Natural wetlands are lands which, due to geological or ecological factors, have a natural supply of watereither from tidal flows, flooding rivers, connections with groundwater, or because they are perched above aquifers or potholes.
Realize that many verbs can be both transitive and intransitive. An action verb with a direct object is transitive while an action verb with no direct object is intransitive. Some verbs, such as arrive, go, lie, sneeze, sit, and die, are always intransitive; it is impossible for a direct object to follow.
Verbs and objectsSome verbs (often called transitive verbs) need an object to complete their meaning. Some verbs (often called intransitive verbs) do not take an object. Some verbs need both a direct object and an indirect object. Some verbs can take a wh-clause or a that-clause as an object.
