Biological factors (reproductive rate, survival rate, life expectancy), environmental factors (resource availability, climate conditions, natural disasters), and social factors (migration, human activities, social structure) collectively influence population size, demographics, and dynamics.

Graphic Organizer: Factors Affecting Population Size

Biological Factors:

Reproductive Rate: The speed at which individuals reproduce influences population growth.

Survival Rate: The ability of individuals to survive impacts population size.

Life Expectancy: The average lifespan of individuals affects the population's overall demographic structure.

Environmental Factors:

Resource Availability: The abundance or scarcity of resources influences population sustainability.

Climate Conditions: Environmental factors, such as temperature and precipitation, impact habitat suitability.

Natural Disasters: Events like floods or droughts can disrupt ecosystems, affecting population dynamics.

Social Factors:

Migration: Movement of individuals into or out of a population alters its size.

Human Activities: Anthropogenic actions, like deforestation or urbanization, can impact habitats.

Social Structure: The organization of individuals within a population influences behavior and interactions.

The question probable may be:

What are the three major factors identified in the graphic organizer that significantly influence population size, and how do each of these factors contribute to population dynamics?
