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 happens to country with little population?
Countries with small populations may face challenges such as limited workforce, reduced tax base, and difficulties in providing a wide range of services. However, they may also benefit from closer-knit communities, lower crime rates, and a sense of tight-knit national identity. Small populations can also struggle to compete economically and politically on the global stage.
What happens to the density of a population due to mortality and emigration?
Well for example, in the USA, for when one person dies 4 are born and statistically at least 4 migrant families a day come in! So the population becomes more dense, as for England when one dies 2 are born and with an average of 1.75 migrants entering the UK on a dailybasis.
What is census and when does it happen?
A census is a count of a population in a specific region at a particular time. It typically happens every 10 years in many countries to gather information on the demographic, social, and economic characteristics of the population.
What happens when the death rate is higher than the birthrate?
When the death rate is higher than the birthrate, the population begins to decline. This can lead to an aging population, reduced workforce, and potential strain on social services and healthcare systems. It may also impact economic growth and development in the long term.
What happens to predator population when the prey population is eliminated?
The predator population also goes down because there is less for it to eat. This is called the food chain.
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 happens to the populations after an eruption?
The population decreases as they will be afraid that another eruption may ocur. The population may also decrease because of the ammout of deaths caused.
What happens as the population decreases?
As a population decreases the death rate is higher or equal to the birthrate.
What happens to the number of prey as the number of predator decreases?
The numbers of prey will normally increase.
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 happens when there is a decrease in sunlight over the algal population?
The population decreases.
Does the process of evolution occur at the individual level, where selection happens to individuals, or at the population level, where selection happens to populations?
Evolution occurs at the population level, where selection happens to populations rather than individuals.
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
What happens to population when the death rate decreases?
Birthrate Usually Increases.
What happens when a populations birth rate exceeds its death rate?
population goes up.
What happens when you kill of most of the hawks?
The hawk population increases and the other populations decrease.
