“Living Together”

Types of SymbiosisTypes of Symbiosis• Mutualism

– Both the symbiont and host benefit.

• Commensalism– The symbiont benefits with little

effect on the host.

• Parasitism– The symbiont benefits to the

detriment of the host.

• Mutualism– Both the symbiont and host

benefit.

• Commensalism– The symbiont benefits with little

effect on the host.

• Parasitism– The symbiont benefits to the

detriment of the host.

• Aegism– An association for protection

• Inquilism– One organism shelters within another

organisms

• Endoecism– One org shelters in the burrow or defensive

shelter of another

• Phoresis– One org uses another for transportation

• Epizoism- A sessile org lives on top of another

Obligate Versus Facultative

Relationships

Obligate Versus Facultative

Relationships

Obligate Relationship:Relationship is necessary for organism to surviveEx. coral and zooxanthellae

Facultative Relationship:Can survive without symbiont, but not as wellEx. anemone fish and anemone

MutualismMutualism

zooxanthellae and coralszooxanthellae and corals

Zooxanthellae give corals:• Increase coral growth by enhancing

calcification process• Provide energy• Give oxygen

Coral give zooxanthellae:• Nitrogen waste• A place to live• Carbon dioxide waste• Protection through their hard skeletons and

stinging cells• Harmful UV light is filtered by coral

Inquiry

1. Define mutualism, commensalism, and parasitism.

2. Provide examples of each.3. What are the benefits the

zooxanthellae and coral receive?
