2. In humans or other organisms, every task in the
body requires the use of energy. In the cellular level,
body cells constantly need a steady supply of energy
to keep the organism alive.

3. Energy is also required to produce and
breakdown molecules, as well as to transport
products in and out of the cell. Removing
pathogenic bacteria viruses, and exporting toxins
and poisons out of the cell also require the use of
energy.

5. What is Bioenergetics?
• a subfield of science that study the concept of
energy flow within living systems.
•it deals with the intake, processing, and
expenditure of energy within the body.

6. What is Metabolism?
•is the synthesis and breakdown of complex molecules
that occur through chemical reactions that release
energy or require energy.
•collectively, metabolism can also be defined as all the
chemical reactions taking place inside the cells.

7. Components of Food Chain
•Producers
•Consumers
•Decomposers

8. Producers
•The producers in a food chain are the plants
(autotrophs), which take water and minerals from the
soil and carbon dioxide from the air.
•In photosynthesis, solar energy is captured by plant
leaves to convert water and carbon dioxide to sugar and
oxygen.

9. Consumers
•The consumers (heterotrophs), on the other hand, eat
plants and other animals. To produce energy from sugar
(glucose) through cellular respiration, they must take in
oxygen. Cellular respiration results to the release of
carbon dioxide and return of wastes (undigested
materials) to the environment.

10. Decomposers
•Small animals, fungi, and bacteria decompose
wastes and remains of dead organisms. These
decomposers act as recyclers of soil nutrients that
plants can use up again, ensuring the cycle of
matter in the ecosystems.

12. Energy flows in one direction and transforms from one
form to another. It flows through the ecosystem as
autotrophs absorb light energy to be converted into
chemical energy in the form of sugars. When heterotrophs
consume other organisms, the chemical energy is passed
on to their bodies. In the process of energy conversion,
some energy is converted into heat. Therefore, the flow of
matter and energy in organisms requires unending
interactions from the sun's one-way flow of energy through
the ecosystem and cycling of nutrients among producers,
consumers, and decomposers.

14. •Each part of the energy pyramid are called trophic
levels or energy levels.
•As energy transfers from one trophic level to
another, 90% of energy is lost.
•This means organisms only obtain 10% of the
energy to other organism they consume.

15. •The cycle completes through the decomposers.
When the consumers die, it is the decomposers’
job to break down its body and transfer its
nutrients to the soil.
•The cycle repeats.

17. Usually, a natural ecosystem always find its
way to maintain homeostasis but there are
damages that are beyond repair. For example, the
decline of planktons due to the melting of sea ice
directly affects the population of fishes that
depend on them for food. Due to scarcity of fishes,
seal population also declines directly affecting the
polar bear population. Due to climate change,
polar bears are now considered vulnerable to
extinction. This chain of events is called the
Domino Effect.
