Final answer:
Domesticated plants rye and wheat are from temperate climates, whereas yam and manioc are from tropical regions. Wheat was domesticated in the Fertile Crescent, and yam originates from West Africa, indicating the adaptation of these plants to their respective climates. The answer is option D.
Step-by-step explanation:
Domesticated plants such as rye and wheat come from temperate zone wild ancestors, while yam and manioc come from warmer, more tropical regions. Wheat was domesticated around twelve thousand years ago in the Fertile Crescent, which is known as the birthplace of agriculture. This region covers parts of the modern Middle East. This early form of agriculture included the cultivation of wheat and barley, alongside other crops such as peas, lentils, and olives.
On the other hand, crops like yam and manioc were domesticated in different parts of the world with warmer climates. Yam was domesticated in the regions of West Africa, like the Niger River bend, while manioc, also known as cassava, originally comes from South America. These crops were suitable for cultivation in tropical regions due to their ability to thrive in warmer and more humid environments.
Rice is another important crop that was originally domesticated in Asia and requires warm, moist conditions for growth, making it a staple in tropical and warm temperate habitats. Unlike wheat, which is well-suited to temperate climates, rice is primely associated with the tropical regions from where it originates.
