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

2013 Aquatic Ecosystem Function An ecosystem can be defined as “all the organisms in a given area as well as the abiotic factors with which they interact” (Reece et al. 2010). Common aquatic ecosystems range from the largest oceans to the smallest creeks‚ but each aquatic ecosystem plays a pivotal role in global ecology. Each ecosystem consists of important aspects including nutrients cycling‚ biodiversity‚ and energy flow that contribute to the overall state of the ecosystem. However‚ the limited

An explanation of the key abiotic components of the ecosystem? That are non-living chemical and physical factors in the environment‚ which affect ecosystems. A good example is that a lot of small bushes and shrubs would not be able to live here because all the really tall trees would block most of the sunlight causing a lack

In this lab several molecules were created and given specific bond lengths before running a Gaussian test for optimization and frequency. Through this test the vibrational frequency‚ force constant‚ reduced mass and point group were

Wetlands consist primarily of hydric soil‚ which supports aquatic plants.[3][4] The water found in wetlands can be saltwater‚ freshwater‚ or brackish.[4] Main wetland types include swamps‚ marshes‚ bogs and fens.[5] Sub-types include mangrove
