Bunnies are made up of cells
Bunnies use energy to carry out their functions
Bunnies grow and change during their life cycle
Living organisms are characterised by various features, including the fact that they are made up of cells, that they need energy to perform their tasks, and that they grow and evolve during their life cycle. Bunnies are living beings since they have all of these features. Option 2 is less correct since, although cells in a rabbit are specialized, this is not a necessity for an organism to be regarded as alive.
