Front

What is logistic growth in population ecology?

Back

Logistic growth is a model of population growth that describes how a population grows rapidly at first, then slows as it approaches the carrying capacity of its environment.

Front

What is mutualism in ecology?

Back

Mutualism is a type of symbiotic relationship where both species benefit from the interaction, such as alligators and birds.

Front

Define biosphere.

What is transpiration in plants?

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.

Front

What is the difference between exponential growth and logistic growth?

Back

Exponential growth occurs when resources are unlimited, leading to a rapid increase in population size, while logistic growth accounts for environmental limits.

Front

What is commensalism?

Back

Commensalism is a type of symbiotic relationship where one species benefits and the other is neither helped nor harmed.

Front

What is parasitism?

Back

Parasitism is a relationship where one organism benefits at the expense of another, often harming the host.
