carrying capacity

population crash

lag phase

mutualism

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

Continues to grow

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

Which is NOT a reason for the decreasing death rate?

Better health care

Greater food supply

Cleaner water

More pollution

What might happen if the earth exceeds its carrying capacity?

There might not be room for people to move around.

There might not be enough food and water for everyone.

The continents might sink into the oceans.

Most of the people on the planet would starve.

Why would advances in medicine lead to population growth?

Curing deadly diseases allows people to live longer

People are unable to have babies without medical help

Babies do not grow if they don't take their medicine

New drugs allow mothers to have multiple births, like octuplets
