WHAT ARE THE 6 NAMES OF MAJOR BIOMES?
- 1. Rain Forest
- 2. Desert
- 3. Grassland
- 4. Deciduous Forest
- 5. Boreal Forest
- 6. Tundra
WHAT TWO THINGS WITHIN A CLIMATE DETERMINE A BIOME?
WHAT ARE THE NAMES OF TWO TYPES OF RAIN FORESTS?
1. Temperate Rain Forest
2. Tropical Rain Forest
Having moderate temperature
WHAT ARE CHARACTERISTICS OF A TROPICAL RAIN FOREST?
- 1. Wet
- 2. Warm
- 3. A Lot of Plants
- 4. A Lot of Water
When tall trees form a leafy roof
A second layer of shorter trees and vines form this layer. Plants that grow well in shade thrive here.
An area that receives less than 25 cm of rain per year/the amount of evaporation is greater than the amount of precipitation.
An area that is populated by grasses and other nonwoody plants/receives between 25 & 75 cm per year
A grassland that is located closest to the equator
Trees that shed their leaves and grow new ones each year
Trees that grow seeds in a cone and leaves shaped like needles
Russian name for boreal forest
CHARACTERISTICS OF DECIDUOUS FOREST BIOMES
- 1. Animals Hibernate
- 2. Growing season 5-6 months
- 3. Cool mornings/hot days
CHARACTERISTICS OF BOREAL FOREST BIOMES
- 1. Smells like spruce & fir trees
- 2. Colder climate/winter with lots of snow and rainy/ wet summers
- 3. Water frozen most of year so trees have adapted to prevent water loss
An extremely cold and dry biome/ not deep piles of snow
Another name for the frozen soil in the tundra
CHARACTERISTICS OF A TUNDRA BIOME
- 1. Cold
- 2. Deep snow
- 3. No more water than desert
- 4. Short summer
- 5. Frozen soil
- 6. Shallow ponds
- 7. Mosses/grasses
- 8. Few trees/animals
NAMES OF THE 3 FOREST BIOMES
- 1. Boreal
- 2. Rain
- 3. Deciduous
HOW ARE THE 3 FOREST BIOMES SIMILAR?
- 1. Trees/ many habitats
- 2. Animals
HOW ARE 3 FOREST BIOMES DIFFERENT?
- 1. Amount of rain
- 2. Location
- 3. Temperature
- 4. Sunlight
- 5. Plants
- 6. Animals
WHERE DO MANY LARGE HERBIVORES LIVE? WHY?
Grasslands because there are so many plants
WHAt ARE THE NAMES OF EARTH'S MAJOR WATER (AQUATIC) BIOMES (OR ECOSYSTEMS)?
- Fresh water biomes:
- 1. Streams
- 2. Rivers
- 3. Ponds
- 4. Lakes
- Salt water/marine biomes/eco
- 1. Estuary
- 2. Intertidal zone
- 3. Neritic zone
- 4. Open ocean
- (Surface/deep zones)
HOW DOES CLIMATE DETERMINE A BIOME'S CHARACTERISTICS?
Climate limits the type of plants that can survive in the biome which in turn determines the kinds of animals that can live there
When an animal enters a stage of greatly reduced body activity similar to sleep
When the water on earth is heated by the sun's energy and is changed from a liquid to a gas
Water based ecosystems
WHAT ARE TWO TYPES OF AQUATIC ECOSYSTEMS?
- 1. Fresh water
- 2. Marine/Salt water
EVEN THOUGH MOST OF EARTH'S SURFACE IS COVERED IN WATER, ONLY A TINY FRACTION IS ________ WATER
WHAT ARE SOME CHARACTERISTICS OF FRESHWATER ECOSYSTEMS?
- 1. Some bodies are still water
- 2. Fresh, not salt water
- 3. Include a variety of habitats
- 4. Shallow compared to most bodies of salt water
An area found where fresh water meets salt water
A salty ecosystem between the highest and lowest tide lines
A salty ecosystem below the lowest tide lines/shallow water
WHAT ARE SOME CHARACTERISTICS OF MARINE ECOSYSTEMS?
- 1. Salty
- 2. Algae/plants food and shelter to marine animals
- 3. Animals such as: crabs; worms; clams; and fish
WHAT ARE THE NAMES OF EARTH'S 6 MAJOR LAND BIOMES?
- 1. Tundra
- 2. Grassland
- 3. Rain Forest
- 4. Desert
- 5. Boreal Forest
- 6. Deciduous Forest
