When you get hungry, what do you do? You might decide to raid the refrigerator or try to convince your mom to take you to a fast food restaurant. You do those things because you are a heterotroph (or consumer). Heterotrophs are organisms that need to get their energy from the foods they eat. Humans and animals are heterotrophs — so are parasites like fleas, ticks, and tapeworms!
Conifers, like other green plants, can't just reach in the fridge for a quick snack. They have to make their own food. Green plants are called autotrophs (or producer). Autotrophs use light energy from the sun to produce the food they need. To understand how this works, we need to learn about photosynthesis.
