Viewing the undersea world from a land-based perspective, it is easy to consider a colony of coral to be something similar to a bed of flowers: Many species of both display brilliant markings and have intricate, visually appealing shapes. Yet, their relationship is predominantly aesthetic, as the basic composition of a coral polyp, an animal, differs markedly from that of a self-photosynthesizing plant like a rose or zinnia.
It could even be argued that lichen, a fungus, bears more in common with corals than flowers do, since both lichen and corals are typified by mutually beneficial relationships with photosynthesizing algae. While there are some species of coral that can exist solely by capturing food, most coral receive energy by hosting millions of single-celled organisms known as zooxanthellae. The zooxanthellae are provided safety from predation as well as certain by-products of the coral’s metabolism, such as ammonia, which zooxanthellae require to grow and reproduce. In return, the coral uses a portion of the energy zooxanthellae produce through photosynthesis for its own sustenance, growth, and reproduction.

Official Explanation
1. The author compares coral to a bed of flowers to illustrate
Difficulty Level: Hard
Explanation
In the first paragraph, the author points out how a land-based perspective can lead to the wrong conclusion about corals—stated more generally, how people’s perceptions of other habitats (the ocean) are influenced by their own environment (the land). Choice (A) expresses this broad point of the paragraph.
The correct answer is (A).
