Ecosystems at Risk Ecosystems and their functioning What is an ecosystem? Ecology – the science that examines the interactions between organisms and their living (biotic) and non-living (abiotic) environment. Groups of organisms and their biophysical environment interact and exchange matter and energy. Ecosystem – the dynamic complex of plant‚ animal and micro-organism communities and their non-living environment as a functional unit. Ecosystems are dynamic; constantly changing and adapting

Ecosystems can be complex and hard to manage. In fact‚ they can encompass diverse species and habitats. As such‚ specific planning and prioritization is needed in order to protect them from the different threats that might undermine their existence‚ but also preserve and enhance the life of species through a variety of measures and activities. Description of ecosystems The Shut-in Mountain is home to a variety of specifies. Among‚ these species we find invertebrates‚ fish‚ birds‚ fen‚ etc. The
