时差N小时 昆虫是怎样摄取水分的?(上)(在线收听) |
I was sitting on my Porsche yesterday, having a soda, and a wasp picked its head into the can and drink from my soda. 昨儿我坐在我的保时捷里,喝着汽水,一只黄蜂将头伸进了我的瓶子,喝起了我的汽水。 For the sugar I konw that's why I drink soda. 我知道我喝汽水是为了摄取糖分, But the Garmin wondering about how different insects drink. 但是Garmin好奇不同的昆虫是如何饮水的? I mean insects need water just like the rest of us. 我是说,昆虫也像我们一样需要水分。 You are right! Insects do need water. 没错!昆虫确实需要水分。 How they get their water depends a lot on their diets. 它们饮水很大程度上取决于他们的饮食习惯。 Herbivorous insects, those that feed on plants, get most of their water from their prey food because plants contain a lot of water. 对于那些以植物为食的食草性昆虫来说,大部分水分都是从食物中获取的,因为植物很有很多水分。 But carnivorous insects often have to get their water from somewhere other than their prey, and often they'll go to plants for their water too, drinking from fruit maybe. 但是对于食肉的昆虫来说,它们需要从其它地方获取水分,通常也是来自植物,或者水果。 |
