Ecosystem Flashcards
Environment
All living and non living things around an organism is its environment.
Adaptation
An adaptation is a structure of behavior that allows a species to survive and reproduce in its environment.
Species
Species have the same general physical characteristics and other adaptations.
Population
Each population contains all the organisms of the same kind of community.
Ecosystem
An area in which living and non living things interact.
Community
Organisms that live together in an ecosystem make up a community.
Niche
The role that each species plays in its community is its niche[ job]
Biotic

Abiotic

Food Chain
Food chains show how energy is passed from the sun, to the producers, from producers to consumers.

Energy pyramid
Is a model that uses a pyramid shape to show that the energy available for consumers decreases as it travels through a typical food chain or web.
Tertiary
This level is at the top of the food chain and it feeds on the secondary consumer.
10% rule
When energy is passed through an ecosystem.
Symbiosis
A relationship which two different organisms live in close association with each other.
