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.
It depends. For instance, a stoat can kill a much larger rabbit. A lioness can bring down and kill a larger zebra.
predators eat all the prey....
Normally.
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.
Humans affect the lynx population by invading their habitats with construction and the removal of trees. Lynx are hunters and their prey is limited due to humans hunting for sport and removing living space for both predator and prey.
They keep the population of the prey down, which in turn keeps the population of the predator down. This helps them both not become extinct.
it stays the same or increases with the preythe prey will run out of food making it's population decrease. that will cause the predator's population to go down because of the lack of food
A prey is what a predator hunts down to kill and eat. A prey's predator is what eats it. For example: A gazelle is the prey of a leopard (predator).
A prey
Predator-prey relationships can regulate population sizes by keeping prey populations from growing unchecked. Predators hunt and feed on prey, reducing their numbers. As prey populations decrease, predator numbers may also decline due to reduced food availability, which in turn can allow prey populations to recover. This cycle helps maintain a balance between predator and prey populations.
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
the predator-prey cycle is the increase and decrease in population size of the predator and its prey
Well, If there is no predator, then the prey's population will be too high and it will eat all of the food it has. Also if there is no prey, then there will be no predator.
a predator affects its prey how it trys to attack it and eat.
Oftentimes, the predator holds the population of a particular prey in check. Without predators, the population of the prey will flourish. If the change of predators you refer to means 'type of predator', the prey will adapt -or vanish.
The prey could easily be poisonous and kill the predator, cutting down population. Or the prey is over populated and the predator has more food causing them to be able to produce more population!
True. A decrease in prey population can lead to a decrease in the predator population due to reduced food availability. The predator population relies on the prey as a food source, so a decline in prey numbers can impact the predator population size.
It is true to say that; If a prey population decreases, the population of its predator probably will decrease as well.
The peak population of a predator lags behind the peak population of the prey because the number of predators will not increase until after the food supply increases. This means that the prey must increase first and then the predator population can grow.
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.
