BIO 201 Study Guide - Final Guide: Carbon Fixation, Sporophyte, Gametophyte
Document Summary
Energy in the bonds of water, air, nutrients - but, energy not accessible to the plant; sosunlight still remains as the main energy source for a typical plant. Plants get their mass from carbon dioxide in the air; minerals/nutrients from the soil are utilized, but most soil still remains in the pot. In a closed system, matter cannot be either created or destroyed. Humans get matter from plants + herbivores = incorporates carbon into tissue. When we lose weight - we"re breathing out carbon dioxide. Plants get matter from the air through carbon fixation. Dying does not require energy - bonds are still there - so most of the energy is there. Decomposition breaks down the bonds and now the energy is within the fungi. Consistency index = (minimum number of changes/actual number of changes) Do not ever use the data table to find the actual number of changes 0.
