5. WARM UP
Arrange the following organisms to show
who eats whom
- killer whale
- cod fish
- krill shrimp
- algae
- leopard seal
5
6. Answer the following questions:
1. What is the source of energy in
the ecosystem?
2. What might happen to the other
organisms if algae were removed
from this group?
3. What might happen if the killer
whales were removed?
4. Are there any organisms in this
group that eat more than one
kind of food?

Photosynthesis
•Chemical reaction where green plants
use water & carbon dioxide to store the
sun’s energy in glucose
•ENERGY is stored in glucose
•Glucose is stored as starch in plants
13. 13
Consumers that eat producers
to get energy:
•Are first order (1st) or
primary consumers
•Are herbivores (plant-
eaters)
14. 14
Most of the
energy the
primary consumer
gets from the
producer is used
by the consumer.
15. 15
Some energy in the
primary consumer is
STORED & not lost
to the atmosphere or
used by the
consumer itself.
This energy is
available for another
consumer (predator).
16. 16
A Consumer that Eats Another
Consumer for Energy:
•Is called a secondary or
2nd order consumer
•May be a carnivore or
a omnivore
•May be a predator
•May be a scavenger
17. 17
Some of the
energy is lost as
heat, but some
energy is stored
and can passed
on to another
consumer.
18. 18
A consumer that eats a
consumer that already ate a
consumer:
•Is called a 3rd order
or tertiary consumer
•May be a carnivore or
a omnivore
•May be a predator
•May be a scavenger
19. 19
Consumers that eat producers
& other consumers
Are called
omnivores
Omnivores
eat plants
and
animals
20. 20
Consumers that hunt &
kill other consumers are
called predators.
The animals that are
hunted & killed are
called prey.

Energy Pyramids Show
When an organism eats, it
obtains energy, then uses
a lot of energy in life
process like growth and
movement.
This means that only part
of their energy is available
to the next organism in
the food web.
Only about 10% of the
trophic level’s energy is
transferred to the next
level.

36. VIDEO PRESENTATION ANALIZATION
1.What is the video clip all
about?
2.What are the organisms living
in the Great Barrier Reef?
3.What do you think will happen
if an oil spill leaked into the
Great Barrier Reef? How can it
affect the whole biosphere?

37. EVALUATION
Directions: Identify the
following:
1.The main source of energy
in the ecosystem
2. The transfer of energy from
the sun to producer and to
the primary and higher order
consumers.
