Georgia's overall coastal habitats were rated and the results can be seen in the bar graph. The coastal habitats by in large were rated as "fair". One important indicator in the graph is the chlorophyll a category. Explain how the ratings for chlorophyll a might influence the overall ratings of coastal habitats. A) The algae that contains chlorophyll a can be detrimental to other life forms. As algae increase the total organic carbon increases. B) The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develop, C) Chlorophyll, a plant pigment, is measured to indicate the amount of algae in the water. The more chlorophyll a present, the more plant growth and the healthier the aquatic environment. D) There is a direct correlation between algae present and benthic organisms. The more algae, the more benthic invertebrates. That means more abundant food for other animals in the coastal habitats.

The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develops. periodt pooh

Answer:

The answer is: B) The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develop.

Explanation:

"Eutrophication" is the enrichment of surface waters with nutrients for plants, both nitrogen and phosphorus contribute to eutrophication.

A lake with total concentrations of phosphorus and chlorophyll-a of 10 and 2.5 mg / m3 respectively, can be classified into different eutrophication classes.

The symptoms and effects of eutrophication are as follows:

· Increased production and biomass of phytoplankton, associated algae and macrophytes.

· Production of toxins by certain algae.

· Deoxygenation of water, especially at the end of algal growth situations.

The answer is: B) The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develop.
