4. Water scarcity: Particularly in inland areas and during prolonged drought periods.

What is the definition of Environment?

From a scientific and ecological perspective, the environment encompasses all living and non-living things occurring naturally on Earth. It is the complex web of physical, chemical, and biotic factors that act upon an organism or an ecological community and ultimately determine its form and survival.

Components of the Environment

The environment consists of two main components:

1. Biotic Components: These are the living parts of the environment, including all organisms, from microscopic bacteria to large animals and plants. Biotic components are further categorised into producers (plants), consumers (animals), and decomposers (bacteria and fungi).
2. Abiotic Components: These are the non-living parts of the environment, including physical factors like soil, water, air, sunlight, temperature, and humidity, as well as chemical factors such as pH levels and nutrient availability.

The interactions between these components are complex and multifaceted. For instance, plants (biotic) use sunlight (abiotic) to produce food through photosynthesis while also influencing soil composition (abiotic) through root systems and leaf litter. Animals (biotic) depend on plants for food and shelter while also affecting plant distribution through activities like grazing and seed dispersal. These intricate relationships form the basis of ecosystems and drive the Earth's biogeochemical cycles.
