Heat from the sun moves through space by the process called <span>electromagnetic radiation. 
H</span>eat moves<span> in three different ways. They are radiation, conduction, and convection. Radiation happens when </span>heat moves<span> as energy waves, which are called infrared waves, directly from its source to something else. This is how the </span>heat from the Sun<span> gets to Earth.

It is very easy and simple difference that is antigens and antibodies .
it can be different due to donor and recipient also .
A type blood having antigens 
whereas B type blood having nil.
B type blood having antibodies
whereas A type blood having nil.
        
             
        
        
        
B. Consumers depend on producers to make food using sunlight. This is the right option.
