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.
What else can I help you with?
The population size of a predator species is directly controlled by?
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 do pedatores help 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.
How are the terms predator and prey related?
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).
What happens to the prey population if the predator population increases?
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
What happened to the numbers of lynx as the hare population increased?
As the hare population increased, the number of lynx would also increase due to the higher availability of prey. This increase in lynx population would eventually lead to a decrease in the hare population as the lynx preyed on them, creating a cyclical pattern of predator-prey dynamics.
The size of the population can affect the size of a predator population?
A prey
Describe how predator-prey relationship can be a mechanism of population control?
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.
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
What happens to the predator population when the prey population is above the predator isocline?
When the prey population is above the predator isocline, the predator population tends to increase as they have more food available to hunt and consume. This can lead to a rise in the predator population until it reaches a balance with the prey population.
What is meant by 'predator prey cycle'?
the predator-prey cycle is the increase and decrease in population size of the predator and its prey
How does a predator affect its prey?
a predator affects its prey how it trys to attack it and eat.
How do a predator and its prey control each other’s population?
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.
How can the change in prey affect the predators?
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.
What relationship do predator-prey isoclines illustrate in ecological systems?
Predator-prey isoclines illustrate the relationship between predator and prey populations in ecological systems. They show the equilibrium points where the populations of predators and prey stabilize, indicating how changes in one population affect the other.
How can prey control a predator's population?
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!
How can a prey control a predator's population?
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 or false If a prey population decreases the population of its predator probably will decrease as well?
True, if the number of prey decreases, the predators will have nothing left to eat and will slowly starve. In some cases the predators will become cannibalistic (eat its own species) to prevent it self from starving to death.So the answer is true, if a prey population decreases the population of its prey will decrease as well.
