Biotic

Living

3

Communities are?

Different species interacting

4

How do decomposers get their food?

By feeding on the dead

5

Competition?

Occurs when organisms use the same limited resources

6

Symbiosis

A close physical and long term relationship between two organisms of different species

7

Mutualism

A relationship between two organisms in which they both benefit

8

Commensalism

Relationship between two organisms is which one is not affected, and the other benefits

How much energy is transferred in the flow of energy?

10%, 90% is lost

22

What is the carbon cycle?

The process of carbon dioxide cycled through an ecosystem by decomposers and photosynthesis

23

What is 'carrying capacity'?

The maximum of organisms in a population that can be sustained by an ecosystem

24

Epicormic buds

Buds beneath the bark that will grow into new branches after a fire has passed

25

Enhanced greenhouse effect

The burning of fuels that release gases into the air that trap heat, resulting in global warming
