Fires in grasslands prevent
plants of all kinds
runners that feed the grass
migrating animals that eat the grass
scrub brush that competes with grass
A vertical feeding pattern is
a separation of animal habitats
the amount of food predators eat
a way for animals to avoid competition
the time of day animals eat
The main difference between deserts and grasslands is
vegetation density
grass fire frequency
annual rainfall
animal population
The wind is helpful to prairie grasses because it helps them
reproduce
carry away dead grass
keep their leaves dry
start grass fires
The major factor keeping forests from growing into grassland areas is
grazing
rainfall
forest fires
grass fires
One way of telling you are in a savanna is by the
short, fine-bladed grasses
presence of animals
forest of trees
tall, tufted, coarse-bladed grasses
Soil aeration is caused by
burrowing animals
fertilizers
tree roots
grazing animals
An adaptation that helps trees survive in dry grasslands is
growing rapidly
being-drought resistant
having most of their mass below ground
having shallow roots
Most grass of the prairies
grow in tufts
are bunchgrasses
are sod-forming grasses
grow in clumps
Savannas do NOT exist in the United States because
they are only in Africa
they exist only in tropic or subtropical areas
they have been destroyed by overgrazing
it is too dry
