The correct option is this: PIONEER ORGANISMS MOVE INTO NEW COMMUNITIES FIRST.
Ecological succession refers to the process of change that occur to the species in a given community over a period of time. Succession is caused by change in the environment and its effects on the living organisms that are living there. There are two basic type of ecological succession, these are primary and secondary ecological succession.
Primary ecological succession typically occur in an environment that is devoid of any form of vegetation or life form; it is usually a bare land that lack soils that are needed for plants' growth. The first set of plant that grow in this kind of environment are called pioneer species. Such plant usually have ability to survive in harsh environment. Example of such plant is ferns. Primary succession is very slow and can take hundreds of years.
Secondary succession usually occur as a result of an event which reduce an established ecosystem into a smaller population. The event could be a forest fire, flooding, etc. Secondary succession takes place in an environment in which some living organisms are still existing. The process is fast compared to primary succession.

A species is an integrated group of populations, integrated through their form, behavior, and preferred living conditions, the consequence of similar DNA and reproductive isolation from other species. A population is several organisms of the same kind in a particular area.
Water molecules would probably be it since they are in water and they are made up of two hydrogen and one oxygen.
