Levels of Organization
An individual living thing is called a _______.
Organism
Relationship where both organisms benefit.
Mutualism
What percentage of energy that moves to the next trophic level.
10%
The first species to colonize a barren area, like lichens.
Pioneer Species
The study of interactions between organisms and their environment.
ecology
A group of the same species living in the same area. example all deers in one area.
Population
One organism benefits while the other is harmed.
Parasitism
Most energy in an ecosystem is lost in this form.
Heat
Type of succession that begins in an area with no soil.
Primary
The role or "job" an organism has in its ecosystem.
Niche
All the different populations living together in an area.We see bears, deers, plants.
Community
An organism that is hunted and eaten by a predator.
Prey
Organisms that obtain energy by eating other living things.
Consumers
A stable, mature ecosystem that marks the end of succession.
Climax Community
Nonliving factors in an ecosystem, like sunlight or water.
abiotic factors
Living and nonliving factors interacting in an area.
Ecosystem
Relationship where one benefits and the other is unaffected.
Relationship where one benefits and the other is unaffected.
this diagram shows many connected feeding relationships.
Food Web
This is present in secondary succession but not primary.
Soil
The maximum population an ecosystem can support.
Carrying Capacity
All areas on Earth where life exists.
Biosphere
Organisms that feed on dead organisms rather than hunting.
Scavengers
The trophic level that always contains the most energy.
Producers
The reason why secondary succession occurs faster than primary.
Soil already exists
What would happen to consumers if all producers were removed.
They would die
