Ecology: Chapter 2, Section 4 & 5 Biomes

A group of land ecosystems with similar climate and organisms

• 1. Rain Forest 
• 2. Desert
• 3. Grassland
• 4. Deciduous Forest
• 5. Boreal Forest
• 6. Tundra

1. Temperature

2. Precipitation

1. Temperate Rain Forest

2. Tropical Rain Forest

Having moderate temperature

• 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

• 1. Animals Hibernate
• 2. Growing season 5-6 months 
• 3. Cool mornings/hot days

• 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

• 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

• 1. Boreal
• 2. Rain
• 3. Deciduous

• 1. Trees/ many habitats
• 2. Animals

• 1. Amount of rain
• 2. Location
• 3. Temperature
• 4. Sunlight
• 5. Plants
• 6. Animals

Grasslands because there are so many plants

• 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)

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

• 1. Fresh water
• 2. Marine/Salt water

Fresh

• 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

• 1. Salty
• 2. Algae/plants food and shelter to marine animals
• 3. Animals such as: crabs; worms; clams; and fish

• 1. Tundra
• 2. Grassland
• 3. Rain Forest
• 4. Desert
• 5. Boreal Forest
• 6. Deciduous Forest
