BIOMES CONTAIN MANY ECOSYSTEMS

1
BIOMES CONTAIN MANY ECOSYSTEMS

• REGIONS OF EARTH ARE CLASSIFIED INTO BIOMES
• Biomelarge geographic areas that are similar in
  climate have similar plants animals
• 6 major biomes on Earth
• Climate (long term weather pattern of region) is
  important factor in land biomes, so is available
  water, temperature and soil type.
• WATER COVERS MOST OF EARTHS SURFACE
• About 75 of Earth is covered by water
• Freshwater saltwater biomes
• Plants are producers for water near land while
  deep ocean water relies on tiny photosynthetic
  microorganisms called phytoplankton

TAIGA TUNDRA

• These are characterized by long, cold winters and
  short summers. (Arctic tundra can be 50oC)
• Tundra gets little rain (lt25cm/yr), but is wet
  because cold keeps water from evaporating
  permafrost(deep frozen soil) keeps trees from
  taking root, so just little moss, grass, lichen
  shrubs. Find rodents, caribou, musk ox, grizzly
  bears, foxes, owls.
• Taiga has more rain, more snow on ground
  insulating soil from permafrost.
• Have CONIFEROUS trees (needlelike leaves making
  food all year). Wood leaves of trees feed
  insects, seeds feed birds squirrels.
• Deer, elk, snowshoe hare, beavers, lynx, owls,
  bears wolves live here.

3
Desert Grassland

• Found in middle latitudes not much precipitation
  to support trees for either.
• Some deserts are cold, some hot but all have dry
  soil desert plants (cacti) animals (lizards)
  can get by on very little water. Also have
  kangaroo rat, snakes, foxes owls.
• Grassland had moderate rainfall (50-90cm/yr)
  enough for grasses but not forests. Warm summers
  may have cold winters.
• Seed-eating rodents, bison, horses, gazelles,
  zebras, wolves, tigers lions are found in
  grasslands.

4
Temperate Tropical Forest

• Temperate forest grow where winters are short
  75-150cm of water/yr. Most made of Deciduous
  trees (broad leaves, drop in winter-oak,maple).
  Supports wide variety of forest animals. Some
  have coniferous trees (Pacific Northwest-redwoods
  spruce wet winter dry summer).
• Tropical forests near equator, warm all year and
  wettest biome (250-400cm/yr). Leaves all year
  soil is poor in nutrients. More animals plants
  than anywhere else. Trees grow close together
  support many tree dwelling animals (monkey,
  snakes, birds) plants (orchids vines).

FRESHWATER BIOME

• Ecosystem of freshwater biomes affected by
  quality of landscape around them. (depth of
  water how fast water runs, etc., determines
  types of plants animals)
• Ponds lakes have still water Ponds have many
  plants, deeper lakes have more phytoplankton.
  Insects, shellfish, fish and land animals feed
  within them.
• Estuary water ecosystem thats a transition
  between fresh saltwater biomes. Lower end of
  river that feeds into ocean, where fresh salt
  water mix. Marshes wetlands are both
  estuaries. (nurseries of sea calm waters
  attract marine animals to reproduce here).
  Seaweed, marsh grasses, shellfish, birds thrive
  here.

MARINE BIOMES

• Saltwater biomes coastal ocean, open ocean, and
  deep ocean. Beaches tidepools are part of
  coastal ocean biome. Crabs clams thrive in
  ever-changing conditions of coastal areas.
• Open ocean gets less sunlight has cooler
  temperatures. Many fish, marine animals, and
  floating seaweed live in upper ocean. No plants
  in open ocean, producers are phytoplankton.
• Deep ocean is much colder darker. Animals feed
  on each other or on material falling down from
  upper levels of ocean. Many of deepest organisms
  are microscopic and many are still unknown.
