Does movements of energy and nutrients matter through ecosystem different and where do bacteria and fungi get their energy from?
Rk Naresh
Chemical nutrients and energy tend to flow in the same direction for most of an ecosystem, but the main difference is that the nutrient cycle is recycled in the ecosystem while the energy flow is ultimately lost from the ecosystem to the universe at large. Organisms that make their own food are called primary producers and are always at the start of the food chain. Animals and micro-organisms like fungi and bacteria get energy and nutrients by eating other plants, animals and microbes.
