List the three types of symbiotic relationships.
mutualism, commensalism, and parasitism
Type of succession that occurs in an area in which the disturbance left the soil intact.
secondary succession
All of the living organisms interacting in a particular area is called a?
community
Give an example of an adaptation in predator species.
speed
heat sensitivity

Give two examples of adaptations in plant species that help them avoid predation by herbivores.
sharp spines
thorns
sticky hairs
tough leaves
poison
bad taste
Give an example of parasitism.
tape worms and humans
ticks and dogs
fleas and deer
This type of succession occurs in an area that was previously devoid of life.
primary succession
What is the end result of habitat destruction?
extinction
A defense in which one organism resembles another organism that is dangerous or poisonous.
Mimicry
The relationship between two different species in which one species captures, kills and consumes the members of the other species.
predation
A close and permanent relationship that exists between two different organisms.
symbiosis
What is the first type organism to appear after secondary succession?
grass
Larger areas usually contain more different species since a large area contains more different habitats in which species can live. What is the name of this principle?
species-area effect
Which type of adaptation allows organisms to blend into their environment?
camouflage
The struggle that occurs between organisms for the same limited resource is called?
competition
Humans and dogs is an example of which type of symbiotic relationship?
mutualism
An event that changes a community by removing organisms from it or altering resource availability is called a ___.
disturbance
No two species can occupy the same niche in the same habitat at the same time. This is known as?
competitive exclusion principle
Give an example of mimicry in nature.
Viceroy and monarch butterflies.
King and coral snakes.
Competition may be reduced when two similar species that require the same resource use only a part of the available resource. This phenomenon is known as
resource partitioning
Filter-feeding barnacles that live on the skin of a whale benefit from the flow of water over them. Which type of symbiosis is described?
