The Energy Chain

Did you know that bears climb trees because of the sun?
Sun Plant Bear Bear Climb
AEnergy from the sun creates wind and rain. The wind helps scatter seeds for new plant and tree growth. Rain provides needed water.
BTrees and plants grow because they take energy from the sun and convert it to CHEMICAL ENERGY through a process called PHOTOSYNTHESIS. The chemical energy is stored in the plant as potential energy.
CWhen a bear eats a plant, the stored energy from the plant is converted to muscle energy...

...and the bear can climb a tree! So the sun allows the tree to grow and gives the bear the energy to climb it!
