The levels of organisation are

Domain: Eukarya

Kingdom Animalia

Phylum :Chordata

Explanation:

They all share these levels of organisation because;

for the Domain Eukarya, they have;

→multi-cellular cells containing nucleus; and other membrane bound organelle.e.g Mitochondrial.

→their DNA located in the nucleus packaged as linear chromosomes bounded by histone proteins.

→mode of reproduction which is sexual.

They share Kingdom Animalia because;

→they have multi-cellular, specialised cells, bounded by plasma membranes.

→they have specialized tissues, organs, and system.

→they all undergo heterotrophic mode of nutrition as evident in the question 'that they must consume plants and animals as source of energy'

→they exchanged communication by nervous ssytem and 

→ use homeostatic mechanisms to regulate water balance of the body through the kidney.

→Humans,Rabbits,and whales are VIVIPAROUS; they give birth to young ones alive.

→Most fishes lay eggs to reproduce, they are said to be Ovoviviparous.

They belong to phylum Chordata because ;

→they all have noto chord; which serve as template for axial skeleton.

dorsal hollow nerve cord -template for the brain and spinal cord

→pharyngeal slits- templates for gill aches in bony fishes and components of inner ear in land animals.

→ tail length varies in these organisms.
