Overview : life is work

• •Living cells require energy from outside sources

  
  

• •Some animals, such as the chimpanzee, obtain energy by eating plants, and some animals feed on other organisms that eat plants

ATP : chemical energy

•Energy flows into an ecosystem as sunlight and leaves as heat

•Photosynthesis generates O2 and organic molecules, which are used in cellular reactions

•Cells use chemical energy stored in organic molecules to regenerate ATP, which powers work

questions
