The equation \(\frac{\Delta N_{n}}{\Delta N_{t}}\) represents which of the following
In a population unrestricted reproductive capacity is called as
Which one of the following ecosystem types has the highest annual net primary productivity?
They are found in the equatorial regions (rainfall exceeds 140 cm.). The warm humid climate supports broad leaved evergreen plants. Productivity is very high( 12000 k. cal/m2/ year). The vegetation show stratification into two or more well defined layers.
The formula for the line would best be written as
The maximum expansion rate of a population under the best conditions is referred to as _____. There are abundant resources that last forever and no limits on growth.
The mortality rate is a percentage of individuals that began a specific year alive but have passed away before the conclusion of the same year. Biotic potential of a species is influenced by the following length of reproductive life,how often reproduction occurs, how many progeny are created at each birth occurrence, what is the reproductive age, and how many live to actually reproduce.
A population of 600 that experiences 65 births and 5 deaths during a one-year period.If the population maintains the current growth pattern, a plot of its growth would resemble
If the reproductive rate is greater than zero (r > 0), then the population is growing exponentially.
A population of 500 that experiences 55 births and 5 deaths during a one-year period. What is the reproductive rate for the population during the one-year period?
The rate of growth, r, equals (55 births – 5 deaths)/ 500 per year, or 0.1/year.
All of the following population would likely result in a uniform dispersion pattern except:
The number of individuals per unit area or volume is known as . . .
The age-structure diagram of a country like Mexico, which has a high population growth rate, has the shape of__________.
The age structure of Mexico has a large fraction of individuals who are young and likely to reproduce in the near future. The overall shape is that of a pyramid.
