Question

В лесном сообществе популяции дуба и березы представлены только плодоносящими деревьями (молодые особи отсутствуют). Можно ли ожидать, что оба эти вида выпадут из состава сообщества после естественного старения или отмирания верхнего яруса деревьев? ( ОТВЕТЬТЕ СКОРЕЕ ДАЮ 30 БАЛЛОВ )​

Answer 2

В)береза сохранится в составе сообщества.

Объяснение:

Береза сохранится в составе сообщества: её плоды- крылатки- легкие и могут быть занесены с ближайших территорий. Выпадение из сообщества грозит дубу, т.к. его плоды тяжелы и не могут быть занесены ветром. Дуб может сохранится только в случае рубки при условии совпадения года рубки с годом плодоношения дуба.

Answer 3

Can we expect oak and birch trees to disappear from the forest community after natural aging or the death of the upper tree layer?

In a forest community where only fruit-bearing trees of oak and birch are present and young individuals are absent, it is possible that both of these species may eventually be lost from the community after natural aging or the death of the upper tree layer. However, it is important to note that the long-term dynamics of forest communities are influenced by various factors, and the ultimate outcome may depend on specific ecological conditions.

The absence of young individuals in the community suggests a lack of successful reproduction and recruitment for oak and birch trees. This could be due to various reasons, such as limited availability of suitable germination sites, competition from other species, or changes in environmental conditions. Without successful reproduction and recruitment, the population of oak and birch trees may decline over time.

Additionally, the aging and death of the upper tree layer can have significant impacts on the structure and composition of the forest community. When the dominant trees in the upper layer die, it creates gaps in the canopy that can allow for the establishment and growth of new individuals from other species. If oak and birch trees are unable to successfully regenerate and fill these gaps, they may be gradually replaced by other species that are better adapted to the changing conditions.

It is worth mentioning that the specific response of oak and birch trees to aging and the death of the upper tree layer can vary depending on the ecological context and the interactions with other species in the community. Therefore, it is difficult to make a definitive prediction without considering the specific dynamics of the forest community in question.
