For your first question regarding the typical percentage of energy loss in transfers from one trophic level to the next:
**d) 90%** is the correct answer. In general, only about 10% of the energy is transferred to the next trophic level, meaning that approximately 90% of the energy is lost, mostly through metabolic processes as heat.
For your second question about the oxygen and carbon dioxide exchange during photosynthesis and respiration:
**a) keep a stable level of carbon dioxide and atmospheric oxygen** is the correct answer. Photosynthesis consumes carbon dioxide and produces oxygen, while respiration uses oxygen and produces carbon dioxide, helping to maintain balance in the ecosystem.
**d) 90%** is the correct answer. In general, only about 10% of the energy is transferred to the next trophic level, meaning that approximately 90% of the energy is lost, mostly through metabolic processes as heat.
