The levels of taxonomy
Levels of Taxonomy
3 Domains of LIfe
Bacteria, archaea, and eukarya
Recipe book for organisms
The sum total of all chemical reactions that occur in all organisms.
Requires energy in the form of ATP.
2 types of reactions
anabolism: building up
catabolism: breaking down
maintaining a constant internal environment that is within a physiological rank
They are producers, which means they make their own food.
They are consumers, which means that they need outside sources for their means of consumption.
They are heterotrophs. They eat food from outside sources, but they can break down organisms for food and quickly return the nutrients back to the environment.
Bacteria that are prokaryotic, extremely small, and unicellular. They also live in extreme habitats.
Bacteria that is normal and cyanobacteria. They are also unicellular, prokaryotic, and are considered to be producers and decomposers. They make food by means of photosynthesis.
Amoeba, paramecium, and euglena are considered this. They are unicellular, eukaryotic, and considered to be producers and consumers.
Produces food by means of photosynthesis. They also have a primitive eye that can only detect the difference between light and dark.
Most of these are multicellular, eukaryotic, decomposers, and possibly represent the largest organisms on Earth.
The only fungi that is considered to be unicellular.
Trees, grass, and corn is considered to be this. They are multicellular, eukaryotic, and producers.
Insects, sea sponges, and worms are considered this. They are multicellular, consumers, and eukaryotic.
The Scientific Method
3. Experimental Phase
4. Gather data
Process of testing the hypothesis by having a controlled group and an experimental group.
The test that is done to prove or disprove the set hypothesis must be repeatable.
This is an "educated guess" that must be testable and can be done numerous times.
