Final answer:
Factors like food supply, space, nutrients, water flow speed, and human activities like deforestation affect food availability and environment, leading to varying population dynamics.
Step-by-step explanation:
Various factors affect food availability, water, space, shelter, and the environment, significantly influencing population growth and resource use. Limiting factors, such as a low food supply and inadequate space, can directly affect birth rates, death rates, and migration patterns within populations. For instance, if a grassland ecosystem experiences a fire, the immediate food availability for herbivores would decrease. Similarly, an increase in atmospheric carbon dioxide affects the global temperature, which can alter ecosystems and the distribution of plant and animal species.
Human factors including land development, habitat destruction, and resource exploitation also play a significant role. For example, as the population increases, so does the demand for land, food, and water, leading to deforestation and habitat destruction. Abiotic factors, such as light, temperature, and water flow speed, also play a crucial role in the global distribution of species. Pollution, climate change, aquifer depletion, and availability of nutrients are additional limiting factors that can influence the environment and the organisms living within it.
