Whenever an object is falling, its potential energy 
is decreasing and its kinetic energy is increasing.
Olivia's potential energy is decreasing and her kinetic energy 
is increasing as she moves toward the right side of the picture, 
all the way from W, through X, to the bottom of the arc.

Answer:
Photosynthetic organisms 
Explanation:
The electromagnetic energy of sunlight is converted to chemical energy in the chlorophyll-containing cells of photosynthetic organisms. In eukaryotic cells these reactions occur in the organelle known as the chloroplast
