Adaptation
biosphere

2. Where on Earth do organisms live?
Biosphere is the part of Earth that can support living things.
Examples of biospheres: deserts, oceans field, beaches, grassy yards, forests, mountain tops, lakes
Have scientists discovered all organisms that now live on Earth?
Give an example of how you interact with other organisms and the environment in the biosphere:

3. Variety among living things
Look at the pictures on page 8. They all have some things in common:
they are made of cells.
they require a source of energy
they reproduce
Adaptation is a characteristic that enables an organism to survive and reproduce in its environment.
Species is a group of very similar organisms whose members can mate with one another and produce offspring that are able to produce offspring.
*You should know that each species has a two part scientific name:
Horse is Equus caballus

4. Adaptations

5. A lion is a carnivore, an animal that preys on other animals
A lion is a carnivore, an animal that preys on other animals. A horse is an herbivore, an animal that eats plants. How would you expect the teeth of these animals to differ?

6. The lion’s teeth will be long, sharp and pointed and adapted to biting and tearing chunks of meat.
The horse’s teeth will be flatter and adapted to cutting and grinding grass.

7. Species
Individuals in the same species often don’t look exactly alike. They can be
A different color
Size
Shape
Misconception- although some organisms may look similar they may be a different species. Ex: horse and donkey

8. The most important characteristics that scientist use to group organisms is their ability to mate with one another.

9. How do scientists group organisms?
Scientists sort organisms into groups with similar characteristics. This makes it easier to study.
Scientists divide all Earth’s organisms into six main groups called kingdoms.

10. Classification The grouping of things according to their similarities.
Looking at pages In which group would organisms have very similar characteristics but cannot mate with one another.

11. The Six Kingdoms
Scientists did not have powerful microscopes so they would use two kingdoms: plant and animals
After developing tools, scientists discovered bacteria.
Bacteria- single-cell organisms that do not have a nucleus. Plants and animals do.
So they grouped bacteria into their own kingdom.

12. Archaebacteria http://dictionary.reference.com/browse/archaebacteria
Includes bacterial that live where most other organisms cannot. No oxygen or in water that has lots of salt or is very hot.

13. Eubacteria http://dictionary.reference.com/browse/eubacteria
All other bacteria. They live in almost every environment, including your body!
There are more bacteria in your mouth than there are people on Earth!

14. Protists 200,000 know species Mostly one-cell organisms.
Contain a nucleus
Animal like
Energy by eating other organisms
Ameba is an example
Chlorophyll
Make their own food-photosynthesis
Algae

15. Fungi Mostly many celled organisms Moist, dark places Two types fungi
Mushrooms
Mold
Their cells are connected by thread like stands call hyphae
One single mushroom in oregon has a web of hyphae that spreads the size of 1,665 football fields

16. How are plants and animals classified?
Plants make their own food
Animals get energy from other living things
Plants are divided into two groups:
Vascular plants-have cells that from tubes for carrying water and nutrients throughout the plants.
Non vascular plants-do not have tubes

17. Plants Non vascular vascular Moss Seed Seedless Gymnosperms
Angiosperms
Gymnosperms

18. Animal classification
Animals are multi cellular
Cannot make their own food
95 percent of all animals are invertebrates
Do not have a backbone.
What is a chordates?

20. Warm up #4
Why is it easy to recognize members of the echinoderm phylum?
a. They have tentacles
b. They are segmented
c. They have five parts
d. They are fan-shaped
