2. III. Procedure:
Teacher’s activity Students’ activity
A. Preliminary activity
1. Prayer
Good morning class. (Call random student)
Please lead the prayer.
Before you sit kindly pick up the pieces of
paper, align your chairs and keep your
gadgets. Thank you!
2. Checking of attendance
Let me start your attendance. Please raise
your hand and say present if your name is
called.
3. Review
Now let’s have a short recap about our
previews lesson. Will someone tell
something about our topic last meeting?
What is Ecosystem?
Now, we are going to learn all about the
food chain and food web.
B. Literary Integration
Okay, class I have here list of words which
You will determine in our discussion.
Producers-
Consumers-
Good morning, ma’am
(Pick up the pieces of paper, arranged the
chairs and sit)
(Raise hand and says “present”)
Our topic last meeting was all about
Ecosystem.
I learned that ecosystem s made up of all of
the living and nonliving things in an area.
This includes all of the plants, animals, and
other living things that make up the
communities of life in an area. An
ecosystem also includes nonliving
materials—for example, water, rocks, soil,
and sand.
- Plants are called producers because they
make their own food.
-Animals that eat plants are called primary
consumers.
-The primary consumers may be eaten by
other animals called secondary consumers
or predators.

3. Decomposer-
Carnivores-
Herbivores-
C. Discussion
1. Motivation
We are going to have an activity; some of
you are on the hot seat. I want you to check
under your chairs and see if you’re one of
the characters in the story. I have a story
book here and I’m going to read some
characters. I want all characters to come in
front and act when they will hear their part.
Once a upon a time in remote areas of
Cordillera lies a very beautiful garden it has
different species of plants. The plants are
dancing in harmony due to their happiness
that Mr. Sun is shining and dancing too. But
little did the plants know caterpillars are
starting to eat them. While the caterpillars
are eating the plants, suddenly a big frog
jumped into the garden and saw the
caterpillars. The frog immediately let its
sticky tongue out and ate the caterpillars. At
the river side the frog is jumping into
happiness because it ate something for lunch
and the frog suddenly stopped and just
stared on the shining sun. The frog was pre-
occupied due to its happiness it didn’t notice
that a snake was observing and following
the frog. With no hesitations the snake
started devouring the frog. The frog can’t
defend itself because it knows that it is its
fate. To be eaten by a snake. While the
-When all living things die, they become
the food of organisms called decomposer.
-The decomposer breaks down dead
remains and waste materials, and recycle
their nutrients. Earthworm, fungi, and
bacteria are all decomposers.
-An animal that only eats meat
An animal that only eats plant
(The students will look under their chair to
see if they are one of the characters in the
story)
The students who are on the hot seat with a
character of Plants must go in front and
execute their roles in the story dancing in
harmony.
The students who are on the hot seat with a
character of Mr. Sun must go in front and
execute their roles in the story shining and
dancing.
The students who are on the hot seat with a
character of caterpillars must go in front
and execute their roles in the story eating
the plants

4. snake is on its way to its shelter a flying
eagle spotted it and immediately use its
claws to get the snake to its nest and started
eating it. After a day, a young brave hunter
is looking for something to eat and saw the
eagle on its nest and suddenly use its
weapon to catch the eagle. Finally, the
eagles fell to its nest and the hunter is happy
carrying the eagle on its back. THE END
What can you say about the story?
Today we are going to learn how organisms
eat each other and gain energy
2. Lesson Proper
I have here a power point presentation and I
will discuss to you what is under food chain
and food web. I will randomly ask you some
questions so listen attentively and be
prepared.
What Is food chain? Does anybody know
the answer? Okay if none I will discuss what
is food chain.
Food chain
-Sequence in which energy is transferred
from one organism to another
The students who are on the hot seat with a
character of frog must go in front and
execute their roles in the story eating the
caterpillar and jumping
The students who are on the hot seat with a
character of Snake must go in front and
execute their roles in the story devouring
the frog and going to its shelter
The students who are on the hot seat with a
character of Eagle must go in front and
execute their roles in the story flying and
eating the snake
The students who are on the hot seat with a
character of young brave hunter must go in
front and execute their roles in the story
1. The story shows that different
species of an ecosystem interacts
with each other by eating other
organisms in order to gain energy
and survive.
2. The story tells us about how
organisms eat each other in order to
gain energy and survive.

