Question

examine the diagram of the carbon cycle below and use it to answer the question that follows
question: what process is happening at point b?
aerobic cellular respiration
anaerobic cellular respiration
none of these processes are happening here
photosynthesis

Explanation:

At point B, the process involves the production of lactic acid, ethanol, or other similar by - products from organic compounds (like glucose) without the use of oxygen. This is characteristic of anaerobic cellular respiration, where cells break down organic matter to produce energy in the absence of oxygen, and by - products such as lactic acid or ethanol are formed. Aerobic respiration requires oxygen and produces carbon dioxide and water, while photosynthesis is the process of converting carbon dioxide and water into organic compounds using light energy, which is not the case here.

Answer:

Anaerobic cellular respiration
