Question

open - ended questions: answer the following questions in complete sentences. 1. explain how photosynthesis and cellular respiration are connected in the cycle of energy in living things. 2. describe one key difference between aerobic and anaerobic respiration.

Explanation:

1. Photosynthesis uses light energy to convert carbon - dioxide and water into glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon - dioxide, water, and energy (ATP). The oxygen and glucose from photosynthesis are used in cellular respiration, and the carbon - dioxide and water produced by cellular respiration are used in photosynthesis, forming an energy cycle.
2. Aerobic respiration requires oxygen and produces a large amount of ATP, while anaerobic respiration occurs in the absence of oxygen and produces less ATP.

Answer:

1. Photosynthesis produces glucose and oxygen which are used in cellular respiration. Cellular respiration produces carbon - dioxide and water which are used in photosynthesis, creating an energy cycle.
2. Aerobic respiration needs oxygen and yields more ATP, whereas anaerobic respiration occurs without oxygen and yields less ATP.
