6 The following question has two parts. First, answer Part A. Then, answer Part B. Part A: Which statement is a valid analysis about bison movement and the carrying capacity of Yellowstone National Park? A. The decrease in the northern herd's population is explained by its inability to migrate and the park's decreasing carrying capacity. B. The fact that bison only migrate in years of deep snow indicates that they have exceeded the park's carrying capacity. C. The carrying capacity for other animals found in Yellowstone has increased due to the bison's migration outside of the park. D. The movement of bison beyond park boundaries is not due to the bison population being too large for the park's carrying capacity. Part B: Which selection from the text provides evidence that directly supports this analysis? A. They move to lower elevation ranges during the winter months in response to snow accumulation and snowpack…
Part A: A population of 100 Asian elephants exhibits logistic growth. If the carrying capacity is 500 elephants and theper capita growth rate is 0.1 individuals/(individuals × year), what is the maximum population growth rate forthe population? part b: Based on the above question, what is the maximum population growth rate for the population if we assumedthe elephants were undergoing exponential growth?
89)You study a population of mussels recently introduced to a section of the Rideau River 8 years ago. You know that 13 mussels were originally let go in the river by a resident. These mussels have no predators. You know from your research that, under ideal conditions, the instantaneous rate of increase of this mussel species is 0.16. You also think the conditions on the river were ideal when the mussels were introduced. After surveying the food available in the river, you estimated that there is enough food to support a population of 11,200 mussels. How many mussels do expect to be in the river now?
Base your answer to the following question on the information and graph below and on your knowledge of biology. The graph contains information about an ecosystem. The graph below shows the carrying capacities of an ecosystem for three different species, 1, 2, and 3, that inhabit an area and the actual population sizes of these three different species in the area. Carrying Capacities of an Ecosystem Key O Carrying capacity O Actual population size 2 Species Identify which species population would have the least competition among its members. Support your answer using information from the graph. Number of Individuals in the Species
1. A population of black-capped chickadees grows continuously with a constant per capita growth rate. It took 2 years to grow from 400 individuals to the current population of 3000 individuals. How long will it take to grow from 3000 to 12,000? Write your answer in the box below. No credit will be given for your answers unless you show your work. Place your final answer in the box below. time to grow from 3000 to 12,000 =
Give typing answer with explanation and conclusion 1. Which of the following is most likely to increase the carrying capacity of an area for an organism? Choose ALL that apply A. Creating a migration corridor between patches of suitable habitat B. Harvesting the organism to reduce the population C. Eliminating a disease from the area D. Food source increases E. Climate change causing a mutualist to migrate out of the habitat
A biologist determines the growth rate of a population of 198 frogs in a marsh near Beaverhill Lake, Alberta, to evaluate the quality of the environment. The researcher finds that, in one year, 34 were born, 86 died, 12 migrated into the marsh, and there was no emigration. a. frogs are considered an indicator species for the quality of the environment. Determine whether the growth rate of this population in one year is a cause for concern. if so, what might the concerns be?
1. Moose Management Area 6, WMU 350 In 1993–94, aerial counts of moose populations in Wildlife Management Unit 350 showed a density of 0.45 moose/km2 in the 5788 km2 area surveyed. What was the total population size (N)? 2. Another population count of Moose Management Area 6, WMU 350 occurred in 1997–98.This time, the population size was estimated at 3204 moose. What was the population density (Dp)? 3.Compare the two population sizes from the two counts of WMU 350 and determine the following variables. Show your work. ΔN: Growth rate: Per capita growth rate:
In 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals. Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus the forest management personnel feared that overgrazing might lead to mass starvation. Since the area was too remote for hunters, the wildlife service decided to bring in natural predators to control the deer population. It was hoped that natural predation would keep the deer population from becoming too large and also increase the deer quality (or health), as predators often eliminate the weaker members of the herd. In 1971, ten wolves were flown into the island. The data collected during this program are shown in the following table. The Population Change is the number of deer born minus the number of deer that died during that year. Fill in the last column for each year. The first has been calculated for you. Then graph the deer and wolf populations on the graph below.…

Lake Winnipeg is a shallow lake composed of two basins: a wide north basin and a narrow southbasin that provides a habitat for over 50 different species of fish. Each of the statements belowinvolves a situation that will affect the growth of a population. Classify each of the statements asDD (density dependent) or DI (density independent) and give a reason for your choice.1. Rainbow smelt and yellow perch attempt to occupy the same area. The more aggressive smeltsurvive; the perch do not. __________________________________________________2. A severe flood brings a lot of sediment and silt into Lake Winnipeg. The turbidity of the lakeincreases greatly. ________________________________________________________3. Since northern pike prey on yellow perch, an increase in the perch population causes anincrease in the pike population. _______________________________________________4. Many fish die due to an increase in water…
