- trophic level
- the position of an organism in a food chain.
- ecosystem
- the physical and biological components of an environment considered in relation to each other as a unit.
- nitrogen cycle
- describes the transformations of nitrogen and nitrogen-containing compounds in nature.
- global warming
- The heating of our atmosphere, biosphere, and geosphere.
- food web
- describe the feeding relationships between species within an ecosystem.
- biogeochemical cycle
- pathway by which a chemical element or molecule moves through both biotic ("bio-") and abiotic ("geo-") compartments of an ecosystem.
- population
- is the collection of inter-breeding organisms of a particular species.
- primary succession
- first plant life, and occurs in an environment in which an area, devoid of vegetation and usually lacking soil, is deposited.
- autotroph
- is an organism that produces complex organic compounds from simple inorganic molecules using energy from light or inorganic chemical reactions.
- producer
- organism that creates its own food source.
- K strategist
- the organisms reproduction is constant.
- abiotic
- are non-living chemical and physical factors in the environment..
- consumer
- organism that eats and takes in nutrients.
- biotic
- are living factors in the environment.
- carbon cycle
- carbon is exchanged among the biosphere, geosphere, hydrosphere, and atmosphere of the Earth.
- energy pyramid
- graphical representation designed to show the biomass or productivity at each trophic level in a given ecosystem.
- greenhouse effect
- gases absorb thermal infrared radiation trap heat within the surface-troposphere system.
- climax community
- - the development of vegetation in an area over time - has reached a steady state.
- r strategist
- the ability to reproduce quickly.
- decomposer
- are organisms that consume dead organisms.
- secondary succession
- occurs on soil that previously supported vegetation before a disturbance destroyed the plant life.
- water cycle
- shows how water is transformed in the environment.
- food chain
- describe the feeding relationships between species within an ecosystem in a linear path.
- succession
- orderly changes in the composition or structure of an ecological community.
- pioneer species
- species which colonizes previously uncolonized land, usually leading to ecological succession.
- carbon dioxide
- one of the gases responsible for heating the atmosphere.
- ecology
- is the scientific study of the distribution and abundance of life and the interactions between organisms and their natural environment
- human activities
- things that people do that contribute to the warming of the earth.
- heterotroph
- is an organism that requires organic substrates to get its carbon for growth and development.
