Organisms' Energy Sources

Energy Sources for Organisms

Organisms use different processes to obtain the energy that they need to perform cellular functions. Some organisms rely on photosynthesis to convert sunlight into energy-rich molecules, while others consume organic matter for energy. One such example is the polar bear and orange tree, which utilize different energy sources to survive in their respective environments.

Energy Source for Polar Bears and Orange Trees

Glucose is used as an energy source for polar bears and orange trees. Glucose is a simple sugar that is produced during photosynthesis in plants like orange trees. The glucose is then used as a source of energy by the orange tree for growth and metabolism. In the case of polar bears, they obtain glucose indirectly by consuming other organisms that have already processed glucose through plant consumption.
