Question

1. what circumstances could limit the growth of populations of organisms? provide a 2-3 sentence explanation.

Explanation:

Resource scarcity, such as limited food, water, or habitat space, directly restricts population growth by reducing the number of individuals an environment can support. Additionally, biotic factors like predation, competition for resources, and disease can control population sizes by increasing mortality or reducing reproductive success. Abiotic factors including extreme temperatures, natural disasters, and pollution also limit growth by making habitats uninhabitable or stressful for organisms.

Answer:

Population growth can be limited by resource scarcity (like insufficient food, water, or living space) that caps the carrying capacity of an environment, biotic pressures such as predation, interspecies competition, and infectious diseases that raise death rates or lower reproduction, and abiotic stressors including extreme weather, natural disasters, and pollution that degrade habitat suitability.
