Chapter 12, Problem 1TYC

To determine

To enlist: The minimum two reasons that the natural primary forests contain more biodiversity than the single-species forestry plantations.

Answer to Problem 1TYC

The non-interference of humans in the old forests, diversity of trees in old forests, and the plantation of one type of trees in forests are the reasons for the more biodiversity in old primary forests.

Explanation of Solution

The forests are the ecosystems that are the home for the millions of organisms. The forests are the self-sustaining ecosystem that flourishes and expand on their own. The forests are the part of the biodiversity as being a part and also act as a habitat place for all other species residing in the forests.

The three reasons for the statement that the natural primary forests contain more biodiversity than the single-species forestry plantations are as follows:

(1) The old $-$ growth primary forests are the forests that have been not influenced by the human activities for hundreds or thousands of years and have grown naturally. This has resulted in diversification and accumulation of species of animals and plants and other organisms. This has lead to the richness of biodiversity.

(2) The diversity in the types of trees in the old primary forests has been proved to be the homes for the various other organisms and thus the old primary forests provide more habitat regions of the animals.

(3) The single species plants forests are the forests made for the plantation of the economically profitable trees. The interaction of animals or other organisms with these plants will be less than it was in the old primary forests. So, this will reduce the biodiversity of these types of forests.
