Is a fuel produced by fermenting crops. a. ethanol b. biodiesel c. oil shale d. methanol

Correct A). Ethanol

Bio-ethanol is an alcohol which is produced by the process of fermentation of crops. It is mainly produced by the fermentation of carbohydrates such as starch, which is found in sugarcane, sweet potato, corn etc.

It is also produced from cellulose biomass, which is derived from the non-food source like grass and trees.

It is produced through a biological process like anaerobic digestion, rather than geological process, which is used for the formation of fossil fuel like coal, petroleum.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
