BIOXII13: ORGANISMS AND POPULATION
344383
If in a pond, there are 20 lotus plants of last year and through reproduction 8 new plants are added. Then, the birth rate is
1 0.8 offspring lotus per year
2 0.4 offspring lotus per year
3 0.2 offspring lotus per year
4 0.6 offspring lotus per year
Explanation:
Rate \(=\) Change in population/Orignal population \(=28-20 / 40=8 / 20=0.4=820=0.4\) offspring lotus per year.

The representation of age pyramid for human population given here, shows
1 Declining population
2 Stable population
3 Increasing population
4 Fluctuating population
Explanation:
As the base of the pyramid is denoted by pre reproductive individuals the number of pre reproductive individuals is same hence not undergoing any changes it is a stable pyramid.
