Trees are massive, heavy plants containing lots of cellulose (a type of carbohydrate). Where do trees get all the carbon to grow so big? Water, Sun, Air, or Soil?

Dead organic matter commonly decomposes in a pattern that follows a negative exponential curve. Scientists wanted to compare the decomposition rates of leaves from cherry trees and maple trees. The scientists placed bags of leaves from each type of tree into a stream and retrieved the bags over time. The scientists repeated the experiment three times. The scientists calculated and graphed the mean amount of litter remaining of each leaf type at all time points. When plants decompose, the dead plant matter first leaches substances such as salts, sugars, and amino acids. After this leaching, one compound left behind is lignin. Lignin gives leaves their toughness and resists decomposition.

O Since the maple leaves decompose the slowest, they have a greater amount of lignin. O Since the…
