For each of the species appearing in the food web, identify its domain, its kingdom and its role in the food web (producer, consumer 1st order, 2nd order, 3rd order, decomposer). You can do this under tabular form if desired. If certain trophic levels are missing from the diagram, identify them and specify their role. 2. Which population of food web organisms is associated with the highest level of available energy? Briefly explain your reasoning 3. Using a concrete example, make a link between this food web and the biogeochemical cycle of nitrogen 4. Briefly explain how the harbor seal (Phoca vitulina) contributes to the stability of this food web. Your answer must include at least three (3) different types of interactions, intra or interspecific. 5. What keeps the population size of gulls stable if this species has no predators
When species occupy the same niche, they must compete with each other for limited resources. Check each outcome that is likely to occur in the long-term if two species occupy the same niche. (Select all that apply): O Exclusion of one species from the entire niche, but not the other. OExclusion of both species from the entire niche. Persistence of both species throughout the entire niche. O Division of the niche into two smaller niches, each dominated by a single species. Alternating cycles where one of two species is initially excluded but subsequently becomes dominant, excluding the other.

1. On the savannah of African exist two animals, the African Wild Dogs (Lycaon pictus) and the Spotted Hyenas (Crocuta crocuta). Both of these animals occupy a very similar niche in their community – a social carnivore, which hunts in packs. However, when their niche does completely overlap the Hyena will win the fight. Use this information to answer the following questions. a) If these two animals were to occupy the same habitat, knowing what you know about these populations, what do you think the outcome of these two populations would be? b) The African Wild Dog hunts at twilight, while the Spotted Hyenas hunt at night. This separation of niches allows for what ecological process to happen? Why is it important that this process happens? c) The population of African Wild Dogs is much smaller, and very isolated from one another. If you were trying to prevent this animal from going extinct – what would you focus your resources on conservation wise? (There are a number of answers for…

Science Name: Date: Class: Range of Tolerance Data Analysis One of the responsibilities of an aquatic biologist is to make sure that the abiotic factors stay wiumh the acceptable ranges for the optimal help for the Species within the local ecosystem. Bcologists, including aquatic biologists, use the range of tolerance to monitor the number of different populations residing in the area. m order to do so they use statistical models. Create a graph displaying on the x-axis the ranges of abiotic conditions such as temperature to study the population of rainbow trout in the area ( use the launch model as an example), Label each interval with temperature range and condition. What Causing Stress in Rainbow Trout Population The optimal range is the amount of an abiotic factor that produces the highest possible population. For water temperature, this would be about 6-10°C. Label this area on the graph. 1. 2. The zone of physiologic stress occurs when an abiotic factor exists at levels that are…
