Quick 10Q: Population Ecology

Front

What happens to population size as competition for resources increases?

Back

The population size decreases.

Front

What occurs to the growth rate as N approaches K?

Back

The growth rate decreases.

Front

If a population of fish is growing exponentially with a growth rate of 2.0 and a current size of 2,500, how many fish are added each year?

Back

5,000 fish.

Front

What does a negative r value indicate about population size?

Back

The population size will decrease.

Front

How are organisms distributed around a watering hole in the Savanna?

Back

Clumped distribution.

Front

Define carrying capacity (K) in population ecology.

Back

The maximum population size that an environment can sustain.

Front

What is exponential growth in a population?

Back

A growth pattern where the population size increases rapidly over time, typically when resources are abundant.

Front

What is logistic growth in a population?

Back

A growth pattern that starts exponentially but slows as the population approaches the carrying capacity.

Front

What is the significance of the intrinsic growth rate (r)?

Back

It represents the rate at which a population would grow under ideal conditions.

Front

What is density-dependent regulation in population ecology?

Back

Factors that affect population size in relation to the population density, such as competition and disease.
