Directions: construct a diagram that includes all the relevant processes between the ecological cycles (water carbon and nitrogen). Your project should show imagination and creativity. All aspects of each process should be shown and labeled:
Carbon:
• Photosynthesis
• Cellular respiration
• Decomposition
• Burning of Fossil Fuels

(Accurate labeling and arrows showing movement throughout the ecosystem)

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.

im not intirely sure but i think the anwser is d relative humidity

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
