what is plankton and write harmful effect of algal bloom
Answers
The small and microscopic organisms drifting or floating in the sea or fresh water, consisting chiefly of diatoms, protozoans, small crustaceans, and the eggs and larval stages of larger animals are known as planktons.
The presence of algal blooms can induce a variety of damaging effects on the surrounding environment and its inhabitants. Toxins released from the algal bloom can cause anything from tissue deterioration and illness, to death and extirpation. How these toxins induce their effects on their victims vary by mechanism, but can include malnutrition, reduced appetite, suffocation, and respiratory failure. The results are devastating—not just for the resident aquatic populations, but also to many other plants and animals in the community, including people. In humans, direct exposure to toxins via drinking water can cause a series of health issues, such as rashes, stomach or liver illnesses, respiratory problems, and neurological effects.

Have a nice day :D
plankton is a very very small fish that is a common prey to almost all aquatic life..from crabs to whales.
Harmful algal blooms can:
- Produce extremely dangerous toxins that can sicken or kill people and animals
- Create dead zones in the water
- Raise treatment costs for drinking water
- Hurt industries that depend on clean water
hope this helps
