Question

read the passage. then answer the question below.
a coral reef in hawaii has hundreds of fish species. many of the fish are active during the day. for example, species such as convict tangs and stareye parrotfish swim in schools as they feed on seaweed that grows on the reef. at night, other fish species, such as snowflake moray eels, come out to hunt.
when they are not active, some fish take shelter among the many species of coral on the reef. other fish hide in the sand and rocks that cover the seafloor.
which of the following best describes a community on a coral reef in hawaii?
the sand, the rocks, and the coral
a school of convict tangs
the snowflake moray eels and the stareye parrotfish

Explanation:

A community in an ecological context includes all the populations of different species in a particular area. The first option includes non - living elements (sand, rocks) which are part of the abiotic environment, not the community (the community is biotic). The second option is just one species (a school of convict tangs is a population of one species). The third option includes two different species (snowflake moray eels and stareye parrotfish), which is a better representation of a community (a group of different species in the same area).

Answer:

the snowflake moray eels and the stareye parrotfish
