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.

Answer:
A blue room
Explanation:
Green light is the least effective for plants because they are themselves green due to the pigment Chlorophyll.. Blue light helps encourage vegetative leaf growth, and red light encourages flowers. this happens because the amount of blue, red and far red spectrum of light that reaches the planet changes with the seasons. As days start to get longer, more blue spectrum light reaches the surface of the earth. This initiates a vegetative growing stage for most plants leading into the spring and early summer. As the days start to grow shorter, and more of the red and far red spectrum reaches the surface, it leads into the late summer and fall reproductive season.
