Final answer:
The carrying capacity of a population is determined by both biotic and abiotic limiting factors.
Step-by-step explanation:
The carrying capacity of a population is determined by both biotic and abiotic limiting factors because these factors can affect the availability of resources necessary for the population to survive and reproduce. Biotic limiting factors include competition for food and space, predation, and disease. Abiotic limiting factors include factors like temperature, water availability, and nutrient availability. For example, a population of deer may experience biotic limiting factors such as competition for food from other herbivores, and abiotic limiting factors such as drought reducing the availability of water and food.
