Scientist describe energy as ability to do or perform work.
Because physics is the most fundamental science. Physics is the study of energy and motion. All other sciences would not exist without a form of energy or motion. Chemistry: Chemical energy Biology: has a lot to do with chemicals Astronomy: Stars are fueled by nuclear energy Geology: Rocks are formed by kinetic and thermal energy Et Cetera
Length is fundamental because space is fundamental and relates two other fundamental units energy and force.
Because it is defined by fundamental SI units, ie the meter and the Newton, which is a force. 1 Joule is the energy used to move 1meter against a force of 1 Newton.
Energy
Science describes more than two fundamental forms of energy, but perhaps you are thinking of kinetic energy and potential energy. Heat is also a form of energy, as are chemical energy, nuclear energy, electromagnetic energy, etc.
The energy conversion system of most components evolved at a very early stage. This is why the fundamental aspects of energy metabolism is said to be similar to other organisms.
