What is ecology?
Transcript of What is ecology?
The living things are called the biotic factors of ecology. Together all of the living and non-living things in an area are called an ecosystem. This interaction produces different kinds of effects. The type of effect is controlled by the factors. Any single factor that limits the effect is called a limiting factor. This produces one of the laws of ecology. It is called the law of limiting factors and it says that the factor in least supply will determine the end effect regardless of how abundant all other factors may be. Think of a barrel in which one of the staves is shorter than all the rest. How full can you fill the barrel? We will be learning more about limiting factors when we study how nutrients are used in ecosystems. A nutrient is any chemical or compound which is used by an organism in order to survive and/or grow. Another law of ecology is that nutrients cycle Which means they go around and around The last law of ecology we'll talk about today has to do with energy. Energy doesn't cycle it goes through the ecosystem and leaves as heat. That wraps up our introduction to ecology. Any questions?
