Question

From red apples and yellow lemons to blueberries and green melons, fruit comes in many different colors. 1..

According to Lu Wei from the Chinese Academy of Sciences, fruit colors actually come from their different pigments（色素）.These pigments appear differently, depending on the fruit's environment. 2..

To find out how environment influences fruit colors, Chinese scientists studied more than 280 different fruit colors. They found that red fruit usually grow in cooler places. And instead of just growing in one place, you can find them growing in many places around the world. 3.. These fruits grow a lot in just one certain area. The scientists also found that the closer the fruit is to the equator（赤道）, the darker its color will be.

4.. Animals eat fruit and drop the seeds（種子）in other places later. This helps the fruit spread and grow in different places. Therefore, in order to attract animals, some fruit develop colors that are easy for animals to see.

However, animals see colors in a different way.5.. For example, birds can see red more easily than humans can. Therefore, there is more red fruit in areas where birds live. The lemurs（狐猴）of Madagascar are red-green color-blind. Many yellow fruit can be found there, as they can easily see this color.
