand, that is characteristically desolate, waterless, and without vegetation


A vast, flat, treeless Arctic region of Europe, Asia, and North America in which the subsoil is permanently frozen

Food Chain

A hierarchical series of organisms each dependent on the next as a source of food


A particular section, group, or type of people or animals living in an area or country


land where grass or grasslike vegetation grows and is the dominant form of plant life

Freshwater Biome

The aquatic biome consisting of water containing fewer salts than the waters in the marine biome; divided into two zones: running waters (rivers, streams) and standing waters (lakes, ponds).

Biome Regions

An area of large amount of plants and animals in a distinct location.

Biotic Factors

A biotic factor is any living component that affects another organism, including animals that consume the organism in question, and the living food that the organism consumes.

Exponential Growth

Growth whose rate becomes ever more rapid in proportion to the growing total number or size

Secondary Succession

Secondary succession is one of the two types of ecological succession of plant life. As opposed to primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane) that reduces an already established ecosystem

Primary Succession

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.


Sustainability is the capacity to endure. In ecology the word describes how biological systems remain diverse and productive over time.

Pioneer Species

Pioneer species are species which colonize previously uncolonized land, usually leading to ecological succession.

Industrial Revolution

The rapid development of industry that occurred in Britain in the late 18th and 19th centuries, brought about by the introduction of machinery. It was characterized by the use of steam power, the growth of factories, and the mass production of manufactured goods

Ecological Succession

Ecological succession, a fundamental concept in ecology, refers to more or less predictable and orderly changes in the composition or structure of an ecological community.

Logistic Growth

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

Climax Community

n ecology, a climax community, or climatic climax community, is a biological community of plants and animals which, through the process of ecological succession — the development of vegetation in an area over time — has reached a steady state

Black Plague

Also known as The Black Death, the Black Plague was one of the deadliest pandemics in human history, peaking in Europe between 1348 and 1350. It is widely thought to have been an outbreak of bubonic plague caused by the bacterium Yersinia pestis, but this view has recently been challenged.  

Hot Spots

A small area or region with a relatively hot temperature in comparison to its surroundings

Limiting Factors

A factor or limiting resource is a factor that controls a process, such as organism growth or species population, size, or distribution. The availability of food, predation pressure, or availability of shelter are examples of factors that could be limiting for an organism.


The variety of life in the world or in a particular habitat or ecosystem


A curve that the rate of growth is rapid and then the growth rate declines. This produces a curve that appears as an S, due to a slow start, rapid growth, then leveling.

Abiotic Factos

Abiotic factors are the nonliving components of the biosphere.

Population Growth Rate

Population growth is the change in a population over time, and can be quantified as the change in the number of individuals of any species in a population using "per unit time" for measurement.

Population Growth

Population growth is the change in a population over time, and can be quantified as the change in the number of individuals of any species in a population using "per unit time" for measurement.


The term J-curve is used in several different fields to refer to a variety of unrelated J-shaped diagrams where a curve initially falls, but then rises to higher than the starting point.

Water Pollution

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

Non-Point Source

A source of pollution that issues from widely distributed or pervasive environmental elements


underground bed or layer yielding ground water for wells and springs etc

Point Source

A source of energy, such as light or sound, that can be regarded as having negligible dimensions
