yes of course
Algae and other plants make their own food from sunlight, so they are producers.
Yes. The growth of algae in ocean water is limited by their need for carbon dioxide and sunlight.
no
Algae is biotic because it is a plant and plants need water/sunlight to grow. Save
working theory
It prevents sunlight from entering the aquarium which your fishes need an appropriate amount of sunlight to keep healthy everyday
It depends upon what kind of algae you are referring to. In general, most algae that humans interact with (the green stuff in pools and lakes, the symbiotic lichen algae on trees, etc.) do require oxygen, although aquatic algae derive their oxygen from the dissolved oxygen in the water.
They Get it from sunlight.

Marine algae are photosynthetic. At depths below 200m there is very little sunlight which would make photosynthesis extremely difficult.
yes of course
Lack of sunlight or nutrients. Algae is essentially a type of plant. Think about typical household plants, if they don't have water, soil, or sunlight, they will die. But algae, unlike household plants, typically live in a body of water, so a lack of water normally is not a cause of death for them. Normally, algae die because there is not enough sunlight or nutrients, possibly because of an algae bloom (too much algae that use up sunlight and nutrients).
Sunlight, obviously; it will consume us all.
Algae depend on sunlight to carry out photosynthesis. There is not enough sunlight below 200 meters.
