When a population grows past the ecosystem's carrying capacity, what happens to the population?

The population starts to die off to return to carrying capcity

The population will go extinct due to lack of resources

The population grows then finds a new carrying capacity

When a population has reached carrying capacity

Births & Immigration are equal to Death & emigration

Births & Immigration are less than Death & emigration

Births & Immigration are greater than Death & emigration

What does the term carrying capacity describe?

The population size that the environment can sustain.

The maximum number of birth rates for a population.

The ability of a population to accept new immigrants.

The ratio of birth rates to death rates in a population.

The lionfish is a venomous fish found primarily in the Red Sea and the Indian Ocean.

Which of the following scenarios is most likely to result in the lionfish having a major impact on the communities into which they were introduced?

With no natural predators, the lionfish population will become very large.

Some native species of invertebrates will develop a resistance to lionfish venom.

Random mating will allow the lionfish population to reach Hardy-Weinberg equilibrium.

A virus that specifically infects lionfish will become more prevalent.
