Answer:
1)Biodiversity of an area refers to the vast number of species of plants, animals and microorganisms existing in that area.
2)Fauna refers to animals, whereas flora refers to plants
3)Yes, I agree with the statement. Forests provide plant cover to check the flow of water. If forests are removed, then floods will occur.
4)False.
Endangered animals are those species whose numbers are diminishing at an alarming rate and face an immediate danger of extinction.
5)If all trees in a forest are cut, it will lead to erosion of soil.
6)Grazing by cattle should be controlled for forest conservation.
7)True.
Soil erosion is the removal of top layer of soil that is most fertile. If not checked, soil erosion ultimately leads to desertification.
8)The flora and fauna of a country are among the most important renewable natural resources.
9)Dinosaurs are extinct because no living member of this species is present on earth.
10)Wildlife conservation and forest conservation are closely related.

The answer is monogamy and polygyny.
Both terms have a Greek origin. By knowing their origin, it is easy to understand the terms.
Monogamy literally means one marriage, from the Greek <em>monos </em>- one, alone, and <em>gamos</em><em> </em>- marriage. So, in monogamy, one male breeds with only one female.
Polygyny literally means many wives, from the Greek <em>poly </em>- many, and <em>gyny</em><em> </em>- wife, woman. So, in polygyny, one male breeds with multiple females.
Plant life, especially the trees in the Rain forest absorb the carbon dioxide and produce oxygen so without them, there would be much more carbon dioxide.
In fact we believe that the oxygen in our atmosphere has origin in plant life! Specifically ocean plants. <span />
