1. From Deserts to Rainforests

2.  Biome: a large group of ecosystems (SPCEB) that share a climax community  All biomes are not the same  Tundra, tropical rainforest, desert  Biomes usually contain same plant life  Deserts usually have same animals and plants  2 most important factors in biomes are temperature and precipitation

4.  75% of Earth’s surface is water  Largest biome  2 types  Marine (saltwater/ocean)  Freshwater (lakes, rivers, ponds)

5.  Estuary: a coastal body of water where rivers meet oceans  Fresh water meets salt water  Can have an interesting population of animals here that can “tolerate” some salt/fresh water

6.  In food webs, producers (grass) was on the bottom of the pyramid  In aquatic biomes, “plankton” are on the bottom  They are the base of the aquatic food chain  Plankton: tiny orgnsms. That float in waters of the “photic zone”

9.  Land biomes  Closer to equator, biomes get warmer and wetter/drier  Further away from equator  Colder  Several different types of biomes  Temperate deciduous forest, taiga, tundra, desert, tropical rainforest, grassland
