Multiple Choice

Which biome does the video clip most likely represent?

• Tundra

• Deciduous Forest

• Grassland

• Rainforest

Multiple Choice

Which BIOTIC factors are most likely found in the rainforest?

• rainfall and snakes

• heavy vegetation and tigers

• fertile soil and heavy rainfall

• snakes and migrating animals

Multiple Choice

Which biome does the video clip most likely represent?

• Desert

• Deciduous Forest

• Grassland

• Rainforest

Multiple Choice

Which set of ABIOTIC factors are present in a desert biome?

• reptiles and cacti

• very little rainfall and cacti

• sandy soil and very little rainfall

• fertile soil and heavy rainfall

Multiple Choice

Scientists observe that a desert ecosystem has experienced a decrease in plant biodiversity and an

increase in soil erosion. Which combination of abiotic and biotic factors best explains a decline in this

ecosystem’s health?

• Decreased precipitation leads to fewer plants, which reduces soil stability.

• Increased rainfall increases plant growth, which improves soil quality.

• Stable temperature with increased animal populations supports soil nutrients.

Multiple Choice

Which biome does the video clip most likely represent?

• Taiga

• Deciduous Forest

• Tundra

• Rainforest

Multiple Choice

Which biotic and abiotic factors are present in a Taiga biome?

• deciduous trees and heavy snow

• coniferous trees and heavy snow

• warm temperatures and coniferous trees

• cool climate and reptiles

Multiple Choice

Which biome does the video clip most likely represent?

• Taiga

• Deciduous Forest

• Tundra

• Rainforest

Multiple Choice

The white-tailed deer is found in the temperate forests of the United States and southern Canada. Its fur color changes from reddish-brown to gray-white, and the texture changes from a solid, thin, short hair undercoat to a long, thick, hollow hair. A scientist observes that this change occurs in regular intervals.

Which feature of temperate forests has led to these adaptations in white-tailed deer?

• large diversity of plants and grasses to eat

• hot summers and harsh, cold winters

• variations in precipitation rates

Multiple Choice

Which biome does the video clip most likely represent?

• Taiga

• Deciduous Forest

• Tundra

• Rainforest

Multiple Choice

The table below shows the average seasonal temperature and precipitation in a tundra ecosystem.

A tundra ecosystem is adapted to cold temperatures and low precipitation. Which seasonal weather

patterns would result in the least healthy ecosystem condition?

• a winter with -25°C average temperatures and 12 mm of precipitation

• a spring with -3°C average temperatures and 27 mm of precipitation

• a summer with 25°C average temperatures and 17 mm of precipitation

• a fall with 3°C average temperatures and 22 mm of precipitation
