Algae is the primary photosynthesising agent on earth. Seaweed also photosynthesises (some species at least, I'm not sure if there are others that don't), so yes, both of them do produce oxygen from carbon dioxide.
Oxygen (O2)
trees and kelp because trees take in the dirty oxygen and puts out the clean oxygen and the kelp i was researching kelp and i saw that kelp helps and makes oxygen.

Lack of oxygen.
Flowers do not give out oxygen, the green parts of a plant give out oxygen when the are engaged in photosynthesis.
animals eat off of it
Most leafy plants and trees give off oxygen

Why is it important that plants give off oxygen during photosynthesis
