Example text

Atmospheric carbon enters land ecosystems when carbon dioxide is captured through photosynthesis by green plants or ­cyanobacteria (fig. 4). Photosynthesis (literally, “making with light”) uses solar energy to transform carbon ­dioxide and water into glucose, which is used by plants to build ­complex carbon molecules. Oxygen gas is released into the atmosphere ­during photosynthesis. This reaction is summarized as: carbon dioxide 1 water 1 sunlight (energy) → sugars 1 oxygen. Aerobic respiration reverses the equation: it breaks apart complex carbon molecules in the presence of oxygen and releases carbon dioxide, water, and energy.

A grid of mutually beneficial connections between trees and neighboring plants that gives the concept of “plant communities” new meaning. Fungi that surround and attach to the outside of a root are called “ectomycorrhizal” and are commonly associated with forest trees.
