BIOLOGY
  • STANDARD 2.0:
    • The student will investigate the interactions of organisms within their environment through different relationships, population dynamics, and patterns of behavior.
  • LEARNING EXPECTATION 2.1:
    • Compare and contrast the different types of symbiotic relationships.
  • PERFORMANCE INDICATOR LEVEL 1:
    • Identify Commensalism, Parasitism, and Mutualism, given a scenario with examples.
  • Link to TN Curriculum Standards
this standard may be difficult to teach because
This Standard May Be Difficult To Teach Because…
  • Mutualism and Commensalism share similar concepts, and can thus be confusing to students.
  • This may be the first time students are exposed to the three distinct groups of symbiotic relationships.

SYMBIOTIC RELATIONSHIPS

  • SYMBIOSIS is the interaction between 2 different organisms living together
    • HOST- usually the LARGER of the 2 organisms
    • SYMBIONT- usually the SMALLER member
the three symbiotic relationships are

parasitism
PARASITISM
  • Is a relationship where the Symbiont lives in/on the Host
  • The Symbiont (or Parasite) BENEFITS
  • The Host is HARMED
  • For example, the tick in the picture above is a parasite. It benefits by extracting blood from its human host. The human is harmed because

EXIT

slide7

Mutualism

  • Is a relationship between the host and a symbiont, where both organisms benefit and neither is harmed.
  • The relationship can be long or short term.
  • For example, in the photo above, the host flower benefits by being pollinated by the traveling butterfly. The symbiont butterfly benefits from the nectar that it extracts from the flower.

EXIT

commensalism
COMMENSALISM
  • Is a relationship between the host and symbiont, where the symbiont benefits and the host is neither helped nor harmed.
  • The symbiont benefits by receiving transportation, housing, and/or nutrition.
  • For example, in the photo above the symbiont barnacles receive transportation from the host whale. The host whale is neither helped nor harmed by the barnacles.

Clownfish are frequently found in the tentacles of sea anemones. Sea anemones capture their prey by paralyzing them with their tentacles. However, the clownfish produces a mucus that prevents the tentacles from harming it. By dwelling amongst the tentacles the clownfish receives a protected home. This relationship is an example of …

Lampreys are primitive fish with limited digestive systems. They attach to and feed on the body fluids of fish with more advanced digestive systems, often leading to the death of the host fish. This relationship is an example of…
