The Florida Panther is a large cat that is native to the southern parts of Florida. Recently, the panther's main food source, rabbits, have been infected with a deadly disease that only affects rabbits. How would this most likely affect the population of panthers in the coming years?
The panther population will decrease since they won't have access to as much food
The panther population will not be affected because they will adapt to eating other food
The panther population will increase because they will produce more offspring to make up the difference
The panther population will decrease because they will contract the disease.

air
bacteria
water

When a population goes over the carrying capacity this is known as
oscillation
overshoot
dieback
exponential
A species that plays a critical role in the health, maintenance, growth, or definition of an ecosystem.
keystone
invasive
engineer
predator
Why are bees considered a keystone species?
The honey they make supports the bear population
They pollinate flowers that produce fruit which supports the ecosystem
They sting when threatened
They live in hives
