Where do plants get the carbon they use to make organic molecules?

Plants get the carbon they use to make organic molecules from carbon dioxide in the air through the process of photosynthesis. During photosynthesis, plants use sunlight to convert carbon dioxide into glucose and other organic compounds, which they use as building blocks for growth and energy.


What is the source of all energy for photosynthesis?

Sunlight!!! Although the above answer is correct, I guess there could be some explaining. You see, sunlight powers and starts the photosynthesis. Plants absorb carbon dioxide and release oxygen. Here's something that will help, sunlight is the source for all energy. Even us. We need to breath to live. Plants give us oxygen to breath. Plants use sunlight to give us oxygen. So, the answer to any question involving the source of anything is always sunlight.
