the question doesn't make sense
Law of conversation of energy is when something cannot be created or destroyed. When plants takes water, it changes into sugar.

The law of mass conservation remain valid.
A plant must overcome the law of gravity to grow vertically against it. It must also adhere to laws of photosynthesis to produce energy and grow. Additionally, plants must contend with competition from neighboring plants for resources like sunlight, water, and nutrients.
Because of transitional losses. If you grow plants to feed to animals in order to eat the animals later, not all of the nutrients in the plants becomes nutrients in the meat. Quite a lot is lost in the process. So if humans eat plants directly, you've cut out a huge chunk of losses and made the process a lot more efficient. The same goes for water. It takes a lot more water if you're going to first grow the crops, then raise the cattle, and then eat the meat. Remove the cattle from the chain and you need a lot less water as well.
Yes. With absolutely no law breaking, their employment would become unneccesary. Perhaps you are unaware of the incidence of 'unreported crime'. For example, this could becrimes committed against other criminals who would rather take care of their own business rather than involve the police.
Power plants are not 100 percent efficient due to inherent energy losses during the conversion processes. For example, in thermal power plants, a significant amount of energy is lost as heat during fuel combustion and in the cooling systems. Additionally, mechanical and electrical losses occur in generators and transmission lines. These inefficiencies are a result of the laws of thermodynamics, particularly the second law, which states that some energy will always be lost as waste heat in energy transformations.
There is no law which consists of water.
In water, there is always 8 times the mass of oxygen than there is of hydrogen.
reform of the law, greater participation by the people, more efficient civil administration
Native plants might get extict, because introduce species shall get all the nutrients and water. They do not want the area to change. They want the area to be the same.
They can be saved by putting them under protection or making a law saying you can't hunt that animal or for plants make a law that you can't rip the plants out of the ground or destroy them.
