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 herd of elephants that is excessively hunted by humans and is losing habitat to increasing farmland

a population of vernal pool fairy shrimp that grows rapidly during the wet season and then sharply declines during the dry season

a wolf population that has been established in an area for decades, with a stable but limited prey population

Explanation:

Logistic growth is when a population grows until it nears carrying capacity (limited by resources).

• Elephant herd: Hunted/losing habitat (not logistic, more like decline from external factors).
• Fairy shrimp: Seasonal (dry season decline, not resource - limited growth to carrying capacity).
• Wolf population: Established, prey (resource) is stable but limited. So wolf population approaches carrying capacity (prey limit), showing logistic growth.

Answer:

a wolf population that has been established in an area for decades, with a stable but limited prey population
