13 Ansh Guglani C. BIOGEOCHEMICAL CYCLES 1. Chemicals moving between the Geological and Biological components of an ecosystem 2. Cycles: WATER, CARBON, NITROGEN, PHOSPHOROUS, etc. Water | Photosynthesis | Phosphorus Evaporation: liquid b gas | uses H 2 O! | Why is it different? Condensation: clouds |------------------- | answer: does not exist in the Transpiration: water evaporates | Respiration | atmosphere (comes from rock) from plant leaves | releases H 2 O! | PO 4 3 B phosphate ion – see handouts/ essays VIII. Biosphere: includes all the ecosystems on Earth (thin skin of Earth where all known life exists). A. Biomes: a major type of Terrestrial (land) ecosystem 2. Named based on dominant Vegetation 3.
