Answer: Emigration or increase in death rate Explanation: Many factors can modify the animal population in a specific area.Amphibian populations are affected mostly by changes in temperatures, altered dry season rainfall, and modified leaf litter depth.Considering the options provided, only emigration and an increase in death rate could explain the decrease of the frog population. Immigration ...
A population of frogs in a pond began with 67 individuals. Over one year, the population changed to 53. Which are two possible reasons for the change within the frog population? emigration or increase in death rate emigration or increase in birth rate immigration or decrease in death rate immigration or increase in birth rate
Birth rate is the ratio between births and individuals in a specified population and time often expressed as number of live births per hundred or per thousand population per year. It is called also natality. Birth Rate is the term used to define the number of babies born every year per 1000 people in a population.
In a pond there were 200 frogs 40 more were born in the year calculate the birth rate of the population 11116157
Through reproduction, 25 new lotus plants were added in one year while 8 plants died. The birth and death rates for the lotus population respectively are ____ and ____ individuals per lotus per year.
A population can measure the number of species that live in a particular area, and the statistical report of the population is called demography. We can measure the population according to their size, number of individuals, and density.
Find the frequency of heterozygotes in a population of frogs in a pond, where 4 percent of the population shows recessive phenotype.
It all begins with frogs having maximum number of the individuals that will helps in sustain the environmental features without using or destroying. Therefore, the size of a frog population in a pond remains fairly constant over a period of several years because of Environmental carrying condition.
The birth rate of the frog in the bond is 0.5 per year. Option B Explanation: From the question, we can understand that, In last year there are 400 frogs and in the next year 200 frogs were added through reproduction. And the total frogs in the pond is 600 frogs. We need to find the birth rate of the frogs. Then, the birth rate is defined as per the question, is the ratio of the total no. of ...
The birth rate is the number of live births per 1000 people while the death rate is the number of deaths per 1000 people. These are the natural causes of population change.
