Question

logistic growth occurs whenever a populations size approaches its carrying capacity and is limited by resource availability.
which of these populations is most likely experiencing logistic growth?
a population of mosquitoes that grows rapidly during the summer and then sharply declines by the winter
a population of frogs that is declining due to an introduced disease
a stand of maple trees in a dense forest that compete for sunlight

Explanation:

To determine which population is experiencing logistic growth, we recall that logistic growth involves a population approaching its carrying capacity (limited by resources).

• The mosquito population has seasonal fluctuations (not resource - limited growth to carrying capacity).
• The frog population is declining (not growing towards carrying capacity).
• The maple trees in a dense forest compete for sunlight (a resource), so their growth is limited by resource availability as they approach the forest's carrying capacity for maple trees.

Answer:

a stand of maple trees in a dense forest that compete for sunlight
