Define ‘nagarams’.


Crops are impacted by both biotic and abiotic factors.

Biotic factors:
The texture of the soil is improved by earthworms.
Soil fertility is increased by microbes such as nitrogen-fixing bacteria.
Insects act as predators, keeping the number of crops in check.

Abiotic factors:
Photosynthesis is aided by sunlight.
The raw resources for the synthesis of food and energy are water and minerals from the earth, as well as gases.
For proper plant growth and numerous activities such as transpiration, a suitable temperature is essential.
Plants require rainfall for natural irrigation.

Final answer:
Hence, biotic factors like soil texture, fertility, insects etc., and abiotic factors like sunlight, water and minerals, temperature, rainfall etc. affect crop production.
