Question

Answer

Attributes of a Population

A population refers to a group of individuals of the same species living in a particular area at a specific time. The attributes of a population are the characteristics or features that describe the population. The following are the attributes of a population:

1. Mortality: Mortality refers to the death rate of individuals in a population. It is an important attribute because it determines the size of the population.

2. Sex Ratio: Sex ratio refers to the proportion of males to females in a population. It is an essential attribute because it affects the reproductive potential of the population.

3. Natality: Natality refers to the birth rate of individuals in a population. It is an important attribute because it determines the growth rate of the population.

Why Species Interaction is not an Attribute of a Population

Species interaction refers to the interactions between different species in an ecosystem. It is not an attribute of a population because it involves interactions between populations rather than characteristics of a single population. Species interaction is an important aspect of ecology, but it is not a feature that can be used to describe a single population.

Answer

Species interaction refers to direct and indirect interrelationship between different organisms, while on the other hand population attributes include population size, population density, population spacing, and age structure. Mortality is the ratio of deaths in an area to the population of that area; expressed per 1000 per year.
Sex ratio is the ratio of males to females in a population.
Natality is defined as the birth rate which is the total number of live births per 1000 in a given population during a given time period or a year

Answer

Species interation is not considered as a factor affecting the population. the main 4 factors are namely, natality, mortality, immigration,emigration

Answer

Natality, Mortality and sex ratio are attributes of a population. Species interaction can be inter or intraspecific, where population forms the part of the species confined by geographical or other environmental barriers.

Answer

Option B is correct

Answer

Species interact is not an attribute to population.because , mortality,natality,sex ratio is used to calculate the population rate.but not a species interaction.sp. interaction is a just interaction of sp. to it's sorrounding environment.

Answer

Species interaction doesn't effect population whereas mortality (death rate), natality (birth  rate), sex ratio does therefore it is not an attribute of a population
