Basics & Biomes
This is the main difference between grasslands and savannas.
What is the presence of scattered trees in savannas?
Name one tree commonly found in savannas.
What is the baobab, acacia, eucalyptus, or candelabra tree?
Tourists in the savanna can harm ecosystems by doing this.
What is trampling vegetation and scaring animals away?
Fires in savannas are usually caused by this natural phenomenon.
What is lightning?
Rotational grazing helps grasslands recover because it allows this to happen.
What is the land restoring itself/vegetation regrowing?
Grasslands are known for this type of soil, which makes them great for agriculture.
What is fertile soil from decaying roots
Elephants and giraffes are found in this biome.
What is the savanna?
Overgrazing leads to this type of soil degradation.
What is soil erosion?
Natural fires are actually beneficial because they prevent this problem.
What is excess tree growth?
Overgrazing makes ecosystems vulnerable to this process, where fertile land turns into desert.
What is desertification?
This biome is located in tropical or subtropical regions with a long dry season and short wet season.
What is the savanna?
Bison and prairie chickens are found in this biome.
What is the grassland?
Humans often clear savannas to grow crops such as these two.
What are maize and soy?
Climate change increases these two conditions that threaten savannas.
What are drought and desertification?
Planting drought-resistant vegetation is one way to adapt to this global issue.
What is climate change?
This grassland type is found in regions with moderate rainfall and few trees.
What is the temperate grassland?
These large herbivores were nearly hunted to extinction in temperate grasslands.
What are bison (buffalo)?
Poaching savanna animals often leads to this major ecological problem.
What is loss of biodiversity/extinction?
Increased CO₂ levels favor the growth of these plants over grasses.
What are woody plants/trees?
These three strategies can restore overgrazed land.
What are rotational grazing, matching land capacity to animals, and planting native species?
This savanna covers about 10 million square miles in Africa.
What is the African savanna?
This animal is critical for seed dispersal in savannas but is threatened by poaching.
What is the elephant?
In temperate grasslands, humans almost drove this species extinct by hunting for meat and fur.
What is the bison?
This major climate pattern change reduces precipitation and harms vegetation.
What is altered rainfall from global warming?
Preventing illegal hunting of elephants is important because they are key to this ecological process.
What is seed dispersal?
