| | Energy Flow in Ecosystems
|
| | With a few exceptions, all ecosystems depend on solar energy as a primary energy source. Primary productivity is the result of energy captured by producers. Some of this energy is lost when producers, such as plants, use energy for respiration. Learn more here - use the arrows at the bottom of the screen to navigate this great tutorial. |

| | Intro to Ecosystems
|
| | An ecosystem is a way of looking at a biotic system. It combines the physical environment, which includes chemical nutrients and energy, with the biotic environment, the living organisms. Learn more here - use the arrows at the bottom of the screen to navigate this great tutorial. |

| |
| | Communities
|
| | A community is a group of species living in the same environment. Within each environment are species of plants, animals, fungi, protists and bacteria. In community ecology, the focus is on a set of species, often of the same type, living in a particular environment.

| |
| | Organization of Communities
|
| | Species within a community may interact in various ways. These interactions can be categorized by the possible effects two interacting species may have on each other, positive (+), negative (-), or neutral (0).

| |
| | Succession in Communities
|
| | Communities change over time as a result of several factors including physical disturbances, climatic change and invasion of new species. Following a major disturbance, a community undergoes a semi-orderly change in species composition over many years. Learn more here! |

| |
| | Population Growth
|
| | If additions to populations exceed losses, a population has the potential to increase in size exponentially. Learn more here - use the arrows at the bottom of the screen to navigate this great tutorial. |
| |
| | Population Size Regulation
|
| | A population regulating factor which is independent of population size is termed density-independent. One which is influenced by population size is termed density-dependent. Learn more here - use the arrows at the bottom of the screen to navigate this great tutorial. |
