22. Strategies
Organisms survive because of evolved adaptations.
The adaptations are evident in the cells, tissues, organs and organ systems
of every living thing.
24. Organ Systems
Respiratory, Reproductive, Nervous,
Circulatory, Endocrine, etc are all
pretty much identical to human
form and function. (Match these to
your organisms’ MRS GREN
requirements.)
Digestive System has unique
adaptations.
25. Organ Systems
Respiratory, Reproductive, Nervous,
Circulatory, Endocrine, etc are all
pretty much identical to human
form and function. (Match these to
your organisms’ MRS GREN
requirements.)
Digestive System has unique
adaptations.
Koalas have a long caecum - an
offshoot of the large intestine.
This organ allows more time for
bacteria to break down the
fibers of the eucalyptus leaves,
which are normally toxic.
26. Organs Caecum - extra loop of the
large intestine, full of
cellulose-digesting bacteria.
What does the organ DO
to enable the organism to
survive in your biome?
27. Organs Caecum - extra loop of the
large intestine, full of
cellulose-digesting bacteria.
What does the organ DO
to enable the organism to
survive in your biome?
28. Tissues
Intestinal Villi - increase the surface area of
the interior wall of the intestine. Increases
the ability of the intestine to absorb
nutrients from food.
What does the
tissue DO to
enable the
organism to
survive in your
biome?
29. Specialized Cells
Epithelial Cells in the small intestine.
What do the
specialized cells
DO to enable the
organism to
survive in your
biome?
32. Organ Systems
Specialized Digestive
System
Crop - mixes food with
saliva and water.
Gizzard - muscular
organ that grinds food,
often using small
stones that the bird
has swallowed.
33. Specialized Organs
Eagles have 4 color receptor cells in their eyes,
compared to our three, allowing them to see into the
ultra-violet spectrum. The have sharper focus and
better long-distance vision that humans.
36. Apply This Information
You need: At least 2 examples of Primary,
Secondary and Tertiary Consumers for your
biome.
One of them might be your leading character.
