Henry is in the community investigating sources of chemical energy for his science experiment. Select the best examples of chemi
cal energy Henry can use. A gas station and people playing hopscotch
A squirrel eating acorns and a fire burning
Someone reading a book and eating a sandwich
Someone sliding down the slide and someone drinking water
Decomposers (organisms that break down dead producers and consumers and organic waste) obtain the energy they need to live from chemical bonds of the dead and waste-matter. The energy is transferred both to the decomposer (for growth and development) and to the ecosystem (as heat energy)
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
