Verified step by step guidance1
Understand the key terms in the question: 'population density,' 'carrying capacity,' 'age structure,' and 'population growth rate.' Each term has a specific meaning in biology.
Define 'population density': It refers to the number of individuals of a species within a specific unit area or volume. This is the term that directly matches the description in the question.
Define 'carrying capacity': This is the maximum number of individuals of a species that an environment can sustainably support, based on available resources.
Define 'age structure': This term describes the distribution of individuals of different ages within a population, which helps in understanding population dynamics but does not relate to individuals per unit area.
Define 'population growth rate': This refers to the rate at which the number of individuals in a population increases or decreases over time, which is different from the concept of density. Based on these definitions, the correct term is 'population density.'
