This Statement is True. The Energy Transfer is always in One Direction(i.e.), from Producers to Herbivores and from Herbivores to Carnivores (or) Primary Trophic Level to Secondary Trophic Level and from Secondary Trophic Level to Teritiary Trophic Level.

✿ iv. In Aquatic Food Chains, Phytoplanktons act as Producers

This Statement is True. Like Plants and Trees in a Terrestrial Ecosystem, Phytoplanktons serve as Producers in an Aquatic Ecosystem.
