In a seagrass ecosystem, nutrients limit primary production under low nutrient (oligotrophic) condition, while light becomes the limiting factor under high nutrient (eutrophic) condition. Discuss how this happens with respect to the three primary producers (seagrass, macroalgae, phytoplankton) as the condition changes from oligotrophic to eutrophic.

Physical and Chemical features

The physical property of a compound could be determined without modifying the originality of the compound. Examples of physical properties are density, hardness, color, boiling, and melting point. The chemical property expresses the ability of a compound to undergo a particular chemical change.
