In some cases, polpulation density is measured in terms of biomass rather than in terms of numbers becouse ________________________.

In N = population density at time t, then population density at time +1 can be written as 
$$N_t+1 = N_1 + [(A +B) - (C + D)]$$
Select the correct option for A, B, C and D in the above equation. 

Which of the following factors has a negative effect on the population growth rate?

Which of the following is not an example of using relative density to measure population density in a certain area?

The given graph shows how much nitrate $$ \left( { NO }_{ \overline { 3 }  } \right)  $$ is exported from the continent towards the ocean by 16 major rivers in the world compared to the density of human populations living along those drainage basins (i.e., along these rivers). What interpretation can be drawn from this graph?

For which of the following cases, population density can be easily determined by utulising non-biological parameter?

A population with a larger proportion of older individuals than younger ones will likely to 

The density of a population in a given habitat during a given period, fluctuates due to changes in certain basic process On this basis, fill up boxes A and B the given flow chart with correct option. 

Which of the following is not a factor that would limit the growth of a population? 

Total number of individuals of a species per unit area and per unit time is called
