  • Ecology/Energy in ecosystems - Wikibooks, open books for

    Energy is the ability to do work Life manifests itself in energy changes, subject to the laws of thermodynamics Ecosystems exist and operate by virtue of a flow of energy through the components of the system and thermodynamics (the movement of energy) forms the very basis of the biosphere organizing principles introduced in Chapter 2Before proceeding into the relationship between ecology.

  • Sedimentary structures - Wikipedia

    Flow regimes in single-direction (typically fluvial) flow, which at varying speeds and velocities produce different structures, are called bedforms In the lower flow regime, the natural progression is from a flat bed, to some sediment movement (saltation etc), to ripples, to slightly larger dun Dunes have a vortex in the lee side of the dune.
