How do predators-prey relationships help maintain a balance ecosystem?
Predators need to survive by eating the prey. When the predators
eat the prey, they control the population of the prey so that the
prey doesn't overpopulate.

How can the change in predators affect prey?
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.

Do predators and prey depend on each other If so how?
predators and prey do depend on each other in that the predators
rely on prey for food and they keep population of prey in check
which if they did not there would be over population and food for
prey would be decreased and they could die from lack of food.

Asked in Animal Life
Why is there fewer predators than prey?
There are always fewer predators than prey because there have to
be enough prey to reproduce and still keep the predators alive. If
there were more predators than prey, the prey population would
quickly be reduced to near zero and the predators would starve.

How can predators be said to control a preys population?
Predators eat prey; they usually hunt down and kill prey that
are weak, old, young, sickly or injured. This keeps the prey
population down and healthy and at the same time checks their
population in such a way that it prevents overpopulation. When prey
species are overpopulated, they tend to eat more plants than what
plant matter can support.

How does the populations of predators and their prey regulate one another?
When the population of the prey increases, the population of the
predators will also increase due to the large amount of food
avaliable. When the prey start to dissapear because of the large
amount of prey, the predators will also start to dissapear because
their food source is going away. When the predators die off, the
prey will take the advantage and start to reproduce and when the
predators start to see this, their population will then to get
larger.

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.

What is the connection of prey predator?
The connection between prey and predator is that predators are
organisms that eat other organisms, and prey are the organisms that
are eaten. For example, lion's are predators and zebra are an
example of their prey. This can also refer to plants: rabbits are
the predators and lettuce is the prey. Without prey, the predators
would have nothing to eat. Without predators, the preyy population
would increase to the point of overpopulation.

Asked in Animal Life
Why is it not a good idea to leave poisoned food for top level consumers in an ecosystem?
If the top level consumers, the apex predators, are poisoned and
their population decreases dramatically, then their prey animals
have no population control. The prey then has a population boom. In
turn, the prey animals decimate their food source, harmng the
ecosystem as a whole.

How does the population change affects the food chain?
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...

Asked in Animal Life
What happens to the prey population if the predator population increases?
The "prey population" would decrease. This is because the prey
are all being killed and don't reproduce enough to compensate: when
the prey population gets low the predator population will too
because they will have no prey to eat. When there are less
predators, the prey can reproduce and so on. This is a cycle.

Asked in Relationships
What is the relationships of predator vs prey?
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.

Predator and prey relationships?
In predator-prey relationships, the number of prey is always
MORE than the number of predators. The changes in the relationship
can be illustrated in the following ways;
1. Prey population increases
More food will be available for the predator.
2. Predator grows well and reaches reproduction age
3. Predator population increases
4. More predators preyed on the preys
5. Prey population decreases
6. Less food for the predators
7. Predators die of starvation and do not reach reproduction
age.
8. Prey population increases (goes back to one)

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....

How can changes in population size affect an ecosystem?
too many predators and the prey can die out and the predators
run out of food and die too, the plants they prey ate go out of
control, overpopulation of a species isn't a good thing, and only
we humans cause it. it doesn't naturally happen

How does predation help both predators and prey?
Predators benefit from predation because they get to EAT the
animal!! Doesn't everyone enjoy eating?
The prey benefit from predation because predators normally eat
the weaker and unhealthier members of the prey population.
Therefore, the stronger members of the prey population gets left to
reproduce and pass on their traits to their offspring.
"Offspring" is another word for "babies."

Explain how population sizes in nature are regulated?
The two primary factors that determine a population's size are
the availability of food, and the prevalence of predators.
In the abscence of predators, a population will grow until the
food it consumes becomes equal to the food that is provided by the
ambient ecosystem, available to the relevant
population through the food chain. After that, the
population cannot grow more unless the ecosytem suddenly is capable
of providing more food.
Predators regulate populations as a result of the connection
between predators and prey...
