2. Energy flows through Earth's spheres and changes along the way. (2 points) a. Fill in each blank with the type of energy being described.
The sun gives off energy, which enters the atmosphere. Plants absorb
some of the energy and perform photosynthesis to convert it into
energy in the form of sugars. Plants and the animals that eat them then turn that
energy into a different form of
energy, in the form of ATP. When plants
and animals use the energy, it becomes
energy.
b. Describe how energy is conserved in these systems.
