How does the energy needs of a maple tree might differ from those of a squirrel?

A maple tree primarily relies on photosynthesis to convert sunlight into energy, using carbon dioxide and water to produce glucose and oxygen. In contrast, a squirrel has a higher metabolic rate and requires energy from food sources, such as nuts and seeds, to sustain its activities, including foraging and maintaining body temperature. While the tree's energy needs are largely dependent on sunlight and environmental conditions, the squirrel's energy needs are influenced by its activity level and the availability of food. Thus, their energy acquisition methods and requirements are fundamentally different.
