What type of interaction is it when both foxes and coyotes in an area feed primarily on a limited supply of rabbits?

• Mutualism

• Parasitism

• Commensalism

• Competition

What is a limiting factor in an ecosystem?

• A factor that promotes unlimited growth of populations

• A resource or condition that restricts the growth, abundance, or distribution of organisms .

• A factor that has no impact on the population size

• A resource that is abundantly available to all organisms

Which factor can cause a decrease in a population's size?

• An increase in food supply

• Decreased competition for resources.

• An increase in predation

• Improved weather conditions

Which of the following best describes ecological competition?

• A mutual benefit between two different species that share resources.

• A relationship where one species benefits at the expense of another.

• A scenario where species harm each other while trying to harm themselves.

• A situation where different species vie for the same resource that is in short supply.

Fluctuations in population can correlate to change in ___

• Predation.

• Weather.

• Resource availability.

• Parasitism.

Which of the following best describes classical conditioning?

• The gradual strengthening of stimulus-response connections that seemingly are unrelated.

• A type of associative learning in which there is no contingency between the response and re-enforcer.

• Learning behavior in which an organism follows the first moving objects it encounters.

• Learning behavior in which an organism exhibits a fixed action pattern from the time of birth.

What happens in classical conditioning?

• An animal learns to perform a behavior for a reward.

• A neutral stimulus becomes associated with an unconditioned stimulus to elicit a conditioned response.

• An organism learns to avoid a certain behavior based on negative consequences.

• An organism learns a new behavior through observation and imitation.

Which is the correct sequence of events during primary succession?

• low shrub -high shrub -grass -shrub -tree -low tree -high tree

• high shrub -low shrub -grass -low tree -high tree -shrub -tree

• grass -shrub -tree -high tree -low tree -low shrub -high shrub

• grass -low shrub -high shrub -shrub -tree -low tree -high tree

Which event is most likely to initiate secondary succession?

• The formation of a new volcanic island.

• The melting of glaciers exposing bare rock.

• A wildfire burning a forested area.

• The drying up of a riverbed.
