Question

Chytrid fungus is a pathogen that infects proteins in amphibians such as those found on the mouthparts of tadpoles and the skin of adult frogs. The fungus has been detected in over 100 amphibian species and is associated with rapid population declines or extinction of frogs in several areas around the world.
Which argument explains how the spread of chytrid fungus can harm freshwater ecosystems?

Answer 1

This might be too late to be helpful, but I think the answer choice that describes the most harm is the one about how the fungus infecting tadpoles could affect underwater plant life. Plants are a fundamental part of the ecosystem, and damage to the plant population would have negative effects for all other organisms too
