analyze the flow of matter and energy through trophic levels using various...

TermDefinition
Flow of matter Matter enters an ecosystem at any level and leaves at any level. Matter cycles freely between trophic levels and between the ecosystem and the physical environment.
Flow of energy moves through the community of an ecosystem in a single direction by means of a food chain (web) in which there are the eaters, the eaten, and a combination of both.
Trophic levels The position of a species or a group of species within a food chain or food web.
Food chains simplified model that shows a single path for energy flow through an ecosystem.
Food webs model that shows many interconnected food chains and path ways in which energy and matter flow through an ecosystem.
Ecological pyramids is a graphical representation designed to show the biomass or bio productivity at each trophic level in a given ecosystem. Biomass is the amount of living or organic matter present in an organism.
Marine ecosystem ecosystems which include oceans, salt marsh and intertidal ecology, estuaries and lagoons, mangroves and coral reefs, the deep sea and the sea floor.
Ecosystem biological community and all the nonliving factors that affect it.
Heat a nonmechanical energy transfer with reference to a temperature difference between a system and its surroundings or between two parts of the same system.
Terrestrial Living or growing on land or on or in the ground; not aquatic, arboreal, or epiphytic
Producer is an organism, either a green plant or bacterium, which is part of the first level of a food chain.
Decomposer An organism, often a bacterium or fungus, that feeds on and breaks down dead plant or animal matter, thus making organic nutrients available to the ecosystem.
Omnivore is an animal that eats both plants and animals for their main food
Predator wild animals that hunt, or prey on, other animals.
Energy pyramid is a graphical model of energy flow in a community. The different levels represent different groups of organisms that might compose a food chain.
