The two main abiotic factors that determine where organisms live are

• temperature and latitude

• altitude and precipitation

• temperature and precipitation

• soil type and precipitation

What are the two main factors that determine the climate of an area?

• precipitation and humidity
• temperature and air pressure
• wind conditions and humidity
• temperature and precipitation

Which two biomes have the least precipitation?

• tropical rain forest and temperate grasslan
• savanna and tropical dry forest
• tundra and desert
• boreal forest and temperate woodland

This biome is found around the equator and is home to a large amount of biodiversity.

• tundra
• desert
• grassland
• tropical rainforest

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

• tundra
• desert
• temperate deciduous forest
• tropical rain forest

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

• crystallization
• soilfrost
