A) Biotic and abiotic

Biotic resources refer to resources that are derived from living organisms or are produced by living organisms. These include plants, animals, and microorganisms. Examples of biotic resources include forests, fish, livestock, and crops.

Abiotic resources, on the other hand, are derived from non-living things or are not produced by living organisms. These include minerals, rocks, air, water, and sunlight. Examples of abiotic resources include coal, oil, natural gas, metals, and water bodies.

Explanation:
Resources can be classified into different types based on various criteria. One way to classify resources is based on their origin. The origin of resources refers to whether they are derived from living organisms or non-living things.

Biotic resources are derived from living organisms or are produced by them. These resources are typically renewable in nature as they can be replaced or replenished through natural processes. For example, forests can be replanted, fish populations can be replenished through breeding, and crops can be grown again in the next growing season. Biotic resources are essential for the survival and well-being of living organisms, including humans.

Abiotic resources, on the other hand, are derived from non-living things or are not produced by living organisms. These resources are generally non-renewable or have a very slow rate of replenishment. Once these resources are depleted, they cannot be easily replaced within a human lifespan. Examples of abiotic resources include fossil fuels like coal, oil, and natural gas, which take millions of years to form. Other abiotic resources include minerals like iron, copper, and gold, which are extracted from the earth's crust.

In conclusion, the classification of resources based on their origin helps us understand their source and characteristics. Biotic resources are derived from living organisms and have the potential for renewal, while abiotic resources are derived from non-living things and are often non-renewable or have a slow rate of replenishment. Both types of resources are important for human survival and development, and their sustainable management is crucial for the long-term well-being of our planet.
