Match the equations with the correct process. A - oxygen + water ---> glucose (sugar) + carbon dioxide + ATP B - glucose (sugar) + oxygen ----> carbon dioxide + water + ATP C - glucose (sugar) + oxygen + sunlight ----> carbon dioxide + water D- carbon dioxide + water + sunlight -----> glucose (sugar) +oxygen

• A - photosynthesis and C - respiration
• B - photosynthesis and D - respiration
• C - photosynthesis and A - respiration
• D - photosynthesis and B - respiration

How does oxygen escape from the leaf into the air?

• The oxygen goes out through the stoma in the leaf surface.
• The oxygen travels down the stems through the phloem tissues and goes out the root cells.
• The oxygen attaches to the sun's energy as it is released from the leaf.
• The oxygen is released when animals eat the leaves.

When humans impact the carbon cycle, an imbalance can occur. Select the example below which demonstrates a carbon imbalance caused by human activity.

• Carbon released by animals increases CO2 levels in the air.
• Mining and burning of fossil fuels turns stored carbon into CO2 into the air.
• Photosynthesis by plants and algae removes CO2 from the air.
• CO2 absorbed by the oceans creates carbonic acid which dissolves limestone.
