next level of clasification below kingdom
|
|
class
|
Classification level below phylum
|

|
|
how do scientists classify organisms?
|
First observe the organism
Then they compare and contrast with known organisms. similar organisms are placed in same group. |
|
Why is it important to classify?
|
Makes it easier for scientists to communicate clearly.
helps organize information so easier to classify new organism. |

One advantage of a classification system?
|
makes it easier for scientists to communicate clearly.
|
|
What kids of observations did scientists use at first to group organisms into a phylum or a class?
|
Looked at how they were similar.
|

|
animals with backbones that surround a spinal cord
|
|
What 3 features that make animals different than other organisms?
|
1.multicellular - more than one cell.

|
How are reptiles different than mammals
|
No hair or fur
tough driy skin with scales cold blooded lay eggs |
|
body temperature changes as the temperature of the air or water changes
|
cold-blooded
|
|
How is life cycle different than mammal.
|
young reptiles look like parent
lay eggs live on own once hatched |

warm-blooded
many organs, eyes, tongues and bones |
|
What makes a bird different?
|
feathers
|

|
shaped like them.
front edge is thick and curves to thin back edge |
|
How is the bird life cycle different than reptiles?
|
must feed their young
|
|
amphibian examples
|
frogs, toads and salamanders
|
|
How are amphibians like reptiles
|
cold blooded
shape |
|
how are amphibians different than reptiles?
|
amphibians have soft moist skin and it can absorb water & oxygen
|
|
what makes an amphibian so different than other mammals?
|
it goes through metamorphosis
|
|
large change in body from birth to adult
|
metamorphosis
|
|
only class of vertebrates made up only of water-living animals is?
|
fish
|
|
How do fish get oxygen?
|
through gills
|
|
Why do fish have a slimy coating?
|
so water flows past them.
|
|
Life cycle of fish is similar to?
|
life cycle of reptiles. Once hatched feed themselves
