Grassland, Desert, and Tundra
Biomes
1. What is another word for grassland?
• Savanna
Savanna
2. Are savannas temperate or tropical
biomes?
Savanna Biomes areTropical.
3. Grasslands, deserts, and tundra
receive (high/low) amounts of
precipitation.
• Grasslands, deserts, and tundra receive low
amounts of precipitation.
4. Name three animals that live on a
savanna.
•
•
•
•
Elephants
Gazelles
Giraffes
Black Rhinos
5. Look at the graph on page 165.
What months would be part of the
“wet season” on the savanna?
• November, December, March, April, and May
6. What is important about the wet
season?
• This is the only time that plants can grow.
7. What happens to the plants on the
savanna during the dry season
• Plants lose their leaves,
and die down to the
ground. Many plants have
large horizontal root
systems so that they can
pull water from many
directions when it does
return.
8. Why do some plants on the savanna
have thorns?
• To keep hungry herbivores away.
9. What season would most animals
give birth on the savanna?
• Only during the rainy season, when food is
easy to find. Their young are more likely to
survive.
10. Name three animals you would
find on a savanna?
• This is a repeat.
Temperate Grasslands
11. Name four areas on the globe that
support temperate grasslands?
• The prairies of North
Amierica

• The veldt in South
Africa

consists mainly of what two types of
plants?

14. Grasslands are highly productive
because of their_________ soil.

expect to find in a chaparral?
• Low Lying, evergreen shrubs and small trees
22. What types of leaves do these
plants have?
• Small, leathery leaves
23. Why is a fire an advantage for
plants of the chaparral?
• Natural fires destroy trees that compete with
chaparral plants for light and space
24. What is an adaptation for animals
living in the chaparral?
• Camouflage
25. What types of animals live in the
chaparral?
• Quail, lizards, chipmunks and mule deer.
• All have brownish-gray coloring that lets them
move without being noticed.
26. What is the main threat to the
chaparral biomes?
• Human Development
27. How does camouflage help
chaparral animals?
• Lets them blend into their environment.
Desert
28. The driest places on earth belong
to what type of biome?
• THE DESERT

desert vary so much in a 24 hour period?
• There is very little insulating moisture in

• Mountain Ranges
31. What is a succulent?
• Plants with thick, fleshy stems and leaves that

32. Describe a leaf on a cactus.
• They have a waxy coating that prevents water

• Breed during the summer
43. Why do animals lose their brown
hair on the tundra?
• They have white fur that will camouflage them
in the winter snow.
44. The tundra is one of the most
_______ biomes on earth.
• The tundra is one of the most FRAGILE biomes
on the earth. The food chains are very simple,
so they are easy to disrupt.
45. What important resource can be
found on the tundra?
• OIL
46. What is the main threat to the tundra?
• Oil exploration, extraction, and transport has
disrupted the tundra
• Pollution caused by spills or leaks has also
poisoned water sources.
