Managing Human Populations & Environmental Management

Flashcards covering key vocabulary and concepts related to human population dynamics and environmental management.

Population Density

The concentration of individuals in a specific location, calculated as the number of people divided by the area in km².

Factors Influencing Birth Rates

Factors that may include mortality rates, labor force demands, urbanization, marriage age, availability of family planning, and cultural beliefs.

Factors Influencing Death Rates

Biotic Components

Living components of an ecosystem that interact with organisms.

Abiotic Components

Non-living components of an ecosystem, such as water, temperature, and nutrients.

Photosynthesis

The process by which plants and other organisms convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen.

Chlorophyll

The green pigment in plants that absorbs light energy used for photosynthesis.

Dependency Ratio

A ratio that compares the number of dependents (aged 0-14 and 65+) to the working-age population (aged 15-64), indicating the pressure on workers.
