The organism that receives its energy directly from the sun is a plant.

Here's why:

* Photosynthesis: Plants use a process called photosynthesis to convert sunlight into chemical energy (sugars) that they use for growth and other life functions.

* Producers: Plants are considered producers in the food chain because they make their own food.

While other organisms may benefit from the sun's warmth, only plants can directly use its light energy for their primary source of sustenance.
