Population Growth by Ashton
A scientist was studying a population of elephants. The first year, he counted a population of 80. Over the next eight years, the population's numbers were 94, 100, 103, 110, 125, 120, 125, 120. The population never exceeded 125. What is the carrying capacity for this population?
125
Based on this population growth graph, what can be determined about the population? mc022-1.jpg
The carry capacity is around 0.4 million
What would most likely happen to the chipmunk population in 2014 if the population went up to 22 million in 2013? mc026-1.jpg
The chipmunk population would crash.
The overall population of a species has increased. What could have occurred to allow this to happen?
The immigration of the population is greater than the emigration.
In a year, a population of lions had four births, two deaths from disease, one natural death, five emigrations, and five immigrations. In the same year, a population of zebras had five births, three deaths, four emigrations, and one immigration. Which best explains the data?
The zebras have a lower population growth than the lions have.
Which type of population growth is shown in this graph? mc014-1.jpg
logistic
Which is the change in size of a group of organisms of the same species over time?
population growth
A population of sixteen emu grew to thirty-nine in one year. After two years, the population had grown to forty-eight. The maximum number of emu that the environment can support is approximately sixty due to limited resources such as food and water. The carrying capacity of the emu population is
sixty
