D. Science Concept: A food web is a pattern of overlapping and interlinked food chains. The energy pyramid illustrates how the amount of stored energy
from the sun is reduced as an organism gets away from the producer.
E. Process SkillsObserving, Describing, Differentiating
III. ProcedureA. ENGAGE

MotivationShow the illustrationHow many food chains are there in this illustration?
B. EXPLORE Setting of standards to be followed in doing the activity Group the pupils into four Let each group perform the activity.
C. EXPLAIN* Discussion / Analysis
Answer the following questions1. How many food chains are there in the illustration?2. Which is the producer?3. Which are the primary consumers?4. Which are the secondary consumers?5. Which get the greatest amount of energy among the consumers?6. Which get the least amount of energy?
Which is found at the base of the pyramid?
Which are found at the second layer?Which at the third layer?From the pyramid shown, which get the greatest amount of energy?
* GeneralizationWhen the transfer of energy from the food becomes interlinked, the
overlapping food chains now show a kind of relationship of flow known as food web.What happens to the amount of energy as it is transferred from one
consumer to another?How much energy do humans get when they eat higher order
consumer?
D. ELABORATEConstruct your own food web using the following animalsChicken, bird, rice plant, boy, lizard, snake
