Carbon cycle activity carbon cycle Try the quiz! Carbon cycle - vision learning

// __Carbon Story__ // // I am in the atmosphere, two hydrogens are with me, we see a lot of our friends come and go from here, we fear we are next, that fear was well founded. We fell from the sky and was absorbed by a leaf - I not sure what type though, I’m transformed by the chloroplasts who used the radiant sunlight to gain energy. It feels weird and it hurts as I’m transformed. I am now sugar and I then find myself being part of tree. It’s a great oak tree that probably will live for years. I feel strong. I smell the pollen in the air it’s spring. I hear birds make nests, and tweet. I see the bird’s children grow and come back with their own children. The butterflies lay their eggs and they hatch into caterpillars who eat the leaves of my home. I watch many come to my oak seeking shelter, food and more. One day, I smell the frighting smoke. I feel the heat burn at the bark, I taste the fumes, I feel that I’m in pain I’ll have to transform again, what a disappointment - I really began to enjoy it here. I’m thrust back into the sky as the smoke carries me up, back to begin again to live a life in the sky. Maybe I’ll see the hydrogens again. You are probably thinking what are you? Well, I will answer that, I am a Carbon Atom. //
