Document Summary
A single introduced species can have dramatic effects on both the biotic and abiotic. Are major life zones characterized by vegetation type (terrestrial biomes) or. Consists of all the organisms living in an area, as well as the abiotic factors physical environment (aquatic biomes) with which they interact components of an ecosystem. Ecosystems can range from a microcosm (ex. The space under a fallen log) to a large area (ex. Depends on how the scientist studying it defines the area. Regardless of an ecosystem"s size, its dynamics involve two main processes: energy flow and chemical cycling. Physical laws govern energy flow and chemical cycling in ecosystems. Ecologists study the transformation of energy and matter in an ecosystem and map the movements of chemical elements. Laws of physics and chemistry apply to ecosystems. 1st law of thermodynamics - energy cannot be created or destroyed, only transferred or transformed.
