Комахи-запилювачі. Більшість квіткових рослин (близько 80%) залежать від комах, які запилюють квіти, забезпечуючи таким чином утворення насіння і плодів. Особливо велика роль як запилювачів рослин представників трьох рядів комах – перетинчастокрилих, двокрилих і метеликів. Комахи – шкідники рослин.

текст
Alexander Borodin was a genius in two fields:music and chemistry. Composing music was really a hobby for him, but he is considered one of the greatest Russian composers. His opera "Prince Igor" is considered to be one of the most important historical Russian operas.
He studied piano and cello as a youth, but got interested in chemistry after trying to make fireworks. He studied medicine, and became a surgeon for the Russian army.
Later, he became professor of chemisry at the Medico-Surgical Academy in St.Petersburg, and spent the rest of his life teaching stedents there. He loved teaching. He also spent a lot of his time doing scientific experiments.
He said in a letter thet writing music was just a hobby. Music filled his time when he was away from the chemistry lab or classroom. In fact he would often pause during discussions on music to check on experiments! He also said that he could only compose when he was too sick to give lectures.
