Bottom-up regulation is defined as the size of predator and prey populations that is controlled by the scarcity of one or more resources.
The population size (number) of a predator species is directly controlled by the availability of a food source (prey). The more prey available, the greater growth in the number of predator species.
The population size of predator species is typically controlled by the availability of prey, competition with other predators, and environmental factors like habitat and climate. The population size can fluctuate based on these factors, leading to dynamic predator-prey relationships.
Animals of a species kill each other for food, water, shelter, etc. and the deaths keep the population from getting too high.

Because their new habitat lacks the parasites and predators that control their population "back home."
This the the short form of the species concept.So,Species.
People might use density-independent limiting factors, such as habitat modification or chemical control, to manage populations of introduced species because these methods can have a quick and direct impact on population size. They can help control invasive species that are causing harm to native ecosystems and species. Density-independent factors can be effective in reducing population levels without relying on natural predators or disease.
An introduced species is an animal species that people put into a habitat that they are not native to. For example cane toads were introduced to Australia from Central America to try to control the population of mice. As these "Brilliant" ideas usually do it failed now the cane toad population is out of control and killing the Australian Ecosystem because of the toad's incredible appetite.
Biological control refers to the use of natural enemies, such as predators, parasites, or pathogens, to manage the population of pest species. In the context of weeds and pests, it involves introducing or promoting these natural enemies in order to reduce the population of the targeted species. Biological control is a sustainable and environmentally friendly approach that can help to limit the use of chemical pesticides and herbicides.
The population of a species diminishes due to both abiotic and biotic factors. Abiotic factors like natural disasters, climate change, and habitat destruction can directly impact a population. Biotic factors, such as predation, competition for resources, and diseases, can also contribute to population declines.
Crocodiles are part of an ecosystem, and can be considered an apex predator. As a predator, they contribute to population control of prey species.
