Question
Chapter 31.3, Problem 1CSC
Summary Introduction
To determine: The way by which minimum viable population of wolves influences the sustainability of other animals in the food web.
Introduction: The linear network of links present in a food web beginning from the autotrophic producers and ending with the apex that includes predator species is called a food chain. The various positions occupied by organisms in a food chain are called the trophic level.

Which of the following might you expect if you increase the amount of energy (and nutrients) into an ecosystem?
Group of answer choices

increase the consumption of fossil fuels
increase the number of trophic levels
decrease the standing crop
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.
A small lake is capable of supporting both bluegill and smallmouth bass. These two bony fish species compete for similar food resources. The carrying capacity of this lake for bluegill (K,) is 1,500 and for bass (Kz) is 500. After some careful measurement, we find that a is 0.5 and that ß is 0.25. We stock the lake with 250 bluegill and 750 bass. Over time, will both species be able to co-exist? If not, which one will be driven to extinction in this lake? If so, approximately how many of each species will be present? Please show math on paper and Draw Graph on paper! Please

- Shrimp fishing off the coast of Georgia was closed in 2001, due to a drastic reduction in the shrimp population. Landings of blue crab plummeted in 2002 and 2003, as five years of drought and greatly reduced freshwater flow from underground aquifers led to increased salinity in coastal estuaries. These habitats between open ocean and fresh water are the “nurseries’ for many marine animals. Using information you learned in this lab, speculate about possible causes for the decline in shrimp and blue crab populations.arrow_forwardDRAW IT In the Chesapeake Bay estuary, the blue crab is anomnivore that eats eelgrass and other primary producers as wellas clams. It is also a cannibal. In turn, the crabs are eaten byhumans and by the endangered Kemp’s Ridley sea turtle. Basedon this information, draw a food web that includes the bluecrab. Assuming that the top-down model holds for this system,describe what would happen to the abundance of eelgrass ifhumans stopped eating blue crabs.arrow_forwardIn some marine habitats in New England, the population density of lobsters has been depleted due to heavy fishing. When this happens, it often follows that the diversity of species in the biological communities is reduced. Based on this observation, how would you characterize lobsters? a keystone organism a decomposer a crustacean a superior predator a producer The composition of a community refers to the nutrients available in the soil. type of succession that occurs locally. sunlight available to drive the energy needed for metabolism. extent vegetation covers the ground--a desert has low composition. types of species adapted to living there. Small fish sometimes swim very close to large predatory fishes such as sharks. There is no risk since the shark does not feed on these smaller fish. The small fish are able to eat the remains of prey such as seals that the shark rips apart when eating.…arrow_forward
- Two islands exist in the eastern Pacific. The animal and plant life on both islands were wiped out by a freak storm at the same time. Island "A" is 100 miles off the coast of Peru; whereas island "B" is only 10 miles off Peru's coast. Island "A" is much smaller than island "B" (20 square miles as opposed to 75 square miles). Which island has a higher species richness equilibrium ? Explain why using the Theory of Island Biogeography.arrow_forwardWhat does the fishing-down-the-food-web hypothesis predict? The lowest landings have the lowest trophic levels The lowest landings have the highest trophic levels None of the options are correct The highest landings have the lowest trophic levels The highest landings have the highest trophic levels In the movie regarding lactose intolerance researchers examine what type of artifacts to determine if milk was in the diets of ancient settlements across Europe and Africa? None of the options are correct Shovels with cow feces DNA Paintings on cave walls Glass cups with milk residue Pottery pots and animal milk fatsarrow_forwardIn a food web, the numbers of each organism typically exist in a relatively stable proportion. If an oilspill killed a large amount of zooplankton, what would be the next thing that would happen?A The number of tiger sharks would decrease.B The number of phytoplankton would increase.C The number of clams, mackerels, and jellyfish would decrease.D The number of herring, whelk, squids, and loggerhead turtles would increase.arrow_forward

You may discuss specific species of organisms, or can discuss organisms that occupy a specific trophic level in an ecosystem’s food web. Explain why you would select these species or this trophic level.arrow_forward
- A private reptile breeding facility near the Everglades was destroyed by Hurricane Andrew in 1992. This event contributed to the original influx quantities of pythons in the wild. Pet owners also contributed to the introduction of these reptiles to the Everglades by releasing pets that had grown too large to care for. These reptiles are considered species to this ecosystem. can someone please write an explanation that describes the impact of the Burmese python on the Everglades? Claim: Evidence: Reasoning:arrow_forwardo determine the role of a native starfish species in a coastal ecosystem, zoologist Robert Paine removed starfish from some intertidal pools and not others. He then observed how the community changed in response to the loss of starfish by comparing the diversity of the community in the pools where starfish had been removed to the diversity in pools where he had let the starfish remain. By removing starfish from some pools, what global change driver was Robert Paine investigating? overexploitation pollution climate change invasive species habitat lossarrow_forwardIn terms of trophic levels and energy, why do you suppose that there are not many top predators around?arrow_forward
