But what does that dependence look like? Each organism living in an ecosystem plays an important role in the flow of energy within the food web. The role of a bird is very different from that of a ...

Photosynthesis is the dominant source of energy in most ecosystems through conversion of light to C-H bonds in organic material, and so the flow and fate or carbon is tightly linked to energy flow.

the researchers assembled trophic network models of the grassland ecosystem. These contain the standing biomass on every feeding level and the flow of energy through feeding interactions between ...

Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure, and understanding the ...

So how can scientists recreate an extinct ecosystem? Acknowledging these ... It is a starting point to develop energy flow models.” “This trophic food web is quantitatively reconstructed ...

they exchange energy, momentum and enstrophy, a measure of the strength of the swirling motion in fluids. In order to better ...

The study is published in Nature Climate Change as "Using ecosystem experiments to improve vegetation models." The ORNL research was supported by the Department of Energy's Office of Science ...
