Ecosystems: Biomes

​

Open Ended

Describe the ecosystem you live in.

The animals that see in the wild and the temperature and weather.

Biomes

• Large communities on Earth with similar climates and organisms

• Plants and animals are ADAPTED for a specific biome

• Biomes have changed many times during Earth’s history

• Humans have a major impact on biomes

This is a picture of all of the different biomes around the world

Abiotic vs. Biotic

• There are many factors that affect an ecosystem/biome.

• Some are living while others are not

Biotic Factors

There are things that are living. Animals, plant life, bacteria, fungus. Etc.

Anything that is or was living.

Open Ended

Multiple Choice

Which of the following is NOT a biotic factor?

• Temperature

• Animals

• Plants

• Bacteria

Abiotic Factors

These factors are non living. These are things that are NOT ALIVE.

Ex. Water, Temperature, Altitude, Sunlight, Soil, etc

Adaptations

• Animals will have to hunt at night to prevent water loss. (Kangaroo Rat)

• Plants will be shorter and have roots closer to the surface.

• Plants will have a waxy coating to prevent water loss (Cactus)

Multiple Choice

Taiga (Coniferous Forest)

• Also known as a coniferous or boreal forest

What is another name that the Taiga goes by?

• Rainforest

• Grasslands

• Coniferous Forest

• Oceanic Forest

Taiga (Coniferous Forest)

Many of the plants in this forest are going to be pine trees . These trees do not lose their leaves during the winter and remain green year long and have pine cones. (Hence the name coniferous.)

Multiple Choice

Why is the Taiga known as the Coniferous Forest?

• It has a lot of pine tree that have pine cones

• It has a lot of trees that loose their leaves in the winter

Many of the tree types in this forest are CONE bearing trees like PINE trees.

Tundra

• Extremely cold and dry

• Very short summers and long winters

• Temperature ranges from -40^oF to 68^oF

• Precipitation ranges from 6 to 10 inches a year
