It is complex because of the many organisms in the ecosystem.
In the agricultural practices cover plants are grown for the enrichment and the protection of the soil. They are not harvested to be sold as cash crops.
<h3>What are the cover crops used for?</h3>
Cover crops are grown in the agricultural land parts to maintain the soil fertility and quality so that the land will be safe from the invasion and attacks of pests and weeds.
They are generally grown after the reaping of cash crops and help in soil binding by preventing erosion from the water runoffs.
These plants help in fixing the nitrogen content of the soil and help the soil to remain fertile and nutrient-rich. They increase the organic and the mineral compounds to the soil profile and enriches the soil quality.
Therefore, option c. they are sold as cash crops is incorrect.

ANSWER:
Electromagnetic energy is monitored by scientists forecasting future space weather
EXPLANATION:
Electromagnetic energy has such type of waves which propagate or radiate through space, carrying photons. Electromagnetic energy has radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays.Space weather includes any activity happening in space that might affect Eath's environment.Space weather can interrupt mobile signals,air communications and can damage our satellites.So Electromagnetic waves are monitored to control all the above situations.
Answer:
The correct answer will be option-D
Explanation:
Pulmonary Surfactant is a complex substance produced by the pneumocytes epithelial II cells in the alveolar sac.
The surfactant is composed of the proteins and lipids which plays a role in keeping alveoli open by reducing the surface tension formed between the air and liquid.
The surfactant act by forming a monolayer surface film which helps reduce the surface tension.
Thus, option-D is the correct answer.
