Energy flows in one direction (up) through food chains. 

Constant growth that begins slowly then grows rapidly in a j shape is called:

Groups of individuals belonging to the same species that live in the same area. 

pH measures the concentration of 

primary succession usually occurs after a

Plants use carbon in the following processes except:

The largest number of individuals an environment can support is called:

The number of individuals per unit area is called:

A hypothesis must be:

When organisms of the same or different species attempt to use the same resource it is called:
