Ecosystems
Living factors in an ecosystem.
What is a biotic factor
When energy and matter flows in and out of an ecosystem.
Open System
Organisms that make their own food.
Producers
Process in which producers produce food
Photosynthesis
When a new species enters and uninhabited area.
Pioneer Species
Non Living factors in an ecosystem
Abiotic
When energy can flow in and out, but matter cannot in an ecosystem
Closed System
Organisms that rely on eating to obtain energy.
Consumers
Process in which consumers use to create energy.
Cellular Metabolism
When a community reaches its final, most stable, state.
Climax Community
DOUBLE JEOPARDY
Give two biotic factors and how they effect the ecosystem
Shows energy flow in an ecosystem
Food Chain
Organisms that only eat plants.
Herbivores
Molecule that cycles through plants and animals to create proteins, fats, and carbohydrates.
Carbon
When life enters an area that previously did not support life
Primary Succession
DOUBLE JEOPARDY
Give two abiotic factors and how they effect the ecosystem
Amount of energy transferred when a consumer consumes.
10%
Organisms that eat plants and animals
Omnivore
Molecules that need to be altered in order to be used by organisms to create proteins.
Nitrogen
When new life enters an area that previously had life
Secondary Succession
Five things that are required for life to exist
Energy, CO2, O2, H2O, Gravity
Each level of a food chain
Trophic Level
Organisms that break down dead organisms.
Decomposers
Molecule commonly found in fertilizers that can cause large algae blooms.
Phosphorus
Gradual process of change and replacement of some or all species in a community
