Which of the following is an example of a system? select one: a. a leafb. a river drainage basinc. a mid latitude cyclonic stormd. all of these are examples of systems. e. none of these are examples of systems.

Option (D)

Explanation:

A system is defined s the group of elements that interacts with one another, exchanging both matter and energy. For example, human beings are an excellent example of an open system.

A system is divided into 2 types-

1) Closed system

2) Open system

The given options are an example of an open system.

Leaf is an example of an open system as it directly interacts with the atmosphere. The leaves play an important role in releasing the excess amount of water back into the atmosphere by the means of the evapotranspiration process.

Drainage basin is the area over which the water flows after precipitation, and mixes up the rivers, seas, and oceans. It interacts directly with the atmosphere. It is also known as the watershed area.

Mid-latitude cyclones are the cyclones that usually occur in the latitude of about 40-50 degrees. Due to the various atmospheric condition, these cycles are generated and are an example of an open system.

Thus, the correct answer is option (D).
