can you answer all the questions
Certainly! Here are the answers to all the questions:
Question 8: The (bottom) green box in the model represents producers that carry out photosynthesis to make carbon-rich sugars.
Answer: c
Question 9: The process represented in the model is photosynthesis, where plants use sunlight, water, and carbon dioxide to produce glucose and release oxygen.
Answer: b
Question 10: The process represented in the model is respiration, where organisms break down glucose to release energy and carbon dioxide.
Answer: d
Question 11: The process represented in the model is combustion, where organic matter is burned to release energy and produce carbon dioxide and other gases.
Answer: c
Question 12: The process represented in the model is decomposition, where organic matter is broken down by fungi and bacteria into simpler compounds and carbon dioxide is released.
Answer: a
Question 13: The process represented in the model is photosynthesis, where carbon dioxide is taken in by plants to produce glucose and release oxygen.
Answer: b
