Why is there lag time between the increase in the prey population and the predator population?
Wiki User
∙ 6y ago
Because when a predator feeds on prey, the prey population goes down. When the prey population goes down, then so does the predator population. When the prey population recovers, then the predators soon after prey on the prey, and it repeats.

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.
What does the size of the host population control?
the parasite population
Which of the following is most likely to cause increases in a predator population?
An increase in the prey population is most likely to cause increases in a predator population due to an abundant food supply. This can lead to more successful breeding and survival rates for predators.
What is one of the best known mechanisms of population control is the relationship?
the best known mechanism of population control is the predator-prey relationship
How does the population of prey affect the population of the predator?
Predator and prey evolve together. The prey is part of the predator's environment, and the predator dies if it does not get food, so it evolves whatever is necessary in order to eat the prey: speed, stealth, camouflage (to hide while approaching the prey), a good sense of smell, sight, or hearing (to find the prey), immunity to the prey's poison, poison (to kill the prey) the right kind of mouth parts or digestive system, etc. Likewise, the predator is part of the prey's environment, and the prey dies if it is eaten by the predator, so it evolves whatever is necessary to avoid being eaten: speed, camouflage (to hide from the predator), a good sense of smell, sight, or hearing (to detect the predator), thorns, poison (to spray when approached or bitten), etc. The fastest lions are able to catch food and eat, so they survive and reproduce, and gradually, faster lions make up more and more of the population. The fastest zebras are able to escape the lions, so they survive and reproduce, and gradually, faster zebras make up more and more of the population. An important thing to realize is that as both organisms become faster to adapt to their environments, their relationship remains the same: because they are both getting faster, neither gets faster in relation to the other. This is true in all predator-prey relationships.
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
Why does the peak population of a predator lag behind the peak population of the prey?
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.
An increase in predator population will directly result in?
A decrease in the prey population
What happens when the cycling of matter in ecosystems is disrupted?
The predator eats the prey in the food chain. As the population is stable, the food chain won't wreck. There's an interdependence between the prey and the predator in the food chain. The prey should be there to feed some food to their predator, and the predator also needs to be there to control their prey population from exploding. Changes in animal population can wreck the food chain. If the prey population decreases, the predator population would also decrease as there'll be less food for them to eat. If the predator population decreases, the prey population would increase because less predators means less preys gets hunted down, so there'll be more preys. If the prey population increases, then the predator population would also increase because there'll be more food for them to eat and there should be more predators to take more control patrol of their prey population. If the predator population increases, then the prey population would decrease because more predators means more preys gets hunted down, so there'll be less preys. Animal Population Change Formula: Prey Decrease→Predator Decrease Predator Decrease→Prey Increase Prey Increase→Predator Increase Predator Increase→Prey Decrease
An increase in a predator will directly result in?
A decrease in the prey population
An increase in a predator population will directly result in .?
A decrease in the prey population
What are some ecological example of a refuge?
(1) In a well-mixed population, the predator quickly finds prey, the prey disappear, and the predator soon follows. (2) By increasing the space between population subunits, the interaction between the predator and prey is prolonged. (3) By slowing the movement of the predator, the interaction between the predator and prey is prolonged. (4) By adding habitat patches that don't support prey, the interaction between the predator and prey is prolonged. (5) By adding barriers to predator dispersal, the interaction between predator and prey is prolonged.
How does a change in the prey population effect the predator population?
A change in the prey population effects the predator population because if there are alot of preys, then the predators would eat the preys and the population of predators would increase. But on the other hand, if there are not enough preys, the predators would starve and die which would decrease the population of predators.
How would this impact two populations?
Gene flow would increase between the two halves, and speciation would not occur
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.
What is meant by 'predator-prey cycle'?
When the predator eats its prey, the prey population will go down because they're being eaten. Now there's is not enough prey because it has been eaten, there's nothing for the predator to eat. So, some die from startvation. Then the prey population increases because they are not being eaten, since the predators died of starvation. - Alexis (future vet!)
What relationship occurs between prey and another organism?
predator kills and eats prey for its survival. When the predator population increases, the prey population decreases because of too many hunters. When the prey population decreases, the predator population decreases because of the lack of food. Then, the prey population increases because there aren't that many predators and the process repeats itself.
