B. Greenhouse effect
C. Photorespiration
D. None of the above

Answer 1

Hint: It is a type of cultivation where sand is not used to cultivate plants. Plants are cultivated in nutrient solution to grow. It is a type of hydroponic cultivation.

Complete answer:
Cultivation is the feeding or rearing of plants. The main aim of cultivation is to transform the soil into a fine tilth in order that seeds germinate in the optimum environment. The conventional method of weed control was cultivation as well. Most European countries have a cold and wet atmosphere, which allows organic matter to build up on soils when grown.
Sand cultivation is a form of hydroponic cultivation without soil. It is a difference in gravel cultivation in which sand, used mostly to anchor plants in the bed or tray is much finer than the gravel medium choice. All nutrients are provided to the plants with nutrient solutions that fulfil the requirements of the plants in a soilless cultivation. Solution composition refers to the concentration in the solution of each nutrient ion. Various types of composition have been drawn up and the composition should be selected according to plant form, growth level, product goal consistency, etc.

Hence, the correct answer is option (A)

Note: The stresses on land and soil erosion and the depletion of land or soil are an important challenge in farming in modern times. Any of these problems can be addressed by sand plant cultivation. Plants are planted in nutrient solution in sand cultivation.
