The number of the same species in a given place at a given time. |
|
|
|
What are communities? |
Communities are different species at a given place at a given time. |
|
|

Homeostasis. |
|
|
|
How does energy move? |
Energy flows through the earth as a series of transfers. |
|
|

Metabolism is a total of energy reactions. |
|
|
|
What are the two categories of metabolism? |
Catabolism. Anabolism. |
|
|
|
What is catabolism? |
It is a reaction where energy is released. |
Digestion |
|
|
What is anabolism? |
A reaction where energy is built up. |
Exercise |

Prokaryotes are single celled organisms with no nucleus. Eukaryotes are single celled organisms with a nucleus. |
|
|
|
List Charles Darwin's view on mutation. |
Members of a population will compete for limited resources. Some heritable traits will improve survival. Those with adaptive forms of these traits will be more likely to reproduce and pass on traits to future generations. |
|
|
|
What does the adaptive trait do? |
Increases survivability and adaptive rate. |
|
|
|
***Define evolution. |
A heritable change in a line of descent over time. |
