A leaf from a deciduous forest that falls into a large stream and is consumed by insects would be a source of primary energy for the stream ecosystem
Most of the energy that enters an ecosystem comes from solar radiation. The producing organisms that carry out photosynthesis absorb solar energy and fix it in chemical energy. When consumers feed on producers, part of that energy goes to these organisms, which, by serving as food for other living beings, also pass on part of their energy to them. This, therefore, flows, in a unidirectional direction, passing from a lower level to a higher one.
With this information, we can conclude that a leaf from a deciduous forest that falls into a large stream and is consumed by insects would be a source of primary energy for the stream ecosystem
