What is the basic component of natural environment?
Basic Component of Natural Environment:
The basic component of the natural environment consists of various elements that interact with each other to create a balanced ecosystem. These components include:

1. Atmosphere:
The atmosphere is the layer of gases surrounding the Earth. It plays a crucial role in regulating temperature, weather patterns, and the overall climate of the planet. The atmosphere also protects the Earth from harmful radiation and provides the necessary oxygen for living organisms.

2. Hydrosphere:
The hydrosphere comprises all the water on Earth, including oceans, rivers, lakes, and groundwater. Water is essential for all forms of life and plays a vital role in various natural processes such as the water cycle, erosion, and transportation of nutrients.

3. Lithosphere:
The lithosphere is the solid outer layer of the Earth, which includes the crust and upper mantle. It is home to various landforms such as mountains, plains, and valleys. The lithosphere provides habitats for plants, animals, and other organisms and also serves as a source of minerals and resources.

4. Biosphere:
The biosphere encompasses all living organisms on Earth and their interactions with the environment. It includes plants, animals, microorganisms, and ecosystems. The biosphere is responsible for maintaining the balance of nutrients, energy, and carbon cycles on the planet.
In conclusion, the natural environment is a complex system composed of interconnected components that work together to sustain life on Earth. Understanding and preserving these components are essential for the well-being of all living organisms and the health of the planet.

Similar UPSC Doubts

Many farmers use synthetic pesticides to kill infesting insects. The consumption of pesticides in some of the developed countries is touching 3000 grams/hectare. Unfortunately, there are reports that these compounds possess inherent toxicities that endanger the health of the farm operators, consumers and the environment. Synthetic pesticides are generally persistent in environment. Entering in food chain they destroy the microbial diversity and cause ecological imbalance. Their indiscriminate use has resulted in development of resistance among insects to insecticides, upsetting of balance in nature and resurgence of treated populations. Natural pest control using the botanical pesticides is safer to the user and the environment because they break down into harmless compounds within hours or days in the presence of sunlight. Plants with pesticidal properties have been in nature for millions of years without any ill or adverse effects on the ecosystem. They are easily decomposed by many microbes common in most soil. They help in the maintenance of biological diversity, of predators and the reduction of environmental contamination and human health hazards. Botanical pesticides formulated from plants are biodegradable and their use in crop protection is a practical sustainable alternative.On the basis of the above passage, the following assumptions have been made.1. Synthetic pesticides should never be used in modem agriculture.2. One of the aims of sustainable agriculture is to ensure minimal ecological imbalance.3.
