Answer:
Trunk-crown
Twig
Crown-Giant
Trunk-Ground
Step-by-step explanation:
The ectomorphs have some morphological similarity irrespective of their evolution in specific habitats. However, most of the ectomorphs have evolved from the four islands – Hispaniola, Cuba, Jamaica, and Puerto. So these ectomorphs have been classified based on habitat and morphology. The phylogeny tree depicts following order of evolution 1) Trunk-crown 2) Twig 3) Crown-Giant and 4) Trunk-Ground
The crown giant has the largest body length and the trunk ground has smallest body length. In terms of habitat, crown giant live in highest part of the trunk while trunk ground lives in the lower trunk and ground.
