Limited Resources

A situation in an ecosystem where the availability of resources such as food, water, or territory is insufficient to fulfill the needs of all organisms competing for them.

Consumption Overpopulation

A situation where the level of consumption by a population exceeds the ecosystem's carrying capacity, leading to environmental degradation.

Interference Competition

A form of competition where individuals directly interact and inhibit each other's access to resources, often through aggressive or exclusionary behavior.

Exploitation Competition
