The number of organisms of the same species living within the total area of their entire habitats is best known as...
A. Population size
B. Ecological desity
C. Crude density
D. None of the above
This is a really nice webpage:

it tells you what Population is in the first few lines.
To determine the correct answer, we need to understand the definitions of each option and what they represent in ecology:
A. Population Size: This term refers to the total number of individuals of the same species living in a given area or habitat.
B. Ecological Density: This concept encompasses the number of individuals of the same species per unit of available living space or habitat. It takes into account the spatial distribution and behavior of the species in relation to their environment.
C. Crude Density: Crude density, also known as arithmetic density, is a measure of the population size per unit area without considering any specific environmental factors or habitat characteristics.
To find the best answer, we need to identify the term that refers to the number of organisms of the same species living within the total area of their entire habitats. Based on this definition, the most appropriate choice is A. Population Size. It accurately represents the total number of individuals of the same species in their respective habitats.
