Question

In the models that describe population growth r stands for
A. Population density
B. A time interval
C. Total number of individuals in the population.
D. Growth rate

Answer 1

Hint: The exponential growth formula is used to express a function of exponential growth. To recall, exponential growth occurs when the growth rate of the value of a fine function is commensurable to the function’s current value, performing in its growth with time being an exponential function. In other words, when the growth of a function increases fleetly in relation to the increase in the total number, also it's exponential.

Complete step by step solution:
Population viscosity is the attention of individualities within a species in a specific geographic locale. Population viscosity data can be used to quantify demographic information and to assess connections with ecosystems, mortal health, and infrastructure.Population viscosity is the average number of individualities in a population per unit of area or volume. For illustration, a population of 100 insects that live in an area of 100 square cadence s has a viscosity of 1 nonentity per forecourt cadence.
 A time interval is the quantum of time between two given points in time. An illustration of this is" The time interval between three o'clock and fouro'clock is one hour. A longer length of time can be divided into a number of shorter ages of time, all of the same length. These are called time intervals. For illustration, say you wanted to measure the speed of an auto over a trip taking an hour. You could divide the hour up into time intervals of ten twinkles.
 Population size is the number of individualities in a population. Population viscosity is the average number of individualities per unit of area or volume. The pattern of distance of individualities in a population may be affected by the characteristics of a species or its terrain.
The rate, or speed, at which the number of organisms in a population increases. This can be calculated by dividing the change in the number of organisms from one point in time to another by the quantum of time in the interval between the points of time.
Option D is the correct answer.

Note:
To calculate the growth rate, take the current value and abate that from the former value. Next, divide this difference by the former value and multiply by 100 to get a chance representation of the rate of growth.
