There would be more food for the rabbits and slugs, so their populations would increase. However,
there would be less food for the frogs and voles
, so their populations would decrease. … because If enough rabbits migrate, there would be insufficient food for the hawk population, leading to a decrease in hawk numbers.
What would happen if the rabbit population continued to decrease?
There would be more food for the rabbits and slugs, so their populations would increase. However,
there would be less food for the frogs and voles
, so their populations would decrease. … because If enough rabbits migrate, there would be insufficient food for the hawk population, leading to a decrease in hawk numbers.
What could possibly happen if there is a decrease in number of rabbits?
The consequent decline in the Rabbit population caused
dramatic changes in agriculture and the native fauna and flora
. It promoted woodland regeneration and increased grassland and cereal production; herb and grass height increased, flowering was noticeable and plant successions ensued.
Which factor may increase a rabbit population?
Any of these factors—
food, shelter, breeding sites, predators, and more
—may serve to limit the growth of a rabbit or toad population. Often, the population is affected by several limiting factors that act together.
What do you think would happen to the population of rabbits if the population of foxes decreased?
If foxes decreased, the rabbit population would
increase
because there wouldn’t be as many foxes to eat them.
Why has the rabbit population increase?
Many factors are involved in this cycle, such as weather, habitat conditions, predation, and disease.
About every ten years
, cottontail rabbit numbers will increase dramatically, causing a population “explosion.”
How can we reduce rabbit population?
Integrated control
Long-term control involves an initial effort to reduce rabbit numbers then destroying warrens and removing harbour (e.g. fallen logs, blackberry bushes) to prevent re-establishment in the same location. Excluding rabbits from potential food sources can also help to manage impacts.
What will happen if there is a sudden increase in the number of animals?
If one animal’s population increases,
the population of animals that eat that animal might also increase
. … Other changes in limiting factors can cause a population to decrease. If a population becomes diseased, the population may decrease and the population of animals that eat the diseased animals will also decrease.
What would happen to this food chain if we doubled the population of the rabbits?
In the stable food chain shown, what would you expect to happen initially if you were to suddenly double the population of rabbits?
The populations of the other three species would also increase
. The populations of the other three species would decrease.
What factors affect the population size?
Population growth is based on four fundamental factors:
birth rate, death rate, immigration, and emigration
.
What factors can stop a population no matter how many organisms are living in a certain area?
A limiting factor
is anything that constrains a population’s size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources.
What can limit human population growth?
Limiting Factors to Population Growth. For a population to be healthy, factors such as
food, nutrients, water and space
, must be available. … Limiting factors include a low food supply and lack of space. Limiting factors can lower birth rates, increase death rates, or lead to emigration.
Do owls eat rabbits?
Owls are opportunistic predators, which means that they will hunt and eat anything available to them, whether small rodents or larger mammals. …
Almost all species of owls can and will hunt rabbits
because they are a good food source.
What would happen to the population of grass if the rabbit population increases?
When the population of rabbits will increase there
will be a decrease in population of grass plants
, as more and more rabbits will eat grasses so there will be a decline in grass plants.
What happens with the Wolves when the rabbit population decrease?
What happens to the wolf population when the bunny population decreases?
The wolf population slows its rate of increase and then decreases
. the wolves, and an absolute maximum of 1/3 of the current wolves have a chance of surviving, thereby reducing their numbers drastically in the next round.
What happens if the food chain is disrupted?
Due to disruptions in the food chain,
many predator animals will be forced to leave their natural habitats since they do no longer find sufficient prey animals to ensure their food supply
. … Depending on the severity of the decrease in prey animals, these predators may even become endangered or even extinct.
