1: TRUE or FALSE? Elements are pure types of matter.
2: TRUE or FALSE? Atoms are made from molecules.
3: TRUE or FALSE? Chlorophyll is needed for cellular respiration.
4: TRUE or FALSE? Matter and energy flow through food chains.
5: TRUE or FALSE? Chemical compounds contain at least two types of atoms.

False for 3 and 4.
true for 5.
are my answers correct?
"Atoms make up molecules."
So how could number 2 be true?
