Unit 2 (Flashcard 4): Pulse Check - 24

Front

What is the term for competition between members of the same species?

Back

Intraspecific competition.

Front

What happens to a population when it exceeds the ecosystem's carrying capacity?

Back

Density dependent limiting factors occur, causing the population to decrease back below carrying capacity.

Front

What type of symbiotic relationship occurs when one organism benefits at the expense of another?

Back

Parasitism.

Front

What is the relationship called when tapeworms absorb nutrients from their host's intestines?

Back

Parasitism.

Front

What phenomenon occurs when two species compete for the same resources and one species outcompetes the other?

Back

Competitive exclusion.

Front

Define carrying capacity in an ecosystem.

Back

The maximum population size of a species that an environment can sustain indefinitely.

Front

What are density dependent limiting factors?

Back

Factors that affect population size in relation to the population's density, such as food availability, disease, and predation.

Front

What is the difference between intraspecific and interspecific competition?

Back

Intraspecific competition occurs between members of the same species, while interspecific competition occurs between members of different species.

Front

Give an example of a parasitic relationship in nature.

Back

Mistletoe extracting water and nutrients from a spruce tree.

Front

What is the significance of competitive exclusion in ecology?

Back

It explains how two species competing for the same resources cannot coexist indefinitely; one will outcompete the other.
