A symbiotic relationship in which one member is benefited and the second is neither harmed nor benefited. highered.mcgraw-hill.com/sites/0070294267/student_view0/glossary_a-d.html

A form of symbiosis in which only one of the animals benefits from the relationship. www.reefed.edu.au/glossary/c.html

One organism benefits while the other is neither harmed nor benefits. Example: Moss growing on trees benefits by being raised above the forest floor competition, while the tree doesn't get anything out of the deal either way. www.nps.gov/olym/edgloss.htm

The interaction of two or more dissimilar organisms where the association is advantageous to one without

Definitions of Amensalism on the Web:

An inter-organism interaction in which one organism negatively impacts another organism without receiving any direct benefit itself. www.sustainableag.net/glossary_a-d.htm

A type of symbiotic relationship in which one of the partners in the interaction is inhibited and the other is unaffected. www.pestmanagement.co.uk/lib/glossary/glossary_a.shtml

Amensalism is an interaction between two species where one impedes or restricts the success of the other while not being affected, positively or negatively, by the presence of the other. Usually this occurs when one organism exudes as part of its normal metabolism a chemical compound detrimental to another organism. en.wikipedia.org/wiki/Amensalism

Slide 42

Definitions of Filter feeding on the Web:

Straining food particles from water that is pumped through or over a gill surface. www.seagrant.wisc.edu/outreach/nis/Attack_Pack/Fact%20Sheets/terms.htm

feeding by taking sea water into the mouth then forcing it out through the matted, sieve-like bristles of the baleen plates. Food suspended in the water, such as small schooling fish and plankton, is trapped inside the mouth cavity as the water exists. gmbis.marinebiodiversity.ca/BayOfFundy/glossE-H.html

filtering suspended food particles from water current by means of the gill rakers www.deh.gov.au/coasts/species/marine-fish/glossary.html

Obtaining food by passing water through a filtering mechanism. www.50ftdredge.com/EIS/EIS_19.1.html

Filter feeders (also known as suspension feeders) are animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialized structure, such as the baleen of baleen whales. en.wikipedia.org/wiki/Filter_feeding
