5. nutrient, forms the backbone for all macromolecules in living things
9. anything that has mass and takes up space, makes up everything
12. third step of aerobic respiration NADH and FADH2 from earlier reactions are used to make 32 units of atp
14. all the soil on earth
15. pigment in chloroplast, used to trap light energy in photosynthesis
20. describes a situation in which oxygen is not present
22. Organelle, site of photosynthesis
24. process of breaking down glucose to make ATP, starts with c6h12 and o2
26. all the gases surrounding earth
27. Adenosine diphosphate, uncharged energy storage with 2 phosphates

1. type of organism that breaks down biotic compounds into abiotic compounds, recycles
3. organism that is able to make its own food, base of food chain
4. nutrient, used in proteins and nucleic acids. must be fixed for living things to use, often limited
6. reactions second step of photosynthesis, uses energy in atp snd nadph to make glucose (c6h
