Population refers to the total number of individuals or organisms of a particular species that inhabit a specific area or region at a given time. It is often used in the context of human populations, but can apply to any species in a defined habitat.

(1bi)
Size:
Population size is the total number of people living in a particular area at a given time. It reflects the scale of human presence and is influenced by birth rates, death rates, immigration, and emigration. Knowing population size helps governments plan for resources, infrastructure, and services such as schools, hospitals, and housing. For example, a large population size may increase demand for jobs and social amenities, while a small population may limit economic growth. Population size is usually measured through a census.

(1bii)
Density:
Population density is the average number of people living per unit of land area, often expressed as persons per square kilometer. It shows how crowded or spacious an area is. High density often occurs in urban centers, leading to challenges like congestion and pressure on resources, while low density is common in rural or harsh environments. Density is influenced by physical factors (water availability, climate, terrain) and human factors (economic opportunities, infrastructure). Understanding density helps in urban planning and resource management.

(1biii)
Quality:
Population quality refers to the overall wellbeing and capabilities of the people, including health, education, and living standards. A high-quality population is generally healthier, better educated, and more productive, which promotes economic development. Factors such as access to healthcare, nutrition, literacy, and social equality determine population quality. Improving quality involves investments in education, health services, and social welfare to enhance human potential and national progress.

(4b)
(i) Broad Leaves with Drip Tips: Leaves are broad to capture maximum sunlight and have drip tips to shed excess rainwater, preventing fungal growth.
(ii) Tall Trees with Buttress Roots: Trees grow tall to compete for sunlight in dense forests; buttress roots provide stability in shallow, nutrient-poor soils.
(iii) Evergreen Nature: Many trees retain leaves year-round to maximize photosynthesis in the consistently warm and wet climate.

(4c)
(i) Deforestation due to Logging and Farming: Forests are cleared extensively for timber and to create farmland, which reduces tree cover and biodiversity. This large-scale clearing disrupts ecosystems and limits the forest’s ability to regenerate naturally. The continuous removal of trees also leads to soil erosion and loss of nutrients necessary for plant growth.

(ii) Climate Change and Drought: Irregular rainfall and prolonged dry seasons cause water stress to trees, reducing their growth and making them more vulnerable to pests and diseases. These changing climate patterns also lead to forest degradation and loss of vegetation cover. Additionally, extreme weather events like floods and droughts further damage forest ecosystems and hinder recovery.

(iii) Urbanization and Industrialization: Rapid growth of cities and industries results in the clearing of forests for housing, roads, and factories, destroying natural habitats.
