Final answer:
Relative humidity and solar radiation have significant effects on the distribution of crops and animals. Relative humidity affects the growth and survival of crops, while solar radiation is crucial for photosynthesis. Different crops have varying humidity and sunlight requirements, leading to their distribution in different regions.
Step-by-step explanation:
Relative humidity and solar radiation have significant effects on the distribution of crops and animals.
Relative humidity, which refers to the amount of moisture in the air compared to the maximum amount the air could hold at a given temperature, influences the growth and survival of crops. Crops that require high humidity, such as rice and certain fruits, are typically found in regions with high relative humidity. On the other hand, crops that thrive in lower humidity conditions, such as wheat and corn, are commonly grown in areas with lower relative humidity.
Solar radiation, or sunlight, is crucial for photosynthesis in plants. It provides the energy needed for plants to convert carbon dioxide and water into glucose and oxygen. Different plants have varying light requirements, with some needing more sunlight and others being able to tolerate shade. As a result, crops that require more sunlight, such as tomatoes and peppers, are often grown in regions with higher solar radiation, while shade-tolerant crops like lettuce and spinach are suitable for areas with lower solar radiation.
