Marine Biomes-Contain saltwater. The type of organisms present is highly dependent on sunlight. Sunlight is needed for photosynthesis
Photic Zone-Sunlight can penetrate, Photosynthesis can occur
Aphotic Zone-Sunlight cannot penetrate

5. Terrestrial Biomes Latitude influences the climate of an area
Some latitudes receive more direct radiation than others
Temperature and precipitation have a huge affect on the climate of an area

8. Tundra
The tundra is a treeless area in the Arctic circle that is consistently frozen

Temperate Forests – Primarily covered by trees in a mild climate
Animals include:
Squirrels
Rabbits
Deer
Bears

13. Rain Forests
Rain forests have high amounts of precipitation and high temperatures
Near the equator, have a wide diversity of life
Contains many species of life that are deadly and poisonous
The rainforest is a very dangerous place
