OBJECTIVE
Describe the effects of interactions among organism in their environment
beneficial and harmful interactions occur among living things and their
environment as they obtain basic needs
Demonstrate understanding of the effects of interaction between and among
living things

 REVIEW
Have a review on the type of interaction of organism
Direction: Arrange the jumbled letters to get the correct
answer for each question.
1. It is the type of interaction where both species
benefit from the relationship.
UMTULISMA
Mutualism
2. It is type of interaction where one organism
benefits while the other one is not harmed nor
affected.
C ON E M S A M L I S M
3. It is an interaction where the one organism is
benefits and the other one is harmed or badly
affected
RETIPDAON
4. It is an interaction where the organism that
benefit is called parasite and the one that is
harmed is called the host.
ARPASISMIT
5. It is striving between organisms for the things
needed for survival

MOTIVATION
Show a picture of farm
What do you see in the picture?
What living things are found in the picture?
What is given off by the tree that is needed by the
cow?
What is given off by the cow that is needed by the
tree?
What do you think will happen the cow or other
animals will not give off carbon dioxide?
A farm
Cow, trees
Oxygen
Carbon dioxide
Plants will not have
carbon dioxide they
need
There will be less
oxygen in the
environment
What do you think will happen if trees or other
plants are not present in the environment?
Yes, they maintain
Aside from cow, what other animals you can find in the balance of
oxygen and carbon

environment?
This time, we will learn more about the interaction of
organisms by performing an activity.
EXPLORE
Group Activity
 Setting of Standards
 Group pupils into two
 Let each group perform the activity
Group I
Direction: Complete the table below. Identify what type
of interaction being shown in the pictures. Describe the
effect of interactions between the organisms
Group 2
Directions: The following pictures either show
beneficial or harmful interactions in the
environment. Read the information in each
picture and answer the questions that follow.
Standards of Group
Activity:
 Stay in your group.
 Observe social
distancing
 Don’t take off your
mask
 Use soft voices
 Prepare your
outputs in 5
minutes
Guide Questions:
1. In pictures 1 to 5, which organism is benefited and
harmed?
2. Describe the interaction between organisms in pictures 1
to 5.
3. What pictures show beneficial interactions in the
environment?
4. What pictures show harmful interactions in the
environment?
5. What made the interactions beneficial? harmful?
6. If you are going to choose from the different interactions
you’ve seen in the pictures, what do you think is the best?
Why?
GROUP 3
Direction: Draw an interaction of organisms found in
the environment. Answer the following questions
1. Identify and describe the interactions of organisms in
found in the environment.
2. Are the interactions you identified and described
important? Why?
3. Which interactions are beneficial? harmful?
4. How do predator-prey relationships help to maintain
a balanced ecosystem?
EXPLAIN
Group Reporting
 Allot time to the pupils to present their output
 Give feedback.
 Discuss the answers and give additional input.
How do you find the activity?
Based on your activity, what are the effects of
interaction of organisms?
Which interactions show beneficial effect?
What are some beneficial effects?
Fun, interesting,
easy
Harmful and
beneficial
Production of fruits ,
beautiful plants, etc
Decrease of the
community of
animals and plants
What are some harmful effects?
(Using PowerPoint Presentation, the teacher tells
additional background about the interaction of
organisms in their environment)
Values integration: It is time to give back to the
environment that supports our living. Which activities
can be done to show love and care for our environment?
ELABORATION
A. Generalization
What are the different interactions of living things in the
environment?
How do you describe the effects of these interactions
among organisms in their environment?
b. Application
Describe at least three interactions that you see in the
picture of environment below. Answer the questions that
(stop cutting down
trees
plant a tree, don’t
pick flowers, etc.)
Mutualism,
commensalism,
predation, parasitism
and competition
They have beneficial
and harmful effects
on the ecosystem.
follow. Do this in your notebook.
1. Are the interactions you identified and described
important? Why?
2. Which interactions are beneficial? harmful?
3. What should you do in order for these interactions
among living things to continue, especially the beneficial
ones?
EVALUATION
Directions: Copy and complete the table below.
Think of five pairs of organisms. Identify
whether their interaction is beneficial or
harmful by checking the proper column.
