thomaster · Answer

carbon monoxide is nowhere in the list.
how is the method called which algae use to produce food?

anonymous · Answer

photosynthesis right?

thomaster · Answer

Yes. 
What is needed for photosynthesis?

anonymous · Answer

C.	sunlight, water, oxygen, and chlorophyll

thomaster · Answer

Nope. oxygen isn't needed. oxygen is a product of the reaction.
This is the equation for photosynthesis:

$\sf\large 6CO_2+6H_2O ~~\underrightarrow{sunlight}~C_6H_{12}O_6+6O_2$
This reaction takes place in chlorophyll so that one is needed too.

anonymous · Answer

so my answer isnt C?

thomaster · Answer

No. when something is a product of a reaction, it's not needed for the reaction. The things you need are called the reactants and they're on the left of the arrow.

anonymous · Answer

lol its B

thomaster · Answer

I wouldn't say the answer is B. I'd say the answer is water, sunlight, carbon dioxide, and chlorophyll. Saying it's B is like you don't care about learning the material and are just guessing the answer. Do you actually wan't to learn this stuff or are you here only for the answers? Because it's like you post every single question you've got to answer :S

anonymous · Answer

lol I have like 45 questions to do for homework lol its not easy, and i post not even half of them, i just like to make sure my answers are correct:)

thomaster · Answer

Oke, that's alright. But try to explain more why you think it's A or B or whatever. You're just saying "I think it's C" or "wouldn't it be D?"
Explain why you think that, so other people can correct you if you're thinking wrong. That's the reason why I keep asking questions to you. I could tell you all the answers very easily but you won't learn anything from that.
