Enrichment Card
1. Yes, as long as the producers and the decomposers are present.
2. If there were no decomposers in an ecosystem, nutrients from
dead organisms could not be recycled and plants would not
have the raw materials they need for making food. Without food,
all organisms in an ecosystemwould not survive.
3. Destruction of balance in nature will occur and all living things
will die because they are interrelated to one another.

2. Feeding Interrelationships Among
Living Organisms
Task Analysis
Learning Competency: Observe and describe feeding
interrelationships among the living organisms
Subtasks:
1. Identify the producers and consumers in an ecosystem
2. Illustrate the feeding relationships between organisms
through a food chain / food web
Guide Card
Are you ready?
Wait, Kuya Pao! Let me
introduce myself, I’m Jumbo,
the everybody’s bestfriend.
Before we will start the I
Survived: A Sci Game Show.
Let us welcome our juries:
All living things or organisms need
food in order to survive. Only green
plants like me and other
photosynthetic organisms (like
algae) can produce our own food
using the energy of sunlight. Others
called us Autotrophs or self-feeders.
So, if you want food, just win the
game.

3. For the reward challenge, you will have the chance to win “EAT
ALL YOU CAN” in a famous food chain in a forest and in a pond.
Lastly, for the Immunity challenge, the winning survivor will grab
the food web showcase.
Hi! My name is Eagle, one of
the Heterotrophs or
consumers who ultimately
live in the energy produced
by Autotrophs. And I will
assure you castaways if you
surpass all the challenges,
you will have the chance to
visit my kingdom.
Decomposers as they called us. We
break down wastes and the remains
of dead plants and animals into
simple nutrients which are returned
to the soil. Others termed us
Recyclers also. If you lose the game
I will decompose you so win the
battle.
And for the much awaited prize
Food chain
consists of a
series of
animals that eat
plants and other
animals
Food web is an
overlapping
series of food
chain.

6. Assessment Card 2
Read the poem. Then illustrate the feeding relationship among the
organism cited in the poem through a food chain.
A Food Chain
Up sprang a frog
Where insects were eating leaves
Under a log
Then came a snake
And it swallowed the frog
Then came a hawk
Guess what it got?
