Question

Geometric representation of age structure is a characteristic of
A. Biotic community
B. Population
C. Ecosystem
D. Landscape

Answer 1

Hint: The term population is defined as a number of individuals in a specified place. The population highly depends on the geographical factors present in that particular area. Mortality, natality, as well as age distribution, are some of the attributes of the population. This is represented as a geometrical method in the form of the age pyramid. The x-axis on the graph represents the size of the population where the y-axis represents the age groups.

Complete answer:
Option – A – Biotic Community
A biotic community, also recognized as abiota or 'biocoenosis', is the group of organisms that live together and interact with each other within a specified environment.
Option – B – Population
In biological terms, the population describes all the organisms of the same group or species who live in a particular geographical area and are capable of interbreeding.
Option – C - Ecosystem
An ecosystem can be defined as a community of living organisms in conjunction with the nonliving or abiotic components of their environment, interacting as a system. These biotic along with abiotic components are linked together through nutrient cycles as well as energy flows.
Option – D – Landscape
The term landscape is used to refer to the visible features of an area of land, its landforms, as well as how they integrate with natural or man-made features.

So, the correct answer is option B - Population.

Note: In most populations, individuals are of different ages. The actual proportion of individuals in each age group is called the age structure of that particular number of population.
