nutrition
All that we physically are, ever were, or are
going to be is borrowed from the environment that we inhabit. This unique state
of indebtedness is primarily attributed to our nutrition intake. We must be
grateful to the earth’s crust for lending us minerals that strengthen our bones
and teeth and allow us to have electrical operations that drives nerve and
muscle function. We must also pay homage to plants for the carbohydrate forms
that power our operations and for the amino acids that make the protein in our
muscle.

protist
Many such functions in the protists are dependent on relatively elaborate
architectural adaptations in the cell. Phagotrophic feeding, for example,
requires more complicated processes at the protist’s cellular level, where no
combination of tissues and cells is available to carry out the ingestion,
digestion, and egestion of particulate food matter

annelid worms
scavengers feeding mainly on decayed organic matter
food is moistened by secretions from the mouth, then drawn in by
sucking action of the muscular pharynx
calciferous glands along the esophagus secrete
calcium ions into the gut and so reduce the calcium ion concentration formed by
the calcium in the soil - they also regulate pH of the body
after esophagus, food is stored temporarily in the thin-walled crop
before being passed on into the gizzard, which grinds the food into small
pieces

insects
insects also acquire water, vitamins, and minerals from their food.
Most terrestrial insects are highly-adapted for water conservation and get
most of the water they need directly from their food. A drop of morning dew
is usually sufficient for the few insects who actively drink water.

amphibians
Frog and toad diets consist of many types of insects, snails, worms and flies.
Some eat fish, and some of the larger frogs eat small lizards and mice. Some
species eat small fish. Large frogs will eat snakes and small mammals in the
tropics.

mammals
1. Ingestion – food is taken into
alimentary canal (gut) through the mouth
2. Digestion
– food is gradually broken down into simple molecules by teeth
and digestive enzymes
3. Absorption
– digested, soluble and simple molecules enter the blood at the
ileum
4. Assimilation – absorbed
nutrients carried by the blood and enter into body cells for releasing energy,
building structures and other functions
5. Egestion
–indigestible and unwanted food materials are removed from the body through the
anus

NON VASCULAR plants
angiosperm
gymnosperm
In a process called photosynthesis, plants use energy from
the sun to change carbon dioxide (CO2 - carbon and oxygen)
and water (H2O- hydrogen and oxygen) into starches and sugars.
These starches and sugars are the plant's food.
