energy to do work
No, not all machines require the use of simple machines. Some machines rely on more complex mechanisms or technologies to function efficiently. Simple machines are often used to make work easier by multiplying or redirecting force, but they are not a requirement for all machines.
All machines are constructed from six simple machines
All you have to do is fine a simple task to do and find simple machines and connect them together to make it. All you have to do is fine a simple task to do and find simple machines and connect them together to make it.
All simple machines change the direction or magnitude of a force to make work easier. They operate on a basic mechanical principle and do not have moving parts. Simple machines can be combined to create more complex machines.

Simple machines are any device used to change the direction and or magnitude of a force. Levers, pulleys, wheels, and the inclined plane are all examples of simple machines.
A bicycle consist of several simple machines, which makes it a complex machine.
Technically, no animal is a simple machine. Simple machines are the basic elements which comprise all other machines. Though some people compare animals to machines and comparisons between anatomy and simple machines might be possible, they are far from obvious.
