Biomes unit test

  • Of the major earth biomes (tundra, grassland, desert, temperate deciduous forest, boreal forest/taiga, and tropical rainforest), which is not found in the United States (counting Alaska and Hawaii?)

  • Tundra

  • Taiga

  • Grassland

  • Temperate Deciduous Forest

  • Desert

  • Tropical Rainforest

  • All of these can be found somewhere in the U.S.

This process demonstrates the process where nutrients from the ocean floor are carried up to the surface where they can be used by producers. This process is known as

a. Phototropism b. Downgrading c. Upwelling


Biomes unit test

Plants growing near the ground in tropical rainforests often have dark green leaves or leaves that are very large. What is the benefit of these adaptations?

They are able to gather more of the sunlight that trickles to the forest floor. Remember, only 2% of the sunlight makes it to the forest floor in the TRF.


Biomes unit test

Describe how the type of flood seen in this deserted area of Nevada differs from the types of flood that occur in rivers like the Ogeechee.

“Flash floods” like this can appear seemingly out of nowhere as a result of precipitation many miles away.


Biomes unit test

Most marine life is found in shallow areas near the coast. What factor makes these zones more favorable for life?

These regions have more nutrients from rivers and from upwelling; the algae and marine plants need these nutrients and must be within the sunlight zone for photosynthesis.


Biomes unit test

What is being demonstrated in this graph?

The relationship between annual temperature and precipitation and the type of biome that develops.


Biomes unit test

Poor farmers in areas near tropical rainforests frequently clear a couple of acres of forest in order to grow food to feed their families. Unfortunately, they are able to grow food only for 2-3 years before the land no longer produces. What is the best explanation for the short period of soil viability ?

The soil of the rainforest is generally very thin and nutrient poor to begin with. The nutrients in the soil would be used up very quickly by the farmer’s crops leaving the soil unable to support plant growth.


Biomes unit test

What does the shape of the lower trunks of these trees most likely indicate about the tree itself?

The root system for the tree is very shallow or the ground may be very soft. This shape trunk provides the tree with extra support or stability.
