6.L.2.3 Biomes 2022

An area is semiarid, has few trees, and is home to ground-nesting birds. This area is

MOST likely part of which biome?

• tundra

• taiga

• grassland

• desert

In the geologic past, abiotic factors such as volcanic eruptions have had an impact on the

availability of resources. How can volcanic eruptions impact the availability of resources?

• by decreasing the thickness of soil

• by causing more heavy rains to erode topsoil

• by disrupting the sunlight from reaching producers

• by causing the surface of Earth to be warmer than usual

How are a tundra and a desert similar?

• They both get too little rainfall to support large plants.

• They both get too little sunlight to support many plants.

• They both have healthy soil to support a wide variety of plants.

• They both have a range of temperatures to support a wide variety of

  plants.

Why are organisms in the open ocean more likely to perform

photosynthesis than organisms in a forest stream?

• There is more exposure to sunlight in the ocean.

• There is more exposure to sunlight in the forest.

• More precipitation falls over the ocean.

• More precipitation falls in the forest.

This table shows the components of a terrestrial food web and a

description of each component.

Component Description

E returns nutrients back to the ecosystem

F uses carbon dioxide and water to make glucose

G acts as an abiotic factor in the ecosystem

H produces carbon dioxide as a waste product

A student is labeling a sketch with the correct term for each component. What label

should be used for component G?

• consumer

• decomposer

• producer

• soil

What do all biotic organisms require?

• energy

• grass

• land

• soil

  carbon dioxide in the air, air temperature

• number of animals in the area to complete oxygen and carbon dioxide

  exchange, soil temperature, air temperature, length of day

• number of decomposers in the soil, amount of water present, length

  of day, number of animals in the area to complete oxygen and carbon

  dioxide exchange
