A population of 1,492 finches is introduced to a rainforest. Over the next year, the finches show a death rate of 0.395 while the population drops to 1,134. What's the birth rate for this population? Is this proving to be a suitable habitat? (Two answers)
a) Yes, this is a suitable habitat. The birth rate is higher than the death rate.
b) No, this is not a suitable habitat. The birth rate is much lower than the death rate.
c) 589
d) -358
e) 0.155
f) 0.845
Which of the following is true of a population approaching its carrying capacity?
a) The population’s emigration is greater than its immigration.
b) The population has access to unlimited resources.
c) Intraspecific competition decreases.
d) The population’s rate of increase approaches zero.
The global human population has surpassed 7 billion, far exceeding our population’s size throughout our history on Earth. Name some specific means by which we have apparently raised Earth’s carrying capacity for our species. Do you think we can continue to raise our carrying capacity? How might we do so? What limiting factors exist for the human population today? Might Earth’s future carrying capacity for us decrease? Why or why not?

- Two alien species compete for resources on a planet far far away. Their initial populations are 100 and 1000 and their specific growth rate is 0.02263/year and 0.02/year and their yield coefficient is 0.95 and 0.85 respectively. When the first species begins to consume more than 50% of the resources the other population will be inevitably be annihilated. How many years does it take for this to occur? Answer:arrow_forwardDuring what phase of the growth curves in each diagram is the population just beginning to colonize an area? (C) a) Which type of population growth appears to continue unchecked? b) The growth curves in the Model are often referred to using the letters of the alphabet they resemble. The logistic growth curve is sometimes referred to as an S-curve. What letter would you use to describe the exponential growth curve? c) What causes the population to slow down during logistic growth? d) The maximum population an environment can sustain is affected by environmental factors that cause the population to level out or become stable. What term is used to describe this level of logistic growth? Diagram A-Exponential Growth Curve Population Numbers Exponential growth Lag phase Time Population Numbers Diagram B-Logistic Growth Curve Lag phase Time Carrying capacity (K) Pressure begins due to environmental resistancearrow_forwardAre the following statements True or false? 1) Population growth of many species is expected to be either exponential or geometric, unless some factor such as competition or predation is introduced. 2) The age distribution of populations reflects the influence of per capita rates of births, death, immigration, and emigration.arrow_forward
- 1.) At approximately what year did the human population enter an exponential growth phase? 2.) Prior to that time, what was the approximate carrying capacity of Earth? 3.) State three significant technological developments that have acted to increase the carrying capacity of Earth’s environment since that time. 4.) Provide two examples of density-dependent factors that are contributing to or have the potential to contribute to environmental resistance in human populations.arrow_forwardWhich of the following populations would be growing? a) Geometric rate (1) = 0.63 b) Exponential growth rate (r) = 0.63 c) Net reproductive rate (R0) = 0.63 d) All of the above populations are growingarrow_forwardPronghorns look very similar to antelopes and are considered the fastest mammal in North America. They can be found in the Southeastern parts of Alberta. In the 1800s, it is thought that the population of pronghorns reach 35 million in the Prairies. By 1924, only 20,000 pronghorns could be found in Alberta. In 1996, only 9,600 remained. What is the per capita growth rate of pronghorns in Alberta between 1924 and 1996? Express your answer as a value between 0 and 1 rounded to two decimal places. If the population is decreasing indicate this with a negative sign. Answerarrow_forward
- Back at the original iguana population, only 40 iguanas remained. This population also has a growth rate of 0.6 and generation time of 2 years. But the island on which this population resides is much smaller and has a carrying capacity of 200. How many iguanas do you expect to find in the original population after 6 years?arrow_forwardWhich curve on the graph represents a species that produces high numbers of offspring with little paternal care? a) Graph 1 b) Graph 2 c) Graph 3 d) Graph 4arrow_forward8)Which of the following questions would be considered ecological questions? choose all that apply a)How does the availability of rainfall affect pollen production in mulberry trees? b)How do the population dynamics of hawks affect the population dynamics of lizards? c)How does elevation affect the amount of rainfall? d)How did the mouse species present in the Mojave Desert arise? e)How does a mutation in a gene for amylase affect nutrient absorption in white-tailed deer? f)None of these are ecological questionsarrow_forward

What factors influence the survival rate of a deer population? How does the introduction of a new predator affect the species in an ecosystem? How does sunlight affect the photosynthesis rate of a single tree? How does food availability affect the growth rate of a mouse population?arrow_forwardAssume that for a given population of moose, the per-capita birth rate remains constant with population size. However, as the moose population size increases there is a linear increase in the probability of starvation and subsequent mortality due to intraspecific competition. a) On a single graph, draw the relationship between moose density and the per capita birth and death rates for this population. b) Assume that the population does not experience competition from other species, nor predation. Write out the equation that would best be used to describe the change in population growth from one time interval to another.arrow_forward
