1) How long ago were fossil fuels created?

2) Algae grown in open pond systems are susceptible to invaders, what are they and
how do they impact the algae?

3) What are some of the resource requirements for open pond marine algae
production?

4) What are the advantages of using wastewater in marine algae growth?

How long were fossil fuels created?: long before the dinosaurs even ruled the world.

Algae grown in open pond systems are susceptible to invaders, what are they and

how do they impact the algae? Algae cultivation takes place in large ponds, or in enclosed systems enhanced with CO2. Algae cultivation has many commercial and industrial uses and looks to be a promising long-term sustainable source of biomass and oils for fuel, food, feed and other co-products. Algae have evolved to produce and store energy in the form of oil. They are more efficient than many other natural or engineered

What are the advantages of using wastewater in marine algae growth?: Idk sorry

I really hopes at least have of this helps :D
