Ecosystems
Environmental changes such as availability of resources, changes in predation pressure, or disease outbreaks can affect the carrying capacity of a population by either increasing or decreasing the amount of resources available for the population to survive and reproduce.

Once limiting factors cause a population to slow its growth, a J curve transitions into an S curve, also known as logistic growth. In this phase, the population growth rate decreases as it approaches the carrying capacity of the environment. As resources become limited, factors such as competition, predation, and disease begin to play a more significant role, stabilizing the population size. Ultimately, the population fluctuates around the carrying capacity rather than continuing to grow exponentially.
Carrying capacity is the maximum number of individuals that an environment can sustainably support. If a population exceeds the carrying capacity of its environment, resources like food, water, and shelter become limited, leading to competition, scarcity, and population decline through factors like starvation, disease, or migration.
After a population reaches its carrying capacity, factors such as competition for resources, increased susceptibility to diseases, and environmental degradation can lead to decreased reproduction rates, increased mortality, and overall population decline. This can create a cycle of fluctuations around the carrying capacity as the population responds to these constraints.
Environmental change can lower carrying capacity by reducing available resources like food and water, increasing competition among species. It can also directly impact the habitat suitability for certain species, making it harder for them to thrive and survive. Overall, environmental change can lead to a decrease in carrying capacity for a given ecosystem or population.
Food availability, water, environmental conditions, and space. These are the most basic factors. Some species like human have much more complex factors like health resources and sanitation just to name a few.
