Explain photosynthesis as the process by which plants use light energy to convert carbon dioxide and water into glucose and oxygen, and describe how mineral nutrients are absorbed through roots
A first look
This shelf is still being planted — the questions are being written and checked. Come back soon. A Skill needs at least 5 checked questions before it opens here.
Question 1 of 3
Read the passage below. "Plants use photosynthesis to convert carbon dioxide and water into glucose and oxygen using sunlight. The glucose provides chemical energy for the plant and can be transferred to herbivores when they eat the plant. When organisms respire, they break down glucose, releasing carbon dioxide and water back into the environment." Which statement best explains how photosynthesis contributes to the cycling of matter and the flow of energy in an ecosystem?
Question 2 of 3
A sealed terrarium contains a flowering plant, a rabbit that eats the plant’s leaves, and a hawk that eats the rabbit. Over time, the terrarium’s atmosphere remains stable, and the organisms continue to grow. Which explanation best describes how photosynthesis contributes to both the cycling of matter and the flow of energy in this closed system?
Question 3 of 3
Liam is studying how his sunflower seedlings grow. He learns that the green pigment in the leaves, chlorophyll, helps the plant use sunlight. Which sentence best explains the role of chlorophyll in this process?
