Proportion of reproductive age group is higher than pre-reproductive groups in

In the following equation of Verhulst - Pearl logistic growth, the letter $\text{'}\mathrm{r}\text{'}$ denotes ___ .

$\frac{\mathrm{dN}}{\mathrm{dt}}=\mathrm{rN}\left(\frac{\mathrm{K}-\mathrm{N}}{\mathrm{K}}\right)$

Read the following data carefully

Imagine the lion population grows logistically where the carrying capacity is $800.$ Then the per capita birth rate$\left(\mathrm{b}\right)$, per capita death rate$\left(\mathrm{d}\right)$, intrinsic rate of natural increase$\left(\mathrm{r}\right)$, increase or decrease in population during the unit time period $\left(\frac{dN}{dt}\right)$ are respectively

In the graph below, where $\mathrm{N}$ is population size and $\mathrm{t}$ is time, $\mathrm{M}$ represents

The shape of the pyramids reflects the growth status of the population. Identify the type of age pyramid represented below for human population.
