what is primary succession
the forming of a community in a area that has not ever been occupied.
what is secondary succession
recovery of an old ecosystem.
what is a predator?
organisms hunting or killing another for food
what is competition
the relationship between two or more organisms that are fighting for the same limited resource.
what is symbiosis?
any interaction involving a close, physical, long term relationship between two species.
what is a pioneer species?
The first organism to grow in a new environment.
what could cause secondary succession to occur?
natural disturbance/disaster or farming
organism being consumed or killed as food.
what is interspecific competition
competiton between different species
one organism benefits while others are unaffected.
towards the end of succession.
what is an example of a pioneer species in secondary succession?
weeds or grasses
what is a keystone species
it is a species that holds the ecosystem together.
what is intraspecific competition?
competition between the SAME species
what is symbiosis Mutualiam?
both organisms involved benefit and helps both survive
what are two example of a pioneer species?
Lichens and mosses
what is the result of secondary succession?
mature and stable climax community.
what is an example of prey for a linx?
Rabbit
what is a competitive exclusion principal?
no two organisms can occupy the same niche at the same time.
What is symbiosis parasitism?
when one organism (parasite) benefits from the relationship while the other (host) is harmed
what is the result of primary succession?
A mature and stable climax community.
how does secondary succession affect the ecosystem?
by enhancing the overall diversity and complexity of an ecosystem.
When the prey population decreases what happens to the predator population.
the predator population decreases
what is a Niche?
all the things an organism needs and does within its habitat.
is symbiosis inta- or inter-specific?
Always interspecific
