Introduction:
The carrying capacity can be defined as the maximum number of organisms that can be supported by the resources present in a certain environment. All the physical factors such as temperature, food availability, presence of gases in the environment and the amount of waste determine the carrying capacity.

How do humans differ from other species in the ability to “choose”a carrying capacity for their environment?
If the rate of some process is governed by the abundance of prey individuals, we say that it is prey-dependent. Give some examples of prey-dependent processes.
Interpret the following graphs:
In the graphs, the number of days are 18.. 1 day is equal to 60 sec. For the first graph, days are taken on x-axis. The mean foraging times are taken on y-axis. For the 2nd graph, percentage of prey caught during first half of winter(1-6days) were taken on x-axis and percentage of prey caught during 2nd half of winter(7-12days) were taken on y-axis.

- Consider a trophiccascade with 4 levels: 1) predatory fish that consume planktivorous fish, 2) planktivorous fish that consume zooplankton,3) herbivorous zoplankton that consume phytoplankton, and 4) phytoplankton. True or False: A reduction in predatory fish will increase the level of phytoplankton. True Falsearrow_forwardLook at figure 1 in the passage. Which of the following relationships is BEST shown by the data? The more massive the penguin, the more food is delivered to the offspring. B. The maximum efficiency in food foraging is reached at about 20 % sea ice concentration. The amount of food delivered is about the same at 12% and 15% sea ice concentration. The greater the sea ice concentration, the greater the efficiency in delivering food. V07:16arrow_forwardDecribe Brown’s large granivore experiment and what was his hypothesis (Chapter 13)? Why did Brown’s research team create controls by completely fencing study plots and then cutting holes in their sides to allow free passage of rodents into and out of the plot? Why not just compare the density of small rodents in the large granivore removal plots with their densities in the surrounding desert? Why did they look at insectivores and what did the lack of response in insectivores indicate? Why did they repeat their large granivore experiment?arrow_forward
- A niche is loosely defined as an organism's role in its environment, which can include factors such as feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Keeping Gause's law in mind, do some research on the California red-legged frog and the North Pacific tree frog (use wiki or another Google search). Create a chart comparing the two with respect to their niche or lifestyle that can explain how these two frogs can co-exist in the same ecosystem.arrow_forwardDippers (Cinclus cinclus) are small birds that can be found along fast-flowing streams in Europe and Asia. They feed on insect larvae, especially those of caddis flies (Trichoptera), which they catch by sticking their heads under water and turning over stones. Describe the relationship between the abundance of caddis fly larvae and dippers?Why, is caddis fly larva abundance expressed as ‘relative abundance’? using the data in Table 2arrow_forwardPlease do by handarrow_forward
- The relationship between predator and prey populations has been studied by computer simulation using equations which form part of a mathematical model devised by Lotka and Volterra. The data in Table 6.10 show the results of such a simulation when the prey population begins with 20 individuals and the predator population begins with six individuals. 1.Explain why the peaks in the predator population occur after those in the prey population. 2. This simulation assumes one prey species and one predator species in an imaginary ecosystem and is based on mathematical equations. Why is it likely to be too simplistic to describe accurately what happens in nature?arrow_forwardHow does increased atmospheric CO2 affect the ability of marine invertebrates to grow hard structures, such as the shells of mollusks or the skeleton of stony corrals? When exposed to high CO2, marine organisms no longer need hard shells and facultatively reduce their shells through phenotypic plasticity. CO2 reacts with water to produce lye. As a result, increased atmospheric CO2 causes an increased pH in the water preventing these animals from producing hard structures. CO2 reacts with water to produce carbonic acid. As a result, increased atmospheric CO2 causes a reduced pH in the water preventing these animals from producing hard structures. CO2 and other greenhouse gases cause increased heat energy to be maintained within the ocean. This increase in heat energy prevents shell formation in many marine animals. When exposed to high CO2, marine organisms no longer need hard shells and evolve through natural selection to grow reduced shells.arrow_forwardThe figure below illustrates the thermal performance curve for the intrinsic rate of increase (r) of an Aphid insect. Imagine you are studying a population that was historically exposed to 25C during the breeding season, yet climate-change predictions suggest that the population will be exposed to an average of 32C by the end of the 21st century. Select the changes below that you predict could at least partially mediate the consequences of climate change for population growth. Hint: First think about how the climate change described will and will not challenge homeostasis. Next, recall some of our earlier modules that talked about how animals can alter behavior, physiology, etc to maintain homeostasis. Select the answers that could allow the animals to maintain homeostasis given the scenario. a) Do nothing (i.e. no changes) b) Evolve a larger body size with smaller surface-area to volume ratio c) Disperse to lower elevation habitats d) Disperse to higher elevation habitats…arrow_forward
