Ответы

Автор ответа: Hjffjrdiijjd

Несмотря на свои микроскопические размеры, фитопланктон, который плавает вповерхностных водах, составляет около 90% массы океанских растений. Оставшиеся 10%приходятся на долю гораздо более крупных неплавучих водорослей и еще одного плавучегорастения, способного расти в морской воде, - морской травы. Морские водоросли различаются поцвету. Бурые и большинство зеленых водорослей нуждаются в прямых солнечных лучах и растут на мелководье. Многим видам красных и нескольким видам зеленых водорослей нужно небольшое количество света, и потому их можно обнаружить на более значительных глубинах или в подводных пещерах. Подобно растениям суши, водоросли часто бывают сезонными, обильно растут весной и летом. и увядают зимой. Многие водоросли состоят из желеобразных тканей, а некоторые имеют известковый скелет и напоминают камни.
