Mainly soya and sugar cane.
They can be from a variety of naturally occurring substances. Most commercial biofuels are manufactured from grain plants. But things such as adipose tissue could make biofuel, as well. In Sweden, some several thousand dead rabbits were supposed to be converted into biofuel, for example.
Using plants, trees and any vegetation to make biofuel has let to an unfortunate consequence. The price of some staple foods has gone up, and their availability has decreased. Corn, sugar cane and vegetable oil can all be used for food or to produce biofuel.
Biomass is the total dry mass of an organism. In other words it is the name given to the material that makes up a living organism, excluding water. Therefore it is the compounds such as proteins, fats, carbohydrates, vitamins etc. Plants produce biomass when they grow. To produce biomass plants need carbon dioxide and water (which they use to make glucose in photosynthesis) but they also need some nitrogen to make proteins, and some phosphorous so they can make DNA. They get these in mineral salt compounds called nitrates and phosphates from the soil. Confusingly biomass is also a term used for biological material that can be processed to make biofuel.
You can produce biofuel from any organic material. Some materials will convert better than others.
Some chemicals make plants grow. They are called fertilizers. Some chemicals plants make plants die. When intentionally applied, they are the type of pesticide called herbicides. Some chemicals do not affect plants.
That would depend on the type of biofuel. Wood is a biofuel, and it can be stored as logs, pellets, or chips, in huge stacks or mounds. (methane)Gas can also be a biofuel, which is stored in some sort of pressurized vessel. Vegetable oils and fats can also be biofuels, and they're stored in tanks.
Biofuels is a substitute for some fossil fuels. Petroleum etc.

There are several products that can be used as biofuel such as cellulose, algal oil, corn, soy, sugar cane, camelina and jatropha, rapeseed, methane, animal fat and paper waste.
It's supposed to be from renewable resources, but as far as sustainability, there is some controversy over that.
Rock salt crystals themselves are not directly used for biofuel production, as they do not contain organic material necessary for generating biofuels. However, salt can be involved in processes related to biofuel production, such as in the purification of certain feedstocks or in specific biochemical reactions. The focus for biofuel production typically lies in organic materials like plant biomass, algae, or waste products that can be converted into energy. Therefore, while rock salt can play a role in some processes, it is not a source of biofuel.
some name of plants in morocco are cork oak, evergreen oak, juniper, cedar, fir, and pine
