Metabolism
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
Homeostasis
maintaining a constant internal environment that is within a physiological rank
Autotrophs
They are producers, which means they make their own food.
Heterotrophs
They are consumers, which means that they need outside sources for their means of consumption.
Decomposers
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.
Archaebacteria
Bacteria that are prokaryotic, extremely small, and unicellular. They also live in extreme habitats.
Eubacteria
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.
Protista
Amoeba, paramecium, and euglena are considered this. They are unicellular, eukaryotic, and considered to be producers and consumers.
Euglena
Produces food by means of photosynthesis. They also have a primitive eye that can only detect the difference between light and dark.
Fungi
Most of these are multicellular, eukaryotic, decomposers, and possibly represent the largest organisms on Earth.
Yeast
The only fungi that is considered to be unicellular.
Plantae
Trees, grass, and corn is considered to be this. They are multicellular, eukaryotic, and producers.
Animalia
Insects, sea sponges, and worms are considered this. They are multicellular, consumers, and eukaryotic.
The Scientific Method
1. Observations
2. Hypothesis
3. Experimental Phase
4. Gather data
5. Conclusion
6. Publish
Experimental Phase
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.
Hypothesis
This is an "educated guess" that must be testable and can be done numerous times.
