GOOD MORNING  GET YOUR NOTES FROM LAST CLASS OUT PLEASE  AT SOME POINT BY THE END OF CLASS SIGN UP FOR SCHOOLOGY ACCESS CODE: NMTQV-7N82K ACCESS CODE: NMTQV-7N82K

Material Cycles The flow of an element through the physical environment and living tissues of an ecosystem

What is Recycled?  More than 30 chemical elements are cycled through the environment by material cycles  Some examples are : Water Water Carbon Carbon Nitrogen Nitrogen Phosphorous Phosphorous

Water cycle  Water ______________ into clouds.  Water falls as _________________.  ________ & _________ forms fresh lakes, rivers, ponds, streams, and ground water.  ___________ take up water  Water returns to the atmosphere through the process of _____________ & ________________. condenses precipitation Runoffseepage Roots evaporation transpiration

Carbon Cycle 1. In the atmosphere as carbon dioxide(CO 2 ) 2. In the ocean as dissolved CO 2 3. As calcium carbonate, which is part of bones and shells  Where is Carbon found?

Carbon Cycle  Plants take in CO 2 and use the carbon to make carbohydrates during photosynthesis.  Carbon (in the form of carbohydrates) is passed along the food chain.

Carbon Cycle  Carbon is released into the atmosphere by volcanic activity, respiration, burning of fossil fuel (industry), and by decomposition of organic matter.

Nitrogen Cycle  Nitrogen is required to make amino acids which are used to build proteins

Nitrogen Cycle  Special bacteria which live on plant roots, take N 2 from the atmosphere and convert it to ammonia (NH 3 ) in a process called nitrogen fixation  Other bacteria break down ammonia from decaying organisms into nitrite (NO 2- ) or nitrate (NO 3- ) which is used by producers and consumers

The Nitrogen Cycle N 2 in Atmosphere NO 3 - Nitrate & NO 2 - Nitrite NH 3 Ammonia

Bacteria with plant roots

INORGANIC  a (1) : being or composed of matter other than plant or animal :  a (1) : being or composed of matter other than plant or animal : EX. mineralEX. mineral (2) : forming or belonging to the inanimate world EX. mineral

Phosphorus Cycle  Found mostly as inorganic compounds (minerals) 1. On land in rock and in soil 2. In the ocean as sediments Calcium Carbonate Shell Phosphorus rich Sediment

Phosphorus Cycle  Producers are able to bind phosphate into organic compounds (usable to us).  The producers get eaten by consumers who then acquire the phosphorus for their own use.  What do they use it for???…

Phosphorus Cycle  Phosphorus is essential to life because it is part of DNA RNA & ATP DNA RNA & ATP ATP = ENERGY! ATP = ENERGY!

Class Activity  Work with our partner to complete the Material Cycle cooperative activity  There are four diagrams that you need to complete  When your group is finished with one diagram, bring it up to your teacher for verification  You can use your notes for reference
