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.

How can a new species with no predator affect other populations of species?
Their population could grow much faster, and they could compete with other species for food.
How will the size of a predator population affect the numbers of prey?
This will depend on the specific ecosystem and the specific predator and prey relationship being examined within that ecosystem. If, as an oversimplified example, a drought caused a reduction in edible plant foods for a prey animal, the population of said prey animal may decrease. If the prey population decreased, there would not be enough food to support the current predator population, and a number of the predators would die until a balance was reached.The overall idea is fairly simple, however. If weather conditions are favorable to the increase of the population of a prey species, then the prey species's population will increase, all other things being equal. When the population of a prey species increases, then more of the offspring of the predator species can survive, allowing the population of the predator to increase. If weather somehow decreases the population of a prey animal, then this will also reduce the population of the predator species, all other things being equal.It is important to remember, however, that ecosystems are very complicated and it is rare that a predator will only have one prey item and a prey item will have only one predator. As a result, if a changed condition caused one prey species to decrease but another one to increase, the predator population may not be affected, and so on.
A localized group of organisms that belong to the same species is called a?
=)Population: when a localized group of organisms belong to the same species. (=
Is the sloth bear a predator or a prey species?
Sloth bears are prey to bengal tigers, but happens on occasion.
Is a species that has few individuals at greater risk of extinction than a species that has a large population size?
Yes , species with very small populations are at the verge of extinction as compared to large population .
What is the population size of predator species directly controlled by?
The population size of a predator species is directly controlled the availability (population size, etc.) of its prey species.
The population size of predador species is directly control les by?
Bottom-up regulation is defined as the size of predator and prey populations that is controlled by the scarcity of one or more resources.
What is the formula for Species population 2 predator?
dN2/dt=r2N2
Are all introduced species invasive?
No, not all introduced species are invasive because they may have a natural predator that will eat them in their new environment. Also because the species can be biologically controlled, chemically controlled or mechanically controlled.
Does one type of fishes population affect anothers?
It depends if one species of fish is a predator to another and the population of the predator fish is higher then the prey fish then the prey fish will be lower in population
How does a predator increase numbers of species in an ecosystem?
When a predator reduces the number of one species in a habitat, the population of competing species can increase. With less competition for food, water, and shelter, a species can thrive and reproduce more rapidly than when it is being out-competed.
How do crocodile fit in with environment?
Crocodiles are part of an ecosystem, and can be considered an apex predator. As a predator, they contribute to population control of prey species.
How can a new species with no predator affect other populations of species?
Their population could grow much faster, and they could compete with other species for food.
What type of growth curve is typically seen if no predator for a population of animals?
An exponential growth curve is typically seen if there is no predator for a population of animals or if the predator's population decreases. Without any, or many, predators to keep the species' population in check, the population may grow rapidly. An example is the Burmese python in Florida. Since it's an invasive species instead of native to the area, the Burmese python has no natural predators there and has experienced a surge in population.

What is limiting fators?
It is a controlled process, such as organization growth or species population or size, or distribution.
Relationship between a predator and prey?
A predator-prey relationship tends to keep the populations of both species in balance. As the prey population increases, so, after a slight lag, the predator population increases as well. As the number of predators increases, more prey are captured.
