Question

В сосновом лесу нижние ветки сосны отмирают, у сосны, которая не в лесу, есть отмершие частички и наверху и снизу. Почему? Во время сильного ветра ели вырываются с корнями, а у сосен обламываются верхушки. Почему?

Answer 1

1 сосна светолюбива, на нижние ветки свет не попадает и они начинают отмирать.

2 У ели большая крона и слабые корни,растущие не вглубь,а по земле.А у сосны крепкие и высокие корни.

Understanding Pine Trees' Branches and Tops

When lower branches of pine trees in a forest die off and the tops of pine trees outside the forest break off during strong winds, it can be attributed to several factors.

Differences in Growth Conditions: The growth conditions for pine trees in a forest and those outside the forest are quite different. Trees in a forest often compete for sunlight, nutrients, and space, which can lead to the lower branches dying off as they are shaded out by the upper canopy On the other hand, trees outside the forest may have more access to sunlight and space, allowing for healthier growth throughout the tree, including the top.

Impact of Wind: During strong winds, the impact on trees can vary based on their location and environment. Trees in a forest may experience a different distribution of force due to the surrounding trees, which can lead to the breaking of the tops. Meanwhile, trees outside the forest may experience more uniform force distribution, leading to a different pattern of damage.

Tree Stress and Resilience: The stress on trees in a forest due to competition and limited resources can weaken their overall resilience, making them more susceptible to damage during strong winds. Conversely, trees outside the forest may have better access to resources and may be more resilient to wind damage.

Conclusion: In summary, the differences in growth conditions, the impact of wind, and the overall stress and resilience of the trees can explain the observed phenomena with the pine trees in the forest and outside the forest.
