The food web below represents the organisms of a large community. The arrows show the direction of energy flow in the system. Calculate the amount of energy that will be available for the Baleen Whale after the Krill consumed 200 J of phytoplankton. The Krill used 67 J for cellular respiration and 100 J for feces. Justify your response.
Imagine a disease spreads among the desert grasshoppers and most of them die off. How would the grasshoppers’ disappearance affect the food chain and its organisms? Remember that the grasshopper eats some organisms and is also eaten by other organisms.
What group of organisms make their own food? A. Autotrophs B. Producers C. Phototrophs D. All of the options are correct.
A microbiology professor noted that in the fall when the apples are ripe, her cow, appropriately called Tipsy would stagger home from the apple orchard at night. What possibilities could you offer to explain Tipsy's behavior? Why don't you feel this way when you consume apples from the grocery store? – this has to do with alcohol fermentation, remember the apples that are ripe fall from the trees and microbes begin to break them down.
Look at the picture. Which statement below best describes how the organism in the picture gets the food it needs?a) it gets energy by consuming other plants as food. b) it gets energy by breaking down dead material. c) it gets energy by consuming animals as food. d) it changes sunlight, carbon dioxide and water into food and oxygen.
Cattle are able to survive on a diet consisting almost entirely of plant material because (pick all that apply) they are autotrophic. they manufacture all 15 amino acids out of sugars in the liver. cattle, like rabbits, re-ingest their feces. cattle saliva has enzymes capable of digesting cellulo they have cellulose-digesting, symbiotic microorganisms in specific chambers of their stomachs.
Use the information to answer the following question. Animals need nitrates (NO2) to make protein. Nitrogen (N2) is found in the air, but not in a form that animals can use. Through the nitrogen cycle, nitrogen in the atmosphere is converted to nitrates. Which of these functions of bacteria in the nitrogen cycle most directly affects plants and animals in the food chain? A.Bacteria are important because they produce the nitrates that animals need. B.Bacteria are important because they transform nitrogen into nitrates that animals need. C.Bacteria are important because they allow plant roots to absorb nitrates from the air. D.Bacteria are important because they break down plant matter that competes with living plants for nitrates.
Which of the following requires aerobic conditions? Question 7 options: A) nitrogen fixation B) sludge digestion C) primary sewage treatment D) secondary sewage treatment
Evaluate the salt tolerance of the above organisms.a. Tolerates very little salt:b. Tolerates a broad range of salt concentrations:c. Grows only in the presence of high salt concentration:
write an evaluation and discussion using the data and relate to answer the hypothesis. Hypothesis: The garlic cloves wrapped in biodegradable paper and foil will degrade gradually, however, the cloves without packaging will degrade at a faster rate. This is because the wrapped cloves are not being exposed to factors which affect biodegradation such as light and oxygen.
