Describe the path of energy from the sun to you using all the vocabulary terms in the lesson. which are ecosystem, photosynthesis, autotroph, heterotroph, chlorophyll

Photosynthesis takes place in all ecosystems.  Without it we would not be able to survive. Photosynthesis starts with plants. Plants are autotrophs which means they make their own food. During photosynthesis, plants take in sunlight, carbon dioxide (CO^2), and water during photosynthesis.  They give off glucose and oxygen. Plants have chlorophyll in them which gives them their green color.  Heterotrophs eat other living things to get energy. (If you want to go more into depth you can say this: Heterotrophs take in the glucose and oxygen.  This is called cellular respiration.  The products of cellular respiration are water, ATP (energy), and CO^2 which than leads you back to photosynthesis) Hope this helped! :)

Particle exchange energy though elastic collision , hope this .
