Algal bloom is defined as the rapid growth of algae in freshwater or marine water. Algal bloom is green or yellowish in color that cover the top layer of water systems.
Algal bloom in the given case is caused by the excess of nutrients that is nitrates from fertilizers into waters and higher concentrations of nitrates causes uncontrollable growth of algae.

Answer:
Nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli.
Explanation:
The air travels through the respiratory system during inhalation in the next order:
- <em><u>Nasal cavity:</u></em> You inhale air into your nose.
- <u><em>Larynx:</em></u> The air travels down to this organ, a hollow, tubular structure that plays a key role in phonation, respiration, and deglutition.
- <u><em>Trachea:</em></u> (Or <em>windpipe</em>) is a wide, hollow and cartilaginous tube that connects the larynx to the bronchi.
- <em><u>Bronchi:</u></em> The trachea divides into two primary bronchi; they are the main passageway into the lungs.
- <em><u>Bronchioles: </u></em>The bronchi develop smaller the closer they get to the lung tissue and are then consider bronchioles.
- <em><u>Alveoli:</u></em> They are tiny air sacs located at the end of the bronchioles, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
