BIOMES
VOCABULARY
• BIOME – a large region characterized by
a specific climate and certain types of
plants and animals.
• ECOSYSTEM – a community of organisms
and their nonliving environment
TYPES OF BIOMES
• LAND BIOMES
• MARINE BIOMES
LAND BIOMES
• Deciduous Forest
• Coniferous Forests
• Rainforest
• Grasslands/Savannas
• Deserts
• Tundra
WHAT DO YOU THINK YOU SEE
IN A FOREST IN CT?
FORESTS
• Temperate Deciduous – trees shedding
their leaves.
• Variety of animals like bears, snakes, and
woodpeckers.
• Climate: hot Summers, cold Winters, Rainfall
throughout the year
• Connecticut is part of this biome.
WHAT DO YOU THINK YOU
WILL SEE IN A FOREST WITH
MANLY PINE TREES?
FORESTS
• Coniferous Forests – trees keep their
leaves year round aka evergreen trees.
• Most trees are conifers – produce cone
(pine cones)
• Animals living in these forests are
squirrels, deer, moose, and porcupines.
• Climate: long cold Winters, short Summers,
frequent Rain
WHAT DO YOU THINK YOU
WILL SEE IN A RAIN FOREST??
FORESTS
• Tropical Rain Forest – great biological
diversity.
• Can have 100 types of trees.
• Some animals live on the ground, but
most live in the canopy.
• Canopy – treetops.
• Climate – hot, humid, rains daily
– Plants: Jungle (think Tarzan), very tall trees,
thick vegetation on the ground, dense canopy
– Animals: parrots, Apes, Toucans, Monkeys,
Leopards, other predatory Cats, Snakes
FORESTS
• Temperate Rain Forest -
WHAT IS A GRASSLAND?
WHAT DO YOU THINK YOU SEE
THERE?
GRASSLANDS
• Temperate grasslands – North America
– Our farmlands
– Snowy winters, warm to hot summers
• Savannas – Africa, India, South America
• Climate: long dry periods with occasional fires
• Plants: several species of Grasses, scattered
Trees, and Wildflowers
• Animals: burrowing Animals – Rabbits,
Moles, & Rodents, grazing Animals – Buffalo,
Zebras, and Giraffes, Lions, and Hyenas
DESERT
• Little to no plant life.
• Long periods without rain.
• Extreme temperatures, hot days, very
cold/freezing nights
– can snow at night!!!
• Jack rabbits, kangaroo rats, lizards,
venomous snakes.
• Cacti, tumbleweeds
TUNDRA
• Treeless plain found in the Arctic or on top
of mountains.
• Low winter temperatures, short cool
summers.
• Animals include musk oxen, bears, wolves,
and caribou
• Climate: Cold, ground stays covered in snow,
permafrost – permanent frozen layer of ground,
scarce rainfall, very short summers
MARINE BIOMES
Marine Ecosystems
• Shaped by: temperature, water depth,
and amount of sunlight that passes into
the water.
• Largest animals are blue whales.
• Smallest animals are plankton –
microscopic organisms floating near the
surface of the water.
MARINE ECOSYSTEMS
• Intertidal Zone
• Salt Marshes
• Estuaries
• Coral Reefs
• Sargasso Sea
• Polar Ice
Intertidal Zone
• Where the ocean meets the land.
• It’s exposed to air part of the day.
• Animals living in this zone have adapted to
being exposed to air and to keep from
being washed away by the waves.
Intertidal Zone (continued)
• Land types in this area are: mudflats,
sandy beaches and rocky shores.
• Mudflats have worms and crabs.
• Sandy beaches have worms, clams, crabs,
and plankton.
• Rocky shores have starfish, barnacles, sea
squirts.
Salt Marshes
Estuaries
• Where freshwater from streams and
rivers spills into the ocean.
• Amount of salt in the water is always
changing.
• Plants and animals must be able to survive
in this changing environment.
