Question

what is the definition of a limiting factor?
a factor that limits populations from growing forever.
a factor that allows populations to grow without limits
a factor that limits the food a population can get.
a factor that limits the oxygen a population can get.

Explanation:

A limiting factor is a resource or environmental condition that restricts the growth, distribution, or abundance of an organism or a population within an ecosystem. It prevents populations from growing indefinitely. The option "A factor that limits populations from growing forever" aligns with this general ecological concept. The other options are too narrow (limiting only food or oxygen) or incorrect (allowing unlimited growth).

Answer:

A factor that limits populations from growing forever.
