Carrying capacity
the maximum population growth rate under ideal conditions
the change in the population size per individual per unit time
the maximum population size that can be supported by an ecosystem.
the members of a species that live in an ecosystem and have the potential to reproduce.
When does zero population growth take place?

Why is the life span of a bird with an eye disease most likely reduced?
The bird cannot mate.
The bird cannot find food or water.
The bird spreads the disease to others.
The bird cannot survive a temperature change.
If a bird has an eye disease, which is the possible reason for the quick spread of this disease?
an abiotic factor
a decreased food supply
increased population density
increased immunity
