What would happen if the rabbit population suddenly doubled?
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. The grass population and hawk population would decrease.
How will harsh winters affect the rabbit population?
The effect of harsh winter on rabbit population would be that the population of rabbits decreases because of less availability of food. EXPLANATION: In harsh winters, the availability of food will be less because in winters plants usually do not have a good time.
In which season did the rabbit population increase the most?
spring season
Why does the rabbit population decrease in winter?
When the winter rolls around the now abundant rabbits are limited by food availability, and rabbit numbers decline until spring comes around again. Thus, rabbits will forage longer in places where they feel safe and forage for shorter periods in places where they do not.
How do limiting factors affect a population?
Limiting factors include a low food supply and lack of space. Limiting factors can lower birth rates, increase death rates, or lead to emigration. Limiting factors determine the carrying capacity of a population. Recall that when there are no limiting factors, the population grows exponentially.
What are 4 factors that reduce a population?
Mortality and emigration decrease the population. Thus, the size of any population is the result of the relationships among these rates. Natality, mortality, immigration, and emigration rates apply to every population, including the human population.
What are the 3 factors of population growth?
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 are the two types of population growth?
Exponential Growth Population growth can be described with two models, based on the size of the population and necessary resources. These two types of growth are known as exponential growth and logistic growth.
What are the 2 fundamental kinds of population growth curves?
Two modes of population growth. The Exponential curve (also known as a J-curve) occurs when there is no limit to population size. The Logistic curve (also known as an S-curve) shows the effect of a limiting factor (in this case the carrying capacity of the environment).
What are the three basic population growth curves?
The three basic growth curves are constant exponential, and logistic growth. Exponential growth can be found in nature when a current population multiply. Logistic growth is found in nature when the population grows.
What keeps a population size stable?
What keeps a population size stable? replacement fertility. This is the TFR that keeps population sizes stable.
What are the 2 fundamental kinds of population growth curves What are the causes and consequences of each?
Two types of population growth patterns may occur depending on specific environmental conditions: An exponential growth pattern (J curve) occurs in an ideal, unlimited environment. A logistic growth pattern (S curve) occurs when environmental pressures slow the rate of growth.
What qualifies as exponential growth?
Exponential growth is a process that increases quantity over time. It occurs when the instantaneous rate of change (that is, the derivative) of a quantity with respect to time is proportional to the quantity itself. The growth of a bacterial colony is often used to illustrate it.
How do you know if exponential growth?
If a is positive and b is greater than 1 , then it is exponential growth. If a is positive and b is less than 1 but greater than 0 , then it is exponential decay.
What is the difference between linear and exponential growth?
Linear growth is always at the same rate, whereas exponential growth increases in speed over time. This means that as x gets larger, the derivative also increases along with it – meaning that the graph gets steeper and the growth rate gets faster. In fact, the growth rate continues to increase forever.
How do you know if a function is growing or decaying?
When a > 0 and b > 1, the function is an exponential growth function. When a > 0 and 0 < b < 1, the function is an exponential decay function.
