question
How have savanna plants adapted to long periods of drought?
answer
Savanna plants have adapted to the long periods of drought in a variety of ways. Some savanna plants have the ability to store water. Other plants have long roots which allow them to reach the water table.
question
Savannas typically have more trees than grasslands.
answer
true
question
Compare and contrast savannas and grasslands.
answer
Savannas and grasslands are characterized by two seasons, maintained by fire, and have organisms that are drought resistant. Savannas have shrubs and isolated trees. While grasslands can have trees, their presence is rare and typically confined to rivers. Grasslands have a wide temperature range and receive a more even distribution of rainfall throughout the year. Savannas receive anywhere from 30 to 50 inches of precipitation annually while grasslands receive 10 to 30 inches.
question
Which of the following organisms is not found in savannas? a. cheetah b. pangolin c. porcupine d. hyena
answer
c. porcupine
question
Which of the following is not a savanna? a. Cerrado b. Pampas c. Llanos d. Serengeti
answer
b. Pampas
question
Which of the following plant adaptations aids grassland plants to recover from fires? a. spines b. water storage c. growth patterns d. bitter taste
answer
c. growth patterns
question
Some animals in grasslands can obtain water they need from plants.
answer
true
question
What characteristics does the serval have that make it well-suited to life on the savanna?
answer
The serval's long and powerful legs allow it to catch birds in midair. This ability is useful on the savanna where the trees are isolated and do not provide the birds with many areas of shelter away from the serval's reach. Servals have acute hearing, which allows them to track the movements of small animals underground. The savanna is home to many burrowing animals, so the ability to track them underground is particularly useful to the serval.
question
Why are burrowing animals and ground-dwelling birds common in grasslands?
answer
Burrowing animals and ground-dwelling birds are common in grasslands because there are very few trees in which birds and animals can take shelter. Burrowing also affords animals some protection from the fires and high temperatures that are common in grasslands during the dry season.
question
How do wildfires help maintain savannas and grasslands?
answer
Wildfires remove dead and dying growth. They also maintain the balance between larger plants and grasses. Larger plants, such as trees and shrubs, recover from fires less quickly than grasses. The removal of dead and dying growth allows new grasses to take their place.
