Question

question 7 1 pts mariana eats an orange. which statement describes the ultimate source of the energy that her body receives when she digests the orange? the orange contains the energy - rich nutrients that it draws from the soil. the orange tree obtains energy from the nitrogen compounds and other compounds in fertilizer. the light energy that originates from the sun provides the energy to grow oranges, which contain macromolecules. organic matter, rich soil in which the orange tree grows, and adequate water all work together to generate the energy that can be derived from the orange. question 8 1 pts natasha is making a model of cellular respiration. her model shows the pathway followed when there is enough oxygen available. what does natashas model show? an aerobic pathway consisting of glycolysis and fermentation an anaerobic pathway consisting of glycolysis, the krebs cycle, and the electron transport chain an anaerobic pathway consisting of glycolysis and fermentation an aerobic pathway consisting of glycolysis, the krebs cycle, and the electron transport chain

Explanation:

For Question 7: The energy in oranges comes from the sun - light energy is used in photosynthesis by the orange tree to produce macromolecules. For Question 8: When there is enough oxygen, cellular respiration follows an aerobic pathway which includes glycolysis, the Krebs cycle, and the electron - transport chain.

Answer:

Question 7: The light energy that originates from the sun provides the energy to grow oranges, which contain macromolecules.
Question 8: an aerobic pathway consisting of glycolysis, the Krebs cycle, and the electron transport chain
