Bunicellular.dinoflagellates are unicellular or multicellular, producers, and autotrophs, and apple trees are multicellular, producers, and autotrophs. all plants have numerous cells in them, so they can never be unicellular. the remaining characteristics they share with less complex organisms such as dinoflagellates.

Alright! 1. the carbon that is found in the trees or plants are eaten by animals that are vegetarians or omnivores(eat plants and meat).2. the animal might excread the waste(basically whatever the body did not need)with can then decompose and make the soil have carbon.  3. the animal also can breath in the carbon that is found in the air.  4. the carbon molecule can also be released by chemical reaction like the fire in the picture.  5. carbon can also be found in bodies of water.  hope this ! : )
