-all species change gradually over time.
Explanation:
Mutation often results from cell replication and division. These occur as small, random, errors within the genetic code that become more common or stable within a population over time as traits.
As organisms live within varying niches, environmental changes may render some genetic traits obsolete. However, others may become more beneficial as an adaptation. These adaptations, which make an organism and its offspring suited to a niche, and more likely to survive and reproduce become inherited- this process is called evolution.
Salt marshes are affected by numerous things but the primary influence is "Tidal Flow".
