Plants can get their energy from the sun by just sitting there, we have to go search for it, hunt, etc. Why didn’t we evolve to be green and get our energy from the sun. –Why aren’t we green? Copyright © 2010 Ryan P. Murphy

Answer! Because photosynthesis only produces a small amount of energy. –We need lots of sugar to run, jump, and live our very busy and active lives. Copyright © 2010 Ryan P. Murphy Plants are less active.

Respiration – The plant burns the sugar to make energy. ChloroplastsMitochondria

Remember: Producers create the sugars, then consumers use these sugars. –Plants harness the energy from the sun so we can live. “I love your sugars that you produce from photosynthesis.” Copyright © 2010 Ryan P. Murphy

Biology October 22, 2014 Copy and answer the following EQ into your science notebook. EQ: How is nitrogen cycled through the Earth? The movement of nitrogen between the atmosphere, biosphere, and geosphere in different forms is called the nitrogen cycle.

Nitrogen Cycle: The circulation of nitrogen. Nitrogen Cycle: The circulation of nitrogen. Copyright © 2010 Ryan P. Murphy plant decay ( fungi and bacteria) ammonification nitrification Nitrogen-fixing bacteria

Lightning can convert

Rain and precipitation bring the atmospheric Nitrogen to the ground.

Lightning can convert And nitrogen mixes with rain

Lightning can convert And nitrogen mixes with rain Bacteria fix nitrogen into NH 3, NO 2 -, NO 3 -

All life requires nitrogen-compounds, e.g., proteins and nucleic acids. Air, which is 79% nitrogen gas (N 2 ), is the major reservoir of nitrogen. But most organisms cannot use nitrogen in this form. Plants must secure their nitrogen in "fixed" form, i.e., incorporated in compounds such as: –nitrate ions (NO 3 −) –ammonia (NH 3 ) –urea (NH 2 )2CO Animals secure their nitrogen (and all other) compounds from plants (or animals that have fed on plants).

Eventually, plants and animals die. Ammonia (NH3) / Decay / Waste

Lightning can convert And nitrogen mixes with rain Bacteria fix nitrogen into NH 3, NO 2 -, NO 3 - Animals get nitrogen by eating plants

Denitrifying bacteria can also change the NH 3 Nitrate back to N 2 Nitrogen gas

Lightning can convert And nitrogen mixes with rain Bacteria fix nitrogen into NH 3, NO 2 -, NO 3 - Animals get nitrogen by eating plants Decomposers break down nitrogen Nitrites NO 2 and Nitrates NO 3

Which is the bogus statement?

Four processes participate in the cycling of nitrogen through the biosphere. A.) Nitrogen fixation: Break apart N 2 so it can join to other atoms and be used. B.) Decay: Passes on through eating / waste. C.) Plants with the help of bacteria take up nitrogen. D.) Denitrification: Nitrogen is removed from air. Copyright © 2010 Ryan P. Murphy
