Clay is rich in minerals but has poor aeration and sand has good aeration but lacks water holding capacity. The size of soil particles is largest in the case of sand and smallest in the case of clay. Loam is an ideal mix of clay and sand and it contains humus.

Niche refers to the totality of an organism’s adaptations, its mode of use of available resources, and the lifestyle in its community. It includes the mode of consumption of materials in its environment as well as its interactions with other organisms. Habitat portion of earthworm's fundamental niche refers to the soil while its role as decomposer is the realized niche. Thus, the correct answer is A.

Spiders and small insects are commonly found in various sheltered areas within human dwellings, including cupboards, drawers, and wall cracks.

Xeric environment means dry conditions or low atmospheric humidity and lack of precipitation. Also the temperature variations depend on several other variables like altitude, latitude and hemisphere. High rates of vapourisation is not a characteristic of environment but a consequence of low atmospheric humidity.

Yaks and mountain goats are well-adapted to the cold, high-altitude environments of mountain ranges.

Puri is a coastal city, making it the most likely location among the choices to find aquatic animals like crabs and fish.

Deserts are characterized by extreme aridity and very low precipitation, making them dry. Due to sparse vegetation and low humidity, temperatures fluctuate widely, but the defining climatic features are dryness and airy conditions.

Soil, water, and air are abiotic (non-living) components. A producer is a biotic (living) component.

Biotic potential is the maximum capacity of a population to reproduce under ideal conditions (environmental).

Biotic components are the living parts of an ecosystem. Producers, consumers, and decomposers are all living organisms that interact within the environment.
