Deforming Frogs

This is a summary of the article Deformed Frogs written by Alice, Chris, Elena, and Amanda of 7F.

Deformed frogs are increasing because of algae growth from the run-off of nutrients from nitrogen and phosphorus from the land. The snails eat the algae and breed more, the snails are a home for the parasites and so when there are more snails the parasites use it as a breeding space so they will spread faster. Snails excrete infectious parasites into the water thus infecting tadpoles. Therefore, many more frogs will become deformed. Deformed frogs have loss of limbs, or extra limbs. Birds will then eat the frogs with parasites, and then the parasites will be excreted out into ponds and breed again in the growing snail population. The enviornment that these frogs can be found is just a normal pond. To help the study of deformed frogs, a research group made 36 artificial ponds with snails, some ponds had a run-off to test.
