DEBio 45 Population Ecology quizs

parasitism

• one organism benefits and the other is harmed

• both organisms benefit

• neither organism is affected

• both organisms are harmed

r-selected

• organisms that reproduce early in life, quickly producing large numbers of offspring that are usually small and short-lived

• organisms that reproduce later in life, producing fewer offspring that are usually larger and longer-lived

• organisms that have a stable population size and produce offspring at a constant rate

• organisms that invest heavily in parental care and produce few offspring

quadrat

• A type of geometric shape used in art.

• A square frame used for sampling in field work.

• A mathematical term for a four-sided figure.

• A tool for measuring angles in construction.

mutualism

• both organisms benefit

• one organism benefits while the other is harmed

• both organisms are harmed

• neither organism is affected

innate behavior

• a behavior that is inherited rather than learned.

• a behavior that is learned through experience.

• a behavior that is influenced by environmental factors.

• a behavior that is temporary and situational.

symbiosis

• relationship in which two species live closely together

• a competition between two species for resources

• a predator-prey interaction

• a random occurrence of species cohabitation

keystone species

• a species that influences the survival of many other species in an ecosystem

• a species that is the most abundant in an ecosystem

• a species that has no predators

• a species that migrates seasonally

pioneer species

• the first species to populate an area

• the last species to leave an area

• a species that thrives in extreme conditions

• a species that is commonly found in urban areas

carrying capacity

• largest population that an area can support

• the maximum number of species in an ecosystem

• the total biomass of an area

• the number of individuals in a population at any given time

K-selected

• organisms that reproduce later in life, produce fewer offspring, and devote significant time and energy nurturing their offspring

• organisms that reproduce early in life, produce many offspring, and provide little to no parental care

• organisms that reproduce at a constant rate throughout their lifespan and have a high survival rate

• organisms that reproduce in large numbers but have a high mortality rate among offspring
