Ecosystem Flashcards
Energy pyramid
A model that shows the available amount of energy in each tropic layer in an ecosystem.
Food web
A model that shows many different feeding relationships among living things
Decomposer
Organisms witch carry out the process of decomposition by breaking down dead decaying organisms
Food chain
A model that shows one set of feeding relationships among living things
Coniferous
Plants that produce reproductive organs called cones
Consumer

Biome
A major ecological community such as grassland,tropical rain forest,or desert
Deciduous

Ecology

Cycle
a process that repeats (related word: cyclic)
Nitrogen cycle
a process in which nitrogen in the atmosphere enters the soil and becomes part of living organisms then eventually returns to the atmosphere
Biotic factors
are the living components of an ecosystem. They are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.
Water cycle
the continual movement of water between the land, ocean, and the air
Abiotic factors
DescriptionIn biology and ecology, abiotic components or abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Abiotic factors and the phenomena associated with them underpin all biology
Producer
an organism that makes its own food; an organism that does not consume other plants or animals
