Algal
Bloom ExampleAlgal
blooms can have varying effects on the marine ecosystem.
Some can be beneficial,
feeding fish and supporting the ecosystem as the first link in the food chain.
Other times Algal blooms can be harmful. This happens when they are too large
or last too long. Blooms become ecologically harmful by using up all the nutrients,
and oxygen in the water. Algal blooms can also block sunlight and absorb nutrients
needed by other organisms, like kelp.
