Answer:
c
Explanation:
protons are the atomic number which define an element
The possible structures with 6-C Chain and 1 double bond i.e. the isomers are 2-methylhex-2-ene , 3-methylhex-2-ene , 4-methylhex-2-ene , 5-methylhex-2-ene , 2-methylhex-3-ene , 3-methylhex-3-ene , 4-methylhex-3-ene , 5-methylhex-3-ene , 2-methylhexene , 3-methylhexene , 4-methylhexene , 5-methylhexene .2-methylene hexane , 3-methylenehexane .
These all are functional group isomers.
<h3>isomers :</h3>
same molecular formula but different physical and chemical properties .
<h3>Positional isomers :</h3>
same molecular and chemical formula but different in position of the functional group .it is a structural isomerism .
<h3>functional isomers :</h3>
same molecular formula but different functional groups attached to the main ring.

Answer:
Producers, consumers and decomposers
Explanation:
Producers can make their own food by capturing the sun's energy, but consumers and decomposers can't. Consumers need to eat other organisms to obtain energy. Decomposers are like the recyclers of nature. They obtain energy for their own needs while returning simple molecules to the environment.
Explanation:
Cr=35.880/51=0.73≈0.7
P=21.076/31=0.67≈0.7
O=43.543/16=2.71
Divide each by 0.7 u get
Cr=1 ,P =1, O=4
Empirical formula is CrPO4
