Biotic and Abiotic Resources

Biotic and Abiotic Resources

Natural resources are broadly classified into biotic (living) and abiotic (non-living) resources. Both are essential for the survival of life and the balance of ecosystems.

1. Biotic Resources

Biotic resources are derived from living organisms such as plants (forest, grassland, aquatic plant), animals (wildlife, aquatic plant) and microorganisms. They are renewable in nature (can reproduce and regenerate), though excessive exploitation may make them scarce.

Types of Biotic Resources:

  1. Flora (Plant Resources) Examples: Forests, crops, medicinal plants, fruits and vegetables.  Importance: Provide food, oxygen, timber, fiber, and medicines.

  2. Fauna (Animal Resources) Examples: Livestock (cows, goats, sheep), wild animals, fishes, birds, and insects. Importance: Provide meat, milk, leather, wool, pollination and maintain ecological balance.

  3. Microorganisms Examples: Bacteria, fungi, algae and protozoa. Importance: Help in decomposition, nitrogen fixation, fermentation and biotechnology.

2. Abiotic Resources

Abiotic resources are derived from non-living components of nature such as air, water, soil, sunlight and minerals. These are non-renewable like minerals and fossil fuels (metal, crude oil, coal) and renewable like water, sunlight (solar energy) etc.

Types and Classification of Abiotic Resources:

  1. Atmospheric Resources Examples: Air, sunlight, wind. Importance: Provide oxygen for respiration, carbon dioxide for photosynthesis, energy from the sun and wind.

  2. Hydrospheric Resources Examples: Rivers, lakes, well, oceans, groundwater.       Importance: Provide drinking water, irrigation, transport, fisheries, and hydropower.

  3. Lithospheric Resources (Land and Minerals) Examples: Soil, rocks, fossil fuels, metals (iron, copper, aluminum), non-metals (salt, limestone). Importance: Provide raw materials for industries, soil for agriculture, and fuels for energy.

  4. Climatic Resources Examples: Rainfall, temperature, humidity, sunlight, wind, dust.  Importance: Regulate agriculture, biodiversity and human settlements.

 Biotic resources are living (plants, animals, microbes). Abiotic resources are non-living (air, water, soil, minerals, sunlight). Both are interdependent and vital for the ecosystem and human.

Environmental Pollution

  Environmental Pollution Pollution Pollution is the introduction of harmful substances or pollutants or contaminants into the environment, causing damage to air, water, land or living organisms. It disturbs composition of natural resource. Pollution is occurred due to natural events or human activities and negatively impacts ecosystems and human health. It is classified into several types based on the medium (air, water and soil) it affects. There are main two types of pollution such as primary pollution and secondary pollution: Primary pollution include air pollution; water pollution and land pollution can be described as follows. Types of Pollution 1. Air Pollution Air pollution occurs when harmful substances, including gases, particulates (solid light particle for e.g. fly ash) and biological particles, are introduced into the Earth's atmosphere (air, space). This type of pollution can have severe consequences for both the environment and human health. These pollutan...

ENVIRONMENT: Nature, Scope, Type and Importance

ENVIRONMENT: NATURE, SCOPE, IMPORTANCE AND TYPES The word “ENVIRONMENT” originated from a French word “Environ”, which means “around” or to surround or to encompass or to encircle. This means that environment includes things or objects or events that surround us. It is believed that the subject has been introduced by the biologist Jacob Van Erkul in the early 1900s. Definition of Environment: “The environment is the sum total of all conditions, agencies and influences which affect the development, growth, life and death of an organism, species or race”. (The Universal Encyclopedia). Tansley (1935) a plant ecologist described the environment as the “sum total of those effective conditions in which organism live”. From the above definitions, environment refers to everything that surrounds us in which we live. Any external force which affects the life of an organism is a part of environment. Environment i...

Natural Resources, types, importance

                                  NATURAL RESOURCES A resource refers to anything that is available in nature or created by humans, which can be used to satisfy needs, wants and requirements. Resources are valuable for producing goods and services, improving quality of life and supporting economic, social or environmental goals. Natural Resources All resources which are available in the nature and useful for human welfare are known as natural resources or physical resources. Ex-air, water. Zimmerman defines resources ‘as means of attaining given ends. Resources satisfy human wants. The term resource means anything in the environment which has utility.   Definition   Erich W. Zimmerman defines a resource as not just a thing or substance but the function that the thing or substance performed in order to satisfy human needs and wants. It means a thing becomes resources b...
