Which tree harvesting method promotes the growth of younger trees by selectively cutting mature trees over a period of 10 years?

Shelterwood cutting.

Explanation:

Shelterwood cutting is a technique employed in silvicultural processes that promotes the growth of younger trees by selectively cutting mature trees over a 10-year period.

In this technique is made the progression of cuttings that promotes the growth of seedlings resulting in the harvesting of mature trees and promotion of the growth of younger trees. Generally this technique is used in old forests where mature plants are causing shade of young plants. Generally young plants are long-lived and upon receiving light, after thinning the old plants, begin to develop properly and promises a longer duration of the forest.

i am going to guess that it is co2.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
