Which option is food (i. e., an energy source) for a plant? carbon dioxide that a plant takes in through its leaves

minerals that a plant takes in from the soil

water that a plant takes in through its roots

sugars that a plant makes

I'm pretty sure that it is the water the plant takes through its roots

Explanation:

Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means 'making out of light'. The foods are called glucose and starch. which is the process of making food for plants

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
