A rollercoaster car moves from left to right as shown. The car starts out with high velocity as it is launched at the gate and no additional energy is provided during the part of the roller coaster shown. Determine whether the car is gaining or losing kinetic and potential energy at each part of the rollercoaster.

Cellular Respiration
In comparing these two species, photosynthesis increases more rapidly in the presence of carbon dioxide for plants. The C4 species reaches a peak rate of photosynthesis at and the C3 species reaches a peak rate of photosynthesis at . This means that carbon dioxide concentrations in excess of will not increase the rate of plant growth or carbohydrate production for either species. The tropical C4 species grows more quickly. Since the photosynthesis reaction requires an equal number of CO2 and , this is adaptive for tropical environments.
