4. ЗАДАЧИ НА СУКЦЕССИЮ

Под пологом участка елового леса, расположенного по берегу небольшой лесной реки, росли кислица, майник и седмичник. После того как речка ниже по течению была перепружена плотиной для строительства колхозного пруда, на этом участке началось изменение состава растительности: здесь появились черника и зелёный мох, мох кукушкин лён, взрослые ели начали чахнуть, а проростки погибали на ранних стадиях развития. Затем кукушкин лён был вытеснен сфагнумом. Почему произошли эти изменения?
