Transcript Feeding Relationships and Symbiosis

Feeding Relationships and
Symbiosis
State Standards
• 6th – Life #8 Describe how organisms may
interact with one anther
• 7th - Life #2 - Investigate how organisms or
populations may interact with one another through
symbiotic relationships and how some species
have become so adapted to each other that neither
could survive without the other (e.g. Predatorprey, parasitism, mutualism and commensalisms)
• 7th - Life 8 Investigate the great diversity among
organisms
Learning Objectives
• I will be able to describe and provide
examples of the 3 different types of
symbiosis.
• I will be able to create a food chain and
food web.

Symbiosis
• Symbiosis - is a close
relationship between
two species that
benefits at least one
of the species
• Three Types;
mutualism,
commensalism and
parasitism

• 1. Mutualism • a relationship in
which both species
benefit
• Wrasse Cleaning
• Wrasse & Moray Eel

• 2. Commensalism • One species
benefits and the
other species is
neither helped nor
harmed

Symbiosis
• #3 Parasitism • Involves one
organism living on
or inside another
organism and
harming it

Feeding Relationships
• Predation • An interaction in
which one organism
kills and eats
another
• Killer Whale

• Predator • the organism that
does the killing
• Prey • An organism that is
killed in predation

Food Chains
• Food Chains • The series of events
in which one
organism eats
another

• Food Web • The pattern of
overlapping food
chains in an
ecosystem
