The document outlines a lesson plan about interactions in a community. It discusses five types of symbiotic relationships: mutualism, commensalism, parasitism, predation, and competition. Students will work in groups to identify examples of these relationships and present their findings. They will then take a short quiz to test their understanding of the different interaction types. For homework, students must provide one example each of the five relationships in drawing form.

1. Analysis
 What have youlearnedfromgroup1?
 Verygood! Because theybenefitfromeach
other,howdo we call this?
 Verygood!
 Mutualismisa relationshipinwhichtwo
organismslive togetheranddependoneach
other.
 What have youlearnedfromgroup2?
 Verygood!
 We call theirrelationshipascommensalism.
Commensalismisasymbioticrelationshipin
whichone organismbenefitswhile otheris
not affected.
 What have youlearnedfromgroup3?
 Verygood! Whenone organismbenefits
and the otheris harmed,we call this
relationshipasparasitism.
 In thiskindof relationship,whatdowe call
to the one who benefits?
 In thiskindof relationship,whatdowe call
to the one who isharmed?
 What have youlearnedfromgroup4?
 Correct! An animal that kills and eats
another animal is called predator. The
smallerandweakeranimal thatthe predator
kills and eats is called the prey. We call this
relationship as predation.
GROUP 5
DIRECTIONS:Formthe givenpuzzle.Tell
somethingaboutthe relationshipof two
speciesinclass.
 Both the flowerandthe butterflybenefit
fromeach other.
 We call it as mutualism.
 The small fishbenefitsfromthe shark.
 He usesthe sharkfor transportationand
to avoidpredators.
 The sharkwas not harmedor helpedby
the small fish.
 The mosquitobenefitsfromthe human
 The human isharmedby the mosquito.
 We call thisas a parasite.
 We call thisas the host.
 The lioneatsthe weakanimal.
 The lionisa predator.
 The lionisconsideredstronger.

4.  What have youlearnedfromgroup5?
 Verygood! That relationship iscalled
competition. Animalsinanecosystemuse
space,waterand foodas theyincrease in
size. Competitionisthe struggle among
organismsforthe same materialsor
conditions.
 Those five relationshipsare calledsymbiosis.
 What do you think the meaning of
symbiosis?
 Very good! Symbiosis is the interaction
between the two species.
2. Generalization

discussion?
 Verygood!So whatare those five symbiotic
relationshipsthatwe justlearned?
3. Application
