What would happen if the rabbit population increased?
Explanation: 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. This means less food for the foxes and hawks.
What happens with the rabbits when the wolf population increase?
2. What happens to the bunny population when the wolf population increases? The bunny population slows its rate of increase and then decreases as the wolf population increases.
Why has the rabbit population increase?
This prolific species usually has three or four litters per year, with four to six young per litter. Every 10 years, more or less, the rabbit population reaches a peak that is eventually brought down by disease and strife. For predators, rabbits are the original fast food.
What affects rabbit population?
Rabbit populations are restricted by traits like food availability and predation. A female cottontail rabbit (Sylvilagus floridanus) can give birth as often as seven times a year. In nature, the size of a population and the rate of population growth are influenced by what ecologists call “limiting factors.”
How do you think a period of harsh winters will affect the rabbit population?
Predict: Rabbits reproduce in the spring. How do you think a period of cold springs will affectthe rabbit population? A period of cold springs will reduce the rabbit population because the rabbits will not be as active, and the food supply will be reduced.
What affects population size?
Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.
What are the 3 factors of population change?
Three primary factors account for population change, or how much a population is increasing or decreasing. These factors are birth rate, death rate, and migration.
What is the impact of overpopulation?
2 Population is growing rapidly, far outpacing the ability of our planet to support it, given current practices. Overpopulation is associated with negative environmental and economic outcomes ranging from the impacts of over-farming, deforestation, and water pollution to eutrophication and global warming.
What are the causes and effects of overpopulation?
Poverty is believed to be the leading cause of overpopulation. A lack of educational resources, coupled with high death rates leading to higher birth rates, result in impoverished areas seeing large booms in population.
What are the impacts of population growth on resources?
The increasing population numbers and growing affluence have already resulted in rapid growth of energy production and consumption in India. The environmental effects like ground water and surface water contamination; air pollution and global warming are of growing concern owing to increasing consumption levels.
What are the negative effects of population growth?
In addition, the population growth also leads to negative impacts on the environment such as increasing waste water, household waste, and other industrial wastes due to human has increased their activities of industrial production.
What are the social impacts of growing population?
Social Infrastructure: Rapidly growing population necessitates large investments in social infrastructure and diverts resources from directly productive assets. Due to the scarcity of resources, it is not possible to provide educational, health, medical, transport and housing facilities to the entire population.
What are the impacts of population growth on the environment?
One of the largest environmental effects of human population growth is the problem of global warming. Some scientists fear that global warming will lead to rising sea levels and extreme weather conditions in the future. In order to support the growing population, forests are being destroyed at an alarming rate.
What is the impact of population growth on energy?
The growth of world population in this period was responsible for 52% of the energy growth, while growth in per capita energy use was responsible for 48% (excluding causal connections between population and energy use per capita).
What effects of population growth on harnessing of energy are observed?
Answer. The global population is increasing every year in a devastating high rate. That’s why the dependency upon the various energy sources had also increased in a high rate. And for the same reason a high amount of energy is harnessed from the different available energy sources in our planet.
How does population growth affect employment?
Overpopulation causes more competition for employment. Not only does increased competition for work make it tougher to find a job, employers can hire employees for a lower wage because there are more applicants than jobs to go around.
Does climate change affect population growth?
Per-capita greenhouse gas emissions may drop, but the population bulge will continue to contribute to a dangerous increase in greenhouse gases in the atmosphere. Time is short, but it not too late to stop runaway global warming.
What are the negative effects of climate change?
More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities. As climate change worsens, dangerous weather events are becoming more frequent or severe.
