Question

where do the carbons in the carbohydrates (sugar) that are made during photosynthesis come from? Options: Soil nutrients, Carbon dioxide, water, oxygen

Answer 1

The carbons in the carbohydrates (sugars) that are made during photosynthesis primarily come from **carbon dioxide**. During photosynthesis, plants take in carbon dioxide from the atmosphere, and using sunlight as energy, they convert it into glucose (a type of carbohydrate) and oxygen.
