An ecological pyramid is a graphical representation designed to show the biomass or bio productivity at each trophic level in a given ecosystem. Biomass pyramids show how much biomass is present in the organisms at each trophic level, while productivity pyramids show the procreation or turnover in biomass.
Answer:
The benefits of conserving biodiversity are numerous. A large proportion of South Africa's population are directly dependent upon biological resources for subsistence purposes, including the gathering, harvesting or hunting of animals and plants for food, medicine, shelter, fuel, building materials, and trade.
Explanation:
The relaxed form of DNA in a cell's nucleus is called chromatin.
<h3>CHROMATIN:</h3>
- Chromatin is a complex of DNA and histone proteins within the cell's nucleus. The DNA is too long to fit into the cell's nucleus, hence, is coiled around proteins called histones.
- This complex forms the structure called chromatin, which then condenses during the prophase stage of cell division to form a more compact structure called chromosome.
Therefore, it can be said that the relaxed or uncondensed form of DNA in the nucleus of a cell is called chromatin.

In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. ... However, because hydrogen bonds are weaker than covalent bonds, in liquid water they form, break, and reform easily. Thus, the exact number of hydrogen bonds formed per molecule varies.
