What is carrying capacity (K) in a population?

Back

The maximum number of individuals of a species that an environment can support sustainably.

Front

What is the formula for calculating population growth?

Back

Population Growth = r * N * (1 - N/K), where r is the growth rate, N is the current population size, and K is the carrying capacity.

Front

What does a growth rate (r) of 1.05 indicate?

Back

It indicates a 5% increase in the population size per time interval.

Front

How does the cytoskeleton contribute to cell movement?

Back

Its dynamic nature allows for the reorganization of the cytoskeleton, facilitating cell movement and providing structural support.

Front

What is primary succession?

Back

The process of ecological change that occurs in an area where no soil exists, starting from bare rock.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts from bare rock, while secondary succession occurs in areas where soil exists but the ecosystem has been disturbed.

Front

What is the significance of population density in ecology?

Back

Population density affects resource availability, competition, and the overall health of an ecosystem.

Front

What is the role of parasites in population dynamics?

Back

Parasites can decrease the population density of their hosts by causing disease and mortality.

Front

What is the formula for calculating population growth rate?

Back

Population Growth Rate = (Births - Deaths) / Total Population.

Front

What is a climax community?

Back

A stable and mature ecological community that has reached the final stage of ecological succession.
