| Description: Autotrophs Produce their own food from the sun’s energy Photosynthesis Turning light energy from the sun into chemical energy - Chloroplasts = organelles where photosynthesis occurs - Contain chlorophyll = a light-absorbing pigment - Light reaction = splits water by using solar energy - Calvin cycle = links carbon atoms from carbon dioxide into sugar (glucose) - Photosynthesis: 6CO2 + 6H20 + the Sun’s energy ----------> C6H12O6 + 6O2 - Organisms use chemical energy from photosynthesis - Oxygen is used to convert glucose into water + carbon dioxide + energy - Heterotrophs = organisms that gain energy by feeding on others - Animals, fungi, microbes - Cellular Respiration: C6H12O6 + 6O2 ------------> 6CO2 + 6H20 + energy Picture Stats: Views: 402 Filesize: 67.94kB Height: 799 Width: 650 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=35609 |
