Answer:

the death of tadpoles is often related to a lack of oxygen in the water, usually caused by a sudden algal bloom. If there has been some warm weather and the water has turned green, this indicates that there is a lot of algae growing in the water. Algae removes oxygen, leaving the water ‘anoxic’, and the tadpoles suffocate.
