Crop monitoring makes use of space-based data to keep tabs on crop development and forecast crop yields for certain fields that have been planted.

<h3>What is monitoring systems?</h3>

A system for monitoring agriculture consists of a network with wireless sensors. These sensors gather information from several nodes positioned on the playing surface. Then, specialists or nearby farmers analyze this data. The data can be used to make a number of inferences about weather patterns, soil fertility, crop quality, etc. A system is developed for agricultural field monitoring in IoT-based modern agriculture with the aid of sensor like light, humid, temperatures, soil moisture, etc. Farmers may monitor the condition of thier fields from any location. IoT-based smart farming is considerably more efficient than conventional farming.

<h3>How do farmers monitor their crops?</h3>

Nowadays, satellite techniques are widely employed in agriculture, and many farmers use them frequently to observe their fields and assess the condition of their crops. Crop monitoring is crucial for managing various pests, weeds, and diseases that affect crops. This gives information about the crop's current situation, and you can then look ahead in time to forecast what will probably be the crop's next problem.

Sara is studying the human skeletal system. Her classroom has a model skeleton. What main advantage does a model skeleton have o
frosja888 [35]

Answer:

A scientific model is a representation model for a certain scientific concept. Scientific models make it easier to study a phenomenon as they tend to model out the exact phenomenons.

A drawing of an skeleton would be unclear as the children might not be able to locate certain features in the drawing. For example, a certain joint could be missed by the teacher in the drawing or the child might not exactly be able to locate where the joint or bone is present.

But as the model will be more real to the actual skeleton system hence, studying through a skeleton will make it a lot easier to study the human skeletal system.
