Based on the hispaniolan phylogenetic tree, which of the following is the correct order of appearance of the ecomorphs on that island, from earliest to latest?

1. trunk-crown2. twig3. crown-giant4. trunk-ground

Trunk-crown

Twig

Crown-Giant

Trunk-Ground

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.

"a.) well–developed vascular system."

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
