Document Summary

Spaces in soil allows for air and water, and space for animals. Photosynthesis : carbon dioxide + water -> (light energy) glucose + oxygen. Glucose contains co2, reflects the environment"s concentration of co2. Trees that die off will release the carbon dioxide they"ve absorbed back into the atmosphere. Primary succession: begins with a new environment with just a few rocks. Rocks > mosses > ferns > pines > beeches & maples. Secondary succession: when succession begins with an existing community of trees. Living trees > stumps > weed > aspen, beeches > returns to climax. Soil created from glaciers when a large block of ice drags along dirt and soil up to another region, allowing it to sustain life when temperature permits. Climax: consisting of ideal soil, water, and temperature conditions that support the growth of certain vegetation. Named after their main vegetation in that area. Boreal forest: long winters, short warm summers, and more precipitation.
