Cycles of Nature

Cycles of Nature/Levels of Ecology

TermDefinition
Biogeochemical Cycle the circulation of substances through living organisms from or to the environment
Biomass organic matter that can be a source of energy; the total mass of the organisms in a given area
Carnivore an animal that eats other animals
Condensation the change of state from a gas to a liquid
Conservation of Mass and/or Energy The principle stating that matter(energy) is not created or destroyed during a chemical reaction.
Decomposer an organism that feeds by breaking down organic matter from dead organisms; examples include bacteria and fungi
Energy Pyramid a triangular diagram that shows an ecosystem's loss of energy, which results as energy passes through the ecosystem's food chain; each row in the pyramid represents a trophic (feeding) level in an ecosystem, and the area of a row represents the energy stored in that trophic level
Food Chain the pathway of energy transfer through various stages as a result of the feeding patterns of a series of organisms
Food Web A diagram that shows the feeding relationships between organisms in an ecosystem.
Herbivore an organism that eats only plants
Omnivore an organism that eats both plants and animals
Transpiration the process by which plants release water vapor into the air through stomata; also the release of water vapor into the air by other organisms
Biosphere the part of Earth where life exists; includes all of the living organisms on Earth
Eutrophication A process by which nutrients, particularly phosphorus and nitrogen, become highly concentrated in a body of water, leading to increased growth of organisms such as algae or cyanobacteria., When the plants and algae die, bacteria break them down. The bacteria use oxygen to do this and the oxygen levels go down. Animals and other organisms that live in the water die from lack of oxygen.
Abiotic Any nonliving component of an environment
Biotic Describes living factors in the environment.
Trophic Levels one of the steps in a food chain or food pyramid; examples include producers and primary, secondary, tertiary, and quaternary consumers
Primary Consumer Second level of a food chain/food/energy pyramid, made up of Herbivores
Secondary Consumer Third level of a food chain/food/energy pyramid, made up of carnivores or omnivores.
Tertiary Consumer Fourth level of a food chain/food/energy pyramid, can be made up of carnivores or omnivores.
Quaternary Consumer Fifth level of a food chain/food/energy pyramid, can be made up of carnivores or omnivores.
