Covalent bonds is the answer
Establishing just one tree species can impair soil fertility and prevent other species from being established.
We can arrive at this answer because:
- Ecological succession is the term that refers to the establishment and development of plant species in areas that were devastated until that area presents a large vegetative population when it reaches climax.
- During the establishment of ecological succession, the must be a great diversity of plants, allowing for harmony and balance between the species and the environment.
- When ecological succession is done with only one species, this balance is impaired, as well as ecological succession.
This is because a single tree species can hide soil fertility and make it unsuitable for planting any other species. In addition, the genetic unity among plants makes it easier to develop pests and diseases that can devastate the region.

DRIs is the general term for a set of reference values or guidelines that are used to plan and asses nutrient intakes of healthy people. These values which vary by age and gender include:
- Recommended Dietary allowance (RDA): average daily level of intake sufficient to meet nutrient requirements of about 97 - 98% of healthy people.
-Adequate intake (AI): established when evidence is not sufficient to develop an RDA and is set at a level assumed to ensure nutritional adequacy.
- Tolerable Upper Intake (UL): Maximum daily intake unlikely to cause adverse health effects.
DRIs are not necessarily found on labels because there is no law requiring that they must be placed there.
