Land Biomes

Which biome covers most of the land mass near Earth's equator?

• tundra

• desert

• grassland

• tropical rainforest

Which biome has the largest number of species of plants and animals (highest biodiversity)?

• tundra

• desert

• tropical rainforest

• pine forest

One characteristic of the tundra is that it has a layer of permanently frozen soil though which no tree roots are able to grow. This characteristic is known as:

• glaciation

• permafrost

• crystallization

• soilfrost

Which biome contains large populations of grazing herbivores, like cows and bison, few species of birds, and deep, rich soil but few trees?

• taiga

• tundra

• deciduous forest

• grassland

The most important abiotic factors when studying biomes are...

• Soil and Freshwater

• Producers and Consumers

• Native Plants and Animals

• Precipitation and Temperature

Which biome has deciduous trees (that lose their leaves in the fall)?

• Temperate Forest

• Rainforest

• Grasslands

• Taiga

Which biome has 4 seasons?

• Taiga

• Tundra

• Tropical Rainforest

• Temperate Forest

Which biome is home to cacti, scorpions, coyotes, kangaroo rats, and lizards?

• Desert

• Grasslands

• Temperate Forest

• Taiga

lichens, mosses, grasses, and other low-growing plants are common vegetation in this biome due to the permafrost, low rainfall, and very cold temperatures.

• Desert

• Taiga

• Tundra

• Grasslands

What term describes the living parts of an ecosystem?
