When there are very few animals When there is not enough food When there are old animals When there is plenty of food 14 / 15 When does overpopulation happen? When a population gets larger than the carrying capacity When the population gets smaller than the biotic potential When a population gets smaller than the carrying capacity When the population gets larger than the biotic potential 15 / 15 The struggle between two or more species or individuals in an ecosystem that require the same resources, such as food, water, sun, or territory.
