<strong>Biogeochemical</strong> Cycling in Ecosystems • An ecosystem is a community of different species and their non-living environment in which energy flows and chemicals cycle. • Chemical cycling in an ecosystem begin w/ inputs from outside. – Rain – Dust – Volcanic ash
<strong>Biogeochemical</strong> Cycling in Ecosystems • Chemicals cycle internally within ecosystem through – Air, water, rocks, soil and food chains – By way of physical transport and chemical reactions • Ecosystem can lose chemical elements to other ecosystems – E.g. river transport from land to sea
