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
True or false if a prey population decreases the population of its predator probably will decrease as well-?
It is true to say that; If a prey population decreases, the population of its predator probably will decrease as well.
An increase in predator population will directly result in?
A decrease in the prey population
An increase in a predator 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 population will directly result in .?
A decrease in the prey population
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!)
Why is there lag time between the increase in the prey population and the predator population?
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 happens to the predator population when the prey populations decreases?
The predator population may also decrease due to a decrease in available food source, leading to increased competition among predators. This could result in some predators migrating to find new prey or population decline due to lack of resources. Ultimately, the predator population may be negatively impacted by a decrease in the prey population.
Why are predator-prey relationships important in an ecosystem?
Yes. The predator, of course, needs food, but the prey benefits too because if the predator did not eat the prey, the prey population would grow and grow until food ran and and the prey population would die of starvation.
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.
What are predator and prey relationships?
This is a much studied relationship that one might learn about in grade 10 science or Biology 11. Predators rely on the population of their prey for sustenance. An increase in predators could lead to a decrease in the population of the prey which in turn leads to a decrease in the predator population. As the predator population decreases the prey population can again increase and the cycle begins anew.
