Study Notes
Photosynthesis and Respiration
- Plants capture carbon and give off oxygen through a process called photosynthesis.
- Plants use light energy to make large polymer molecules.
- They build up new plant material using glucose.
Cellular Respiration
- Plants and animals take in oxygen and rejoin it with carbohydrates, returning carbon dioxide to the atmosphere through a process called cellular respiration.
- Animals use oxygen to make their molecules.
Biomolecules
- Plants make polysaccharides from joining sugars and DNA.
- Animals break food polymers back into small molecules through a process called digestion.
Energy and Matter Cycles
- The natural cycle in which matter is cycled using energy from the sun is called the biogeochemical cycle.
- All living things build up large polymer molecules from small molecules through a process called anabolism.
- Plants and animals obtain energy for their living processes from glucose.
