Review: Classify the organisms according to the kingdom where they belong:
Kingdom Plantae

Objectives:• Describe how living things interact with
each other;• Make a chart that shows the
relationship among living things;• Realize the importance of maintaining
harmonious relationship with each other.

Predation• A stronger organism called the predator eats the weaker
organism called the prey.

Predator Prey

Competition• Some living things have the same need that is
why they used to fight each other.
Intraspecific Competition- involves organisms of the same kind/species.
![Page 14: Interaction of Living Things](https://reader033.fdocuments.net/reader033/viewer/2022061223/54c363d84a79599c178b4569/html5/thumbnails/14.jpg)
Interspecific Competition- involves organisms among different species. (competition in a community)
Lioness and hyenas fighting for food

Cooperation• Some organisms help one another for higher
chance of survival.
Ants are helping one another to protect and sustain their colony.
![Page 16: Interaction of Living Things](https://reader033.fdocuments.net/reader033/viewer/2022061223/54c363d84a79599c178b4569/html5/thumbnails/16.jpg)
Symbiosis• An interaction that involves two
different kinds of organism, where one is benefited while the other may be benefited, harmed or unaffected.• Examples are mutualism, parasitism
and commensalism.

MutualismThe two organisms are benefited.
Butterfly drinks nectar from flowers.Butterfly helps
the flowers in pollination.

Ants protect aphids from predator
Aphids give food to ants.

Parasitism
• One organism is benefited (parasite) , the other is harmed (host).
Man is the host.
Leech is the parasite.
![Page 20: Interaction of Living Things](https://reader033.fdocuments.net/reader033/viewer/2022061223/54c363d84a79599c178b4569/html5/thumbnails/20.jpg)
Parasitism
Ectoparasitism- parasites are found outside the host’s
body
Endoparasitism- parasites are found
inside the host’s body

Commensalism
One organism is benefited (commensal) while the other is not affected (host).
Shark is the host.
Remora is the commensal.

Commensalism
Tree is the host.
Orchid is the commensal.
