Definition
| pyrodinium bahamense...a unicellular photosynthetic dinoflagellate |
|
|
Term
| why does the pyrodinium stay in the bay? |
|
Definition
| as the water comes into the bay, evaporation takes place in the shallow water causing the surface water to sink because the increase in salinity therefore density...the pyrodinium stays near the surface so when the denser water is carried out of the bay the pyrodinium stays. |
|
|
Term
| why is pyrodinium favored in the bay? |
|
Definition
| because mangrove trees are on the shore and their leaves fall...intense bacterial decomposition increases the organic nutrient levels in the water. |
