The Chuditch would likely gain the most energy from their food, as they are carnivorous and typically consume other animals which are high in energy content. The producers such as Marri trees and Eucalyptus trees would gain energy through photosynthesis, but they do not consume food like the animals mentioned. Woylies and ring-tailed opossums would also gain energy from their food, but as herbivores/omnivores, their energy content may not be as high as that of a carnivorous animal like the Chuditch.
