Focuses on how organisms respond to abiotic environmental challenges through regulation, conformity, migration, or suspension.
Population dispersion is influenced by resource availability, determining whether individuals are clumped, uniform, or randomly distributed.

Humans exhibit a Type I survivorship curve, where mortality is low in early and middle life but increases in old age.

Tigers regulate prey populations and maintain ecosystem balance, making them keystone species.

An invasive species is one that is introduced into a new habitat and spreads aggressively, often harming native species.

Mutation affects genetic variation but does not directly influence population growth like natality, mortality, and migration.

r-selected species, like bacteria, reproduce rapidly with little parental care, while K-selected species, like elephants and whales, have slower reproduction.

Food availability depends on population density, whereas natural disasters are density-independent factors.

Invasive species can significantly alter ecosystem stability by reducing biodiversity and changing food web dynamics.

The carbon cycle occurs in both terrestrial and aquatic ecosystems, involving biological, geological, and chemical processes.

Predation helps regulate prey populations and maintain ecological balance, preventing overpopulation.

Density-dependent factors, such as disease, increase in effect as population density rises.

Biotic potential refers to the maximum reproductive capacity of a species under optimal conditions.
