The arrows in a food chain represent this.
What is a one-way flow of energy through the ecosystem?
Cactus wrens often build their nests in cholla cacti to avoid predators. This behavior does not hurt the cacti.

CO2 emissions result in trapping heat into the atmosphere
What is global warming/greenhouse effect?
This rule determines how much energy is passed down each trophic level in a food chain/web.
What is the 10% rule?
When producers are taken out of a food chain, how does this effect the other organisms in their chain?
What is first level consumers (primary) will decrease due to a lack of energy/food?

What is individual --> population --> community --> ecosystem --> biome --> biosphere?
The trends that are seen when two organisms that occupy the same niche.
What is one will out compete the other; one will thrive and one will die.
