4. Interactions among Living Things
in the Environment
Mutualism
It is an interaction of two
organisms wherein both are
getting benefits from each
other
5. Interactions among Living Things
in the Environment
an interaction between organisms in which one is
benefiting while the one never been affected neither
beneficially nor harmfully
Commensalis

6. Interactions among Living Things
in the Environment
Predation
It may be harmful when not in proper control.
In predation, the predator is an animal that is
usually benefited by eating the prey (animal
that is harmed). The number of predator is
determined by the available prey in the area.
7. Interactions among Living Things
in the Environment
Parasitism
Parasites are the small organisms that
live outside or inside the body of the
host (organism that is harmed).
8. An organism cannot exist when
they are living alone. An ecosystem
should be composed of different
organisms for it to survive.
15. Hello
Predation is important as it helps other
organisms to adapt in the environment,
preventing itself to be eaten by other
animals for their survival.
16. Effects of Interaction Among the
Organism
Short-term Long-term
• Predation
- range from mutualism which is
beneficial to both partners or could
be a competition which is harmful
to both partners. The organisms
are called Symbionts in a symbiotic
relationship
• Pollination • Symbiosis
17. Symbiotic Relationship
A relationship that exist in any type of a close and long-term
biological interaction between two different biological
organisms. Mutualistic, commensalistic, or parasitic.
One species benefits while the other species is not
affected. One species typically uses the other for a
purpose other than food.
18. The biological interactions are
important in nature and in keeping
the balance of nature. It maintains
the food web.

21. The food web shows the food
relationship among living organisms
and most food webs start with green
plants. If biological interaction doesn’t
exist, many animals
would die from starvation as the
food web doesn’t exist.