5. -The energy flow from on trophic level to
the other is known as a food chain.
Producer
-Makes its own food through
photosynthesis.
Example: Grasses, ferns, trees and algae
Based on the story that I read earlier, who
was the producer?
Consumer
-Is an organism that feeds on plants or other
animals for energy
TOPIC 1: TYPES OF CONSUMERS
-Herbivores eats only plant
Based on the story telling, what organism
was the herbivore?
-Carnivores eat only animals
Based on the story telling. What organisms
were the carnivores?
-Omnivores are both plants and animals
Based on the story telling, what organism
was the omnivore?
-Detritivores eat dead organic matter.
TOPIC 2: FOOD WEB
-Food web are multiple food chains
-Shows many feedings relationship that are
possible in an ecosystem
TOPIC 3:TROPICAL LEVELS
-Is the position an organism occupies in a
food chain. It refers to food or feeding
organisms which eat other organisms to
obtain energy
The plant
The caterpillar
Frog, snake and eagle
The young hunter

6. 1. Primary consumer: eat producers
Based on the story what is the Primary
Consumer?
2. Secondary consumer: eats primary
consumers
Based on the story what is the secondary
consumer?
3. Tertiary consumer: eat secondary
consumers
Based on the story what is the tertiary
consumer?
4. Quaternary Consumer: Eat tertiary
consumer
Based on the story what is the quaternary
consumer?
5. Quinary Consumers: Eat Quaternary
Consumers
Based on the story what is the Quinary
consumer?
How organisms transfer energy through
trophic level?
-Each time an organism eats another
organism, energy transfer occurs.
- Food chains, food webs, and trophic levels
tell us how energy transfer occurs.
-Each step in the chains or webs represents
the transfer of energy.
- Each time energy is transferred from one
level to another, some energy is lost as heat
and less energy is available for organisms at
the next level
3. Wrap- Up
How are animals and plants dependent on
one another?
Caterpillar
Frog
Snake
Eagle
Hunter
Animals are consumers and they all depend
on plants for survival. Some eat plants
directly, while others eat animals that eat
the plants. In turn, some plants depend on
animals to help spread their seed.

7. Will someone sum up what you have
learned today?
food chains are a single path showing how
energy moves from organism to organism
through an ecosystem, while a food web is a
more complex network that maps the
multiple feeding relationships of each
organism in an ecosystem.
4. Value Integration
What moral value can you get from lesson
for today?
How can you show respect to the plants and
animals?
5. Application
Students will be divided into 4 groups. Each
group will be given pieces of print outs of
different organisms in a specific ecosystem.
You must construct its food chain using the
print outs and the group must paste it in a
Decomposing animal carcasses can also
provide nutrients for plants to grow.
We learned about how organisms interact
and survive by eating other organisms it is
also called the food chain where it is the
sequence in which energy is transferred
from one organism to another. Also, there is
what we call food web where it composes
multiple food chains. Food web and food
chains composes of producers which are
plants and consumers which are the
herbivores, carnivores, omnivores and
detritus. Also, we learned about trophic
level where in it is the position an organism
occupies in a food chain. Moreover, Energy
is transferred to one organism when it it’s
the other organism. But it is expected that
there would be less energy if the secondary
consumer will eat primary consumer.
Respect and Environmental cleanliness,
To build a love for nature and an
understanding of stewardship, encourage
young people to be playful and curious in
nature. Give them lots of opportunity to get
outside, investigate, talk about what they
observe, dig in, feel protective, and run
around.
Group 1- Terrestrial (Forest, deserts,
grassland)
Group 2- Lentic (Ponds and lakes)
Group 3- Lotic (spring, river, streams)

8. cartolina. And put the cartolina on the
board.
GROUP 1:
Owl-snake-bird-grasshopper-plant
GROUP 2:
Snake-frog-water insects-water plants
GROUP 3:
6. Generalization
Last question before we move on to our
evaluation
What is the Impact of food chain in our
daily life?
That is correct! Food chains are
important because they show the intricate
relationships in ecosystems. It is seen that
in food chains, each organism fills a
specific niche in an ecosystem. Food
chains reveal how each organism depends
on someone else for survival.
Group 4- Artificial (dams, garden, parks)
Food chains are important because they
show the intricate relationships in
ecosystems. They can reveal how each
organism depends on someone else for
survival. Food chains also display what
happens when a problem occurs and a
producer or consumer is lost. Entire
communities can collapse
IV. EVALUATION
In a 1 whole sheet of pad paper, using the food web constructed by each group students will create
their own trophic level based on their groups constructed food web.
