What is a "keystone species"

an organism that the ecosystem doesn't need and only causes harm to other organisms

an organism that creates new ecosystems

an organism that opens doorways

an organism that the ecosystem depends on; without it, the ecosystem might collapse

influence an individuals ability to survive not based on the size of a population

influence an individuals ability to survive based on the size of a population

1

Exponential growth describes which of the following scenarios?

a population grows slowly, nears a carrying capacity, and stabilizes

a population grows slowly, hits carrying capacity and crashes

a population grows rapidly, nears a carrying capacity, and stabilizes

a population grows rapidly, hits carrying capacity and crashes

1

Age structure diagrams show us population based on which of the following?
