*** WILL BE GIVING BRAINLIEST *** After a week with lots of rain, runoff has caused a large amount of fertilizer to wash into the ocean from the farms on the California Coast. This caused a bloom in phytoplankton. When these microscopic creatures die after their short life, their decomposition creates an environment in the water with little oxygen, making it toxic to mussels and crabs. Identify two organisms which may benefit from this decline and two organisms (other than mussels and crabs) which may suffer. Explain why this advantage or disadvantage would occur.
