No, it is a highly specialised scientific term. In everyday contexts, 'warm-blooded' is the appropriate phrase.

Typically no. Homothermy is a characteristic of certain animals (mammals, birds, some fish). Some plants can generate heat (thermogenic plants), but they are not classified as homotherms.
