Detailed explanation-1: -If a population exceeds carrying capacity, the ecosystem may become unsuitable for the species to survive. If the population exceeds the carrying capacity for a long period of time, resources may be completely depleted. Populations may die off if all of the resources are exhausted.
Detailed explanation-2: -How would a sudden increase in parasites, within a population, affect the population’s growth? The death rate would increase.
Detailed explanation-3: -Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
Detailed explanation-4: -Catastrophic events, such as deadly hurricanes, tornadoes, forest fires, or floods, can decrease biodiversity by killing a species or harming an ecosystem. Human activity can also cause a loss of biodiversity by displacing species from their natural habitat or killing organisms.
