Carrying Capacity and Limiting Factors
Carrying capacity is defined as the number of organisms that an ecosystem can support. The carrying capacity is determined by limiting factors that determine the growth of populations within the ecosystem. Biotic limiting factors include
the availability of food and competition with other organisms. Abiotic limiting factors include space, temperature, and the availability of water. The carrying capacity and the limiting factors of an ecosystem are related. A population will
experience logistic growth due to limiting factors and experience exponential growth due to an absence of limiting factors, as shown in the graph.

The Sonoran Desert covers portions of Arizona, California, and Northwestern Mexico. The desert is rich in biodiversity and includes organisms such as desert cottontail rabbits, coyotes, birds, insects, reptiles, and many plant species.
While it is mostly hot and dry, it has two rainy seasons where it receives 3-20 inches of rain per year. The diagram shows a simple food web of an ecosystem in the Sonoran Desert.
