Answer:
The node therefore represents the end of the ancestral taxon and the stems , the species that split from the ancestor. The two taxa that split from the node are called sister taxa.
Explanation:
The preferred prey item would be frogs.
What is optimal foraging theory?
It is a theory in ecology that proposes that predating animals that get the most energy from minimal efforts are favored by natural selection.
In order words, selection forces prefer investing minimum energy in order to extract maximally available energy.
In this case, the heron needs to use the lowest time to harvest the maximum energy possible. Since all the preys offer the same amount of energy, the one that requires the lowest time would be preferable for the heron.
In other words, frogs would be the most preferable prey.

Answer:
Without the model, we can't help you. But a healthy coral reef would most likely have some kind of productive ecosystem.
Explanation:
I would assume the the diagram includes a reference to fish, algae or other plant-like life, and the coral itself. The coral polyps are in a symbiotic relationship with algae; the algae provide the polyps with energy via photosynthesis and the polyps build "homes" for the algae and other species living in the reef (the "home" for algae is literally the coral reef).
Other species like animal life use the reef as a place of protection against larger predators. Fish frequent reefs since many types of aquatic predators dislike shallow waters and coral reefs provide plenty of nooks and crannies to hide inside.
