• the scientific name for animals found in a particular region or habitat.   
• An ecosystem on a large/global scale
• is a community of plants and animals that interact with each other in a physical environment.

Which biome is characterized by low temperatures and low amounts of rainfall?

• Tundra
• Hot Desert
• Temperate Deciduous Forest
• Tropical Rainforest

Which biome, because of its climate, has the largest number of species of plants and animals?

• Tundra
• Rainforest
• Desert
• Pineforest

Which of the following in an ecosystem is classified as BIOTIC?

• Rock
• Sand
• Wind
• Tree

Which of these is an example of a service offered by the biosphere?

• Provides timber for construction
• A habitat for indigenous species.
• Producing food such as bananas
• Provides ingredients for medicine.

The rainforest can be seen as the lungs of the earth.  Why is this?

• They increase and decrease in size.
• The act as a carbon sink.
• Through photosynthesis, they convert carbon dioxide into Oxygen.
• They need moisture to operate effectively.

Which of these is a local factor that effects biome distribution.

• Altitude
• Temperature
• Sunshine Hours
• Lattitude

There are two main types of rainfall helping to provide reliable rainfall at the equator and in highland areas.  These are.

• Relief and cyclonic rainfall
• Convectional and low pressure rainfall
• Coastal and highland rainfall
• Convectional and relief rainfall

Why is there a lot of biodiversity in tropical rainforests? 

• Reliable rainfall and warm temperatures.
• Cold temperatures and low rainfall.
• Lots of sunlight hours and poor quality soil
• High altitude and high concentration of sunlight

Why is the soil in the rainforest so good for vegetation growth?

• No sunlight reaches the soil keeping it cool.
• Leaf litter decays returning nutrients to the soil.
• Deforestation has helped to protect the soil
• It is not damaged by humans.
