First! Ask yourself... who, what, when, where
I think the answer is A im sorry if its not right
The correct answer is A. Petroleum is not a raw material for the production of biofuels. From the name itself, biofuels are obtained from biomass. Biomass are organic materials for example are the choices given in B, C and D.
Aerobic respiration is the process by which cells produce energy with the use of oxygen. In this analysis, we could suggest that compared to those organisms that are 1000m deep, those that are on the surface can produce energy more efficiently. Hence, they can greatly reproduce doubling their size within a small period of time.
The adaptation that best fit for those that are in 1000m deep is anaerobic respiration.
