This document compares and contrasts plant and animal nutrition. It defines nutrition as the assimilation of food materials that enable growth and survival. Organisms are either autotrophic, producing their own food, or heterotrophic, requiring food from external sources. Nutrients include minerals, essential amino acids, and cellular respiration which breaks down food for energy. The stages of digestion in animals are ingestion, digestion, absorption, and defecation. Herbivores eat plants while carnivores eat other animals. Ruminants and pseudoruminants have specialized digestive systems to break down plant matter.

1. PLANT AND
ANIMAL
NUTRITION
JERMIELYN SALVADOR

2. MELCS
Compare and contrast the following ptocesses in plants
and animals: reproduction, development, nutrition, gas
exchange, transport/ circulation, regulation of body fluids,
chemical and nervous control. immune system, and
sensory and motor mechanisms.

3. LESSON
OBJECTIVES
After going through thids module,
you are expected to:
01.
02.
03.
Identify the parts and
functions of organs and orga
system in the axquisition of
nutrient both in plants and
animals;
Distinguish the processes
and/or stages of acquiring
nutrition oh both plants
and animals and
Conpare and contrast
plant and animals

4. NUTRITION
is defined as the assinmilation of food
materials by living organism that enable them
to grow, maintain themselves, and
procedures.” (Truswell, A. Stewart, Caroenter,
Kenneth and Shell Esmond E.., 2020)

5. Organism requite
nutrients for the daily
survival particularly for
their cell growth and
repair. Nutrients are
chiefly procured form the
environment.

6. 2 Types of Organism
based on their
process of
acquirinng foods:
Autotrohic Organisms- those the
nanufacture their own foods.
1.
heterotropic Organisms- those that require
foods from other sources (bacteria, fungi
and other animals since thse organisms do
not manufacture organice subtances.)
2.

7. Another way living organisms
are classified is according to the
energy source they utilize
Phototrophic or photosynthetic are organisms that trap light
energy and convert it to chemical energy.
Chemoautotrophic, or chemosynthethic are oraganism that
utilize inorganic or organic compounds to supply their
energy requirements.
Lithotrophic are organisms that utilized the electron-donor
materials to form reduced coenzymes consist of inorganic
compounds.
Organotrophic are organisms that utilize organic materials.

8. ESSENTIAL NUTRIENTS
What is it?
nutrients that cannot
be created by
animals’ metabolism
must come from food

9. inorganic essential nutrients
that must also be obtained from
food. Minerals help in cell
structure and regulation: they
are also considered co-factors.
MINERALS
must be produced from food
and cannot be systhesized by
the body. The human body can
synthesize only 11 of the 20
required amino acids. The rest
must be obtained from food.
ESSENTIAL
AMINO ACIDS

11. Cellular respiration
is the process of obtaining energy
used for metabolism from the
breakdown of food.
WHAT IS IT?

12. Animals can be classified as
*frugivose (fruit- eaters)
*granivores (seed- eaters)
*nectivores (nectar feeders)
*folivires (leaf eaters
01
HERBIVOR
“eater of everything”
02
OMNIVORES
*Obligess carnivores
*Faultative
carnivores
03
CARNIVORES

13. The process of Digestion can be
summarized as follows:
Ingestion (eat food )---- Digestion (breakdown of food)---- Absorption
(extraction of nutrients from the food)---- Defecation (renoval of waste
products)

14. INVERTEBRATE
DIGESTIVE SYSTEMS
a form of digestion that takes place
within the cytoplasm of the organism
takes place in animals without a
digestive tract, in which food items are
brought into the call for digestion
INTRACELLAR
DIGESTION
a process wherein animals feed
by secreting enzymes through
the cell membrane onto the food.
EXTRACELLULAR
DIGESTION

15. MONOGASTRIC
DIGESTIVE
SYSTEM
MONOGASTRIC ANIMALS
have a singlen stomach that
secretes enzymes to break
down food into smalles
particles

16. RUMINANTS
DIGESTIVE
SYSTEM
RUMNANTS are those animals that
have four stomachs. They eat plant
matter and have symbiotic bacteria
living within their stomachs to help
digest cellulose.

17. PSEUDO-
RUMINANTS
DIGESTIVE SYSTEM
similar to ruminants but have a three-
chambered stomach. The symbiotic
bacteria that help them to break down
cellulose are found in the cecum, a
chamber close to the large intestine.

much!
