Dominant vegetation and animals in grasslands are: Option
1: Dominant vegetation in grasslands is grass, and animals include zebras, lions, and gazelles. Option
2: Dominant vegetation in grasslands is cacti, and animals include kangaroos and koalas. Option
3: Dominant vegetation in grasslands is shrubs, and animals include elephants and tigers. Option
4: Dominant vegetation in grasslands is bamboo, and animals include pandas and snow leopards.
The Correct Answer and Explanation is :
The correct answer is Option 1: Dominant vegetation in grasslands is grass, and animals include zebras, lions, and gazelles.
Explanation:
Grasslands are a type of biome characterized by vast open spaces dominated primarily by grasses and few trees. They are found on every continent except Antarctica and are known by various names, such as prairies in North America, savannas in Africa, and steppes in Asia. The dominant vegetation in these areas is indeed grass, which is well-adapted to the often dry conditions and periodic fires that can occur in these ecosystems. Grasses have deep root systems that help them absorb water efficiently and withstand droughts, making them a resilient choice of vegetation for grasslands.
The animal species commonly found in grasslands have adapted to this environment as well. For instance, zebras and gazelles are both herbivores that graze on the abundant grass, while lions, as apex predators, prey on these herbivores. This predator-prey relationship is crucial in maintaining the ecological balance within the grassland ecosystem.
In contrast, the other options provided refer to different biomes:
- Option 2 mentions cacti, which are typically found in deserts, not grasslands. Animals like kangaroos and koalas are native to Australia and are associated with more forested or scrubland environments.
- Option 3 includes shrubs and animals such as elephants and tigers, which are more characteristic of savannas or forested areas, rather than typical grassland ecosystems.
- Option 4 refers to bamboo and animals like pandas and snow leopards, which are associated with temperate forests and mountainous regions, respectively.
In summary, grasslands are defined by their grass-dominant vegetation and specific animal communities adapted to this unique environment, making Option 1 the correct choice.
