Why can two species with identical niches struggle to coexist?
They compete for the same limited resources.
Why does population growth slow as it approaches carrying capacity?
Resources become limited, increasing competition and reducing growth.
What is the difference between intraspecific and interspecific competition?
Intraspecific occurs within one species; interspecific occurs between different species.
How can a decrease in rainfall affect an ecosystem?
Less water can reduce plant growth and affect animal populations.
