B--The amount of carbon on Earth cycles, gradually increasing as it moves up the food chain, and decreasing until the next phase of the cycle.

C--Carbon flows through the food chain as animals eat it, then decomposes and is permanently removed from the system when the food chain is complete.

D--Carbon enters Earth's atmosphere when animals exhale, then moves into space where its amount steadily increases, and finally moves back into Earth's atmosphere to be used again

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

i think that c)gold was found there

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
