    So how do photosynthesis break down things? You know, for CO2 to become separated, there needs to be a separation.

      When we say that photosynthesis drives the movement of matter, we can interpret that this process is the key factor for the matter/atoms to move between organisms. For instance: If it wasn't for photosynthesis, plants wouldn't have sugar to grow, then herbivores wouldn't have anything to eat, and so it goes on to the food chain.

      In short words, it's thanks to photosynthesis that matter and energy in the form of sugars or other compounds can "travel" between various organisms (animals, plants, algae, fungus, etc) throughout the environment.

    For your information:

    Heterotrophs are organisms that eat other organisms to survive. E.g., humans, cows, lions, etc.

    Autotrophs are organisms that make their own food from natural processes like photosynthesis.

    I hope this helped you distinguish between Organisms that make their own food and ones that don't.
