- The pelagic zone of the ocean is the area of the ocean that is neither close to the bottom nor close to land. There are a wide variety of organisms that inhabit the pelagic zone. Phytoplankton float along the surface, using photosynthesis to produce food. Zooplankton are tiny organisms that float in the surface waters and feed on the abundant phytoplankton. Krill, small crustaceans, also feed on phytoplankton. They display vertical migration in which they swim at deeper depths during the day and then come up to the surface waters at night to eat. What is the relationship between zooplankton and krill? a) Symbiosis b) Competition c) Parasitism d) Commensalism e) MutualismScience 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…a which is the simplest unit of life, is surrounded by a membrane and contains macromolecules.
- You find an unknown species in a fishing net and are not sure where it came from. To keep it in the lab to learn more about it, and find out where it came from, what would be the best approach? Set up an estuary tank because the intermediate salinity is most likely to support life. Carefully monitor temperature, salinity, and oxygen levels to detect quickly if they are not correct. Use freshwater and lab temperatures because a freshwater environment is less stressful than a marine environment. Set up a standard marine tank because salinity and oxygen levels are similar in all marine environments. Set up an environment with low oxygen levels and low light levels to lower stress.Describe the conditions or circumstances when organic material (i.e. living things) would not be preserved. There are 2 ideas for where life started. Describe both of them in terms of why or why not they are feasible.A factory located near a river pumps heated water into the river. The heated water decreases the amount of oxygen in the river. An STS class is discussing what this decrease in oxygen would do to the river. Bam thinks less oxygen would change the type of organisms that live in the river. Mel thinks the type of organisms would stay the same, but there would be a lot less organisms. QUESTIONS: Who do you agree with? Bam?Mel? both Bam and Mel? Why are they right? What would happen if oxygen in a stream decreases?
