Question

Use the diagram to answer the next question. 35. There are 1,500kg of energy in the producers in this ecosystem. How much energy is available to the snake? a) 15,000 kg b) 15 kg ) lkg d) 1.5kg e) 0.15kg 38.A few birds of the founder hummingbird population feed on white-flowered plants, which they pollinate ower to flower, brushing against the flowers as they feed. If on this island, a deadly would correctly predict that if the disease became a disease kills most of the red-flowered plants, you permanent part of the environment, then over thousands of years. a) white-flowered plants would become more abundant than red-flowered plants. b) feedi ing hummingbirds would pollinate the red-flowered plants less frequently than the white flowered plants c) hummingbirds that prefer white flowers would become more common than hummingbirds that prefer red flowers d) all of the above would occur e) (a) and (c) are the only correct answers Use the following information to answer the next 4 questions: Gifblaar is a plant that grows in South Africa. European cattle that were brought to South Africa in the 1830s ate the leaves of the plant and died. Scientists later learned that the plant produces fluoroacetic acid, which interferes with an enzyme in the Krebs cycle. 39. You would correctly hypothesize that gifblaar plants now produce fluoroacetic acid because their ancestors a) produced fluoroacetic acid and produced fewer offspring than those that did not produce fluoroacetic acid b) evolved ways to produce more carbon dioxide in the Krebs Cycle than other plants c) produced the acid and fewer were eaten than plants that did not produce fluoroacetic acid d) produced fluoroacetic acid and produced more offspring than those individuals that did not produce fluoroacetic acid e) Both (c) and (d) are correct hypotheses 40. You would correctly predict that animals that eat gifblaarthan those that do not eat it. a) gain more weight d) consume more oxygen e) produce more carbon dioxide b) produce less ATP c) produce more ATP
