Species Interactions
The 3 main types of species interactions that occur within a community.
What is competition, predation, & symbiosis
Relationships in which two species live closely together on a more or less permanent basis
What is symbiosis?
In parasitism, one organism is positively effected. The other organism has this type of impact.
What is negative?
One organism captures and feeds on another
What is predation?
The gradual, sequential change of species in an area over time.
What is succession?
“No two species can occupy the same niche in the same habitat at the same time.”
What is competitive exclusion principle?
This relationship has a positive effect on both individuals involved
What is mutualism?
The organism that is negatively effected in the relationship.
What is the host?
The organism being eaten by the predator.
What is the prey?
The 2 types of succession.
What is primary & secondary?
When a harmless species resembles a poisonous or distasteful species as a means of protection.
What is mimicry?
A tick on a dog.
What is parasitism?
(True or False) The parasite wants to kill the host immediately.
What is False?
The predator gains nutrients from the prey therefore gets a positive effect. The prey gets this kind of effect.
What is positive?
The pioneer species in secondary succession.
What are grasses?
5 things that species within a community compete for.
What is water, food, shelter, space, gases, sunlight, ect...?
A barnacle catching a ride on the back of a blue whale.
What is commensalism?
(True or False) Every organism on Earth can act as a host to parasites.
What is true?
List 3 Top predators in the temperate deciduous forest that we live in.
What is hawk, coyote, bobcat, ect...?
This type of succession takes the longest because there is no established soil.
What is primary?
Limiting factor such as natural disaster that effects the community regardless of the number of organisms in a community.
What is density-independent limiting factor?
The 3 types of symbiotic relationships.
What is mutualism, parasitism, & commensalism?
A parasite such as a heart worm that lives inside the host is known as this.
What is an endoparasite?
List 3 Predator adaptions that help them capture their prey.
What are speed, fangs, camouflage, webs, large canines, ect...?
The highest point that a community can reach in which it is stable & undergoes little to no changes
What is climax community?
