1. Biomes, and Aquatic Ecosystems By: Mattias Knapp and that Other Guy

2. What is a biome?

3. What is a Biome? major terrestrial ecosystems that cove most of the earth they are classsified by o types of of plants o types of animals o types of climates  Different animals live in same biome some follow lines of lattitude o notice how simmilar biomes are at similar lattitudes

4. ----------Types of Biomes---------

5. Tundra in top lattitudes or mountains bitterly cold permafrost covers ground o little plant life grows o not much melts animals aren't very diverse (low biodiversity)

6. Coniferous Forest cone-bearing evergreen trees northern part called taiga o conical shape of the trees prevents snow collecting o needle leaves prevent moisture loss lower latitudes considered temperate rain forests o a little biodiversity

7. Temperate Deciduous Forest broad-leaf deciduous trees moderate precipitation cold winters hot summers shed leaves in autumn high biodiversity many animals conserve energy in winter some birds fly to warmer areas

8. Temperate Grassland deep, nutrient rich soil cool winters very few tall plants o seasonal drought o occasional fires o large grazing anmals varied grass types high biodiversity

9. Chaparral coastal biome mild rainy winters hot dry summers many fires o woody shrubs often set abblaze  they are specifically adapted for this little biodiversity

10. Desert very dry temperature varies between deserts o some have no plant life o some have scattered shrubs and cacti organisms adapt very well for little water

11. Savanna grasslands with scattered trees many grazing animals many predators warm alternating wet-dry seasons o drought during dry seasons  animals adapted for this

12. Tropical Forest near equator receive a lot of rain the highest biodiversity of all biomes o plants grow on each other in layers o hundreds of thousands of animal species being cut down almost to extinction

13. ----------Aquatic Ecosytems---------

14. standing water wide range of sizes large lakes are divided into zones o photic zone  photosynthetic plants and microorganisms o aphotic zone  darker murkier areas o benthic zone  bottom Lakes and ponds

15. Streams and Rivers flowing fresh water different organisms than in lakes changes from source to destination o shallow at source o deeper and wide at end o more organisms live at the end

16. Estuaries where rivers merge with ocean warmer and saltier than rivers rich diversity in water and on surrounding land o salt marshes o mangrove swamps

17. Ocean Zones Intertidal Zone Neritic Zone o continental shelf o photic zone Oceanic Zone o benthic zone o pelagic zone  photic zone  aphotic zone

18. Coral Reefs marine tropical rain forests many marine species inhabits a coral reef all the invertebrates are in coral reefs visually amazing and diverse ecosystem reefs are formed by colonies of coral polyps o coral-an animal that makes an stone like exoskeleton

19. Deep-sea Vents tubes where hot gases rise sunlight can't reach that far down o adaptions to get energy from sulfur o these are called prokaryotes prokaryotes--->tube worms and clams--->crabs
