Which of the following organisms is commonly found in grassland ecosystems?

• A. Cheetah
• B. Rhea
• C. Pangolin
• D. Hyena

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the characteristics of a grassland ecosystem. Grasslands are open areas dominated by grasses, with few trees, and are typically found in regions with moderate rainfall. They support a variety of herbivores and carnivores adapted to this environment.
2. Step 2: Analyze the organisms listed in the question. Consider their natural habitats and ecological roles. For example, cheetahs are fast predators often found in savannas, which are a type of grassland. Rheas are large flightless birds native to South American grasslands. Pangolins are insectivorous mammals typically found in forests and savannas, not exclusively grasslands. Hyenas are scavengers and predators commonly found in African savannas.
3. Step 3: Narrow down the options based on their primary association with grassland ecosystems. Focus on organisms that are specifically adapted to grasslands rather than other ecosystems like forests or deserts.
4. Step 4: Consider the geographical context of grasslands. For example, South American grasslands (pampas) are home to rheas, while African savannas are home to cheetahs and hyenas. Pangolins are less commonly associated with grasslands.
5. Step 5: Based on the analysis, identify the organism most commonly found in grassland ecosystems. Ensure the choice aligns with the ecological and geographical context provided in the question.
