*All living things are interconnectedinterconnected – survival of an organism depends upon it’s interactions with other living and nonliving things

*Species impact each other in complex ways because they are interdependentinterdependent

* We can divide the world into the living, bioticbiotic and nonliving, abioticabiotic

*Our planet has been shaped by not only the abiotic factors but the biotic factors as well

*There are 10 major land biomes and salt water and fresh water biomes.
