What is an organism?
100
Food chains, food webs, and energy pyramids.
What are diagrams that show the transfer of energy from one organism to the next within an ecosystem?
100
The level of an energy pyramid that holds the primary consumers, 1st order heterotrophs.
What is the second level from the bottom?
100
The highest number of a population an area can hold.
What is carrying capacity?
200
A relationship in which organisms of the same population help each other to survive.
What is cooperation?
