THE SENSE ORGANS, The sense organs are the organs which receive stimuli and with the help of the brain (voluntary action), the message is received and interpreted. Hence, such organs enable animals to respond to stimuli within the environment.
SENSE ORGANS OF FARM ANIMALS
sense Organs of farm animals include the eyes, ears, kidney, liver, skin, nose, tongue, lungs and heart. although there are 5 major sense organs of animals but here i am treating farm animals. Most of these organs have already been discussed in this posts here. However, the structure and functions of the skin, kidney and liver are discussed here in detail. The five senses of the body are sight, sound, smell, taste, and touch. The five senses of humans are perceived through the use of sense organs. These sensory organs include eyes for sight, ears for sound, nose for smell, tongue and nose for taste, and skin for touch. The function of each sense is to help humans perceive the world so that we may make decisions about what is happening and what is needed in a situation.
The sense organs include: (i)nose – sense of smell (ii)Eyes – sense of vision(sight) (iii)Ears – sense of sound (hearing) (iv)Tongue – sense of taste (v)Skin – sense of touch and heat. Specialized organs consisting of sensory cells that respond to the external stimuli to convey impulses to the sensory system of the body are known to be sense organs.
Sensory organs play an important role in a variety of functions and help in perceiving our surroundings. These are an integral part of our bodies that enable us to sense the environment around us. Sensory organs and their receptors trigger numerous stimuli that are then transmitted to the brain. A network of nerves and sense organs is associated with interpreting data in response to a special physical phenomenon. This is the way that decides our interaction and response to the environment.
the Ear
The organ for the sense of hearing is ears. Hearing or auditory perception is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear.

What is land in economics?
Land in economics does not only include land surface of the earth but all other free gifts of nature or natural resources like forest, mineral resources, rivers, oceans and atmosphere. Unlike other factors of production, the supply of land is limited. The reward for land is rent
Characteristics or features of land
- Land is immobile: Land cannot be moved from one geographical location to another
- The supply of land is fixed: It is practically impossible for man to increase the quantity of land.
- Land is a free gift: Land is given freely by nature.
- Land is subject to diminishing returns: When a piece of land is frequently bought under cultivation, it becomes less productive
- Variability: The quality and value of land varies from one place to another as some areas of land are more fertile than others
- Rent: The reward for land is classified as rent
- Land has no cost of production: No cost was involved in bringing land into existence
- Land is heterogeneous: No two parcels of land are the same in value or in other characteristics
