Question

Решите биологическую задачу Весной у березы сделав разрез в коре часто берут сладкий березовый сок 1 от восходящего или нисходящего тока берут этот сок? 2 что произойдет с березой если у нее взять очень много сока?

Answer 1

1.Березовый сок собирают из восходящего тока. Весной дерево проснулось, и корни начинают гнать сок вверх к ветвям. 
2.Дерево может погибнуть или через разрез заболеть, загнить, если потом надрез не обработать садовым варом, например. Поэтому же не берут сок у очень молодых растений. Они тоже без сока могут погибнуть.

Answer 2

Extracting Information from Search Results:

1. The first question asks whether the birch sap is taken from the ascending or descending flow. 2. The second question asks what will happen to the birch tree if a large amount of sap is taken from it.

Let's find the answers to these questions using search results.

Answer:

1. Birch sap is typically collected from the ascending flow in the tree. The sap rises from the roots to the branches during the spring season, carrying nutrients and water to support the growth of new leaves and buds. The process of sap flow in trees is known as transpiration. The sap is collected by tapping into the tree trunk and extracting the sap from the vessels in the xylem tissue. [[1]] [[2]]

2. If a large amount of sap is taken from a birch tree, it can have negative effects on the tree's health and growth. The sap contains essential nutrients and water that the tree needs for its metabolic processes and growth. Excessive sap extraction can lead to nutrient deficiency, dehydration, and stress for the tree. This can weaken the tree's overall health, making it more susceptible to diseases, pests, and other environmental stresses. It is important to practice responsible tapping and not overharvest the sap to ensure the tree's well-being. [[3]] [[4]]
