In not more than 200 words or 5 sentences, answer or explain the following situation. In a seagrass ecosystem, nutrients restrict primary production under low nutrient (oligotrophic) conditions, while light becomes the limiting factor under high nutrient (eutrophic) conditions. Discuss how this happens with respect to the three primary producers (seagrass, macroalgae, phytoplankton) as the condition changes from oligotrophic to eutrophic.
Algae scraped: 0.962 m? Use mathematical and computational thinking to extrapolate your measurements obtained from the grid area to the entire pool to determine the total algal biomass in this pool. Assume the area covered by algae is equivalent to 30% of the pool's surface area. Extrapolate the total algal biomass present in the pool from your data. Algal biomass collected: 0.202 g Area scraped: 0.962 m2 Pool surface area: 28 m2 Pool's estimated total algal biomass: Enter value. g Hìnt
