Scientists examined the interactions between bacteria and two species of protozoa,Uronema sp. and Euplotes sp., found in the bays and inlets of coastal California. Anexperiment was designed that modeled the ecosystem and measured the amount ofbacteria and carbon that were ingested by the protozoal species, as shown in the datatable. Bacteria with labeled glucose were incubated with these two species of protozoa.The number of bacteria, carbon ingested, and carbon exuded from the protozoa were thenmeasured.Which of the following explains how the difference between ingested and exuded carbonrelates to the energy in the aquatic ecosystem?ProtozoaBacteriaBacterialExudedIngestedCarbonBacterial(x107IngestedCarbon-ih-1)(ngC l-1h-1)(ngC l-1h-1)Uronema172.2034,4603,067sp.Euplotes50.8210,170305sp.The protozoa hydrolyzed the ingested carbon, resulting in an increase in energy within theecosystem.The protozoa decomposed the ingested carbon, resulting in an increase in energy withinthe ecosystem.The protozoa hydrolyzed the ingested carbon, resulting in no net change to the energywithin the ecosystem.The protozoa decomposed the ingested carbon, resulting in no net change to the energywithin the ecosystem. The island of Isle Royale in Lake Superior has historically contained both moose andwolves. In recent years, the number of wolves has dwindled, leaving few predators for themoose. This has led to a large increase in the moose population on the island. Thefollowing information is from 2018. Using this information and the equation shown, thegrowth rate for the moose population on Isle Royale can be calculated. Based on thecurrent population and the growth rate, what type of growth model would be expected?K = 2,000 mooseN = 1,500 mooseRmax = 0.5where:dt = change in timeN=population sizeax =maximum per capita growth rate of populationK= carrying capacityA logistical growth model would best represent this population because the moose populationwill decrease over time.An exponential growth model would best represent this population because there are fewpredators for the moose on this island.A logistical growth model would best represent this population because the increase in thenumber of moose would level off over time.An exponential growth model would best represent this population because the moosepopulation has not reached its carrying capacity and will continue to grow over time.

Protozoa engulfe bacteria and hydrolyze the carbon obtained. They pursue heterotrophic mode of…

Scientists examined the interactions between bacteria and two species of protozoa, Uronema sp. and Euplotes sp., found in the bays and inlets of coastal California. An experiment was designed that modeled the ecosystem and measured the amount of bacteria and carbon that were ingested by the protozoal species, as shown in the data table. Bacteria with labeled glucose were incubated with these two species of protozoa. The number of bacteria, carbon ingested, and carbon exuded from the protozoa were then measured. Which of the following explains how the difference between ingested and exuded carbon relates to the energy in the aquatic ecosystem? Protozoa Bacteria Bacterial Exuded Ingested Carbon Bacterial (x107 Ingested Carbon -ih-1) (ngC l-1h-1) (ngC I-th-1) Uronema 172.20 34,460 3,067 sp. Euplotes 50.82 10,170 305 sp.
