Feed cost is one of the important variable costs that plays a big role in determining the poultry cost. Variable costs rise and fall with the size of the output and the level of the operation. Fixed costs (for items such as taxes, insurance, interest, and depreciation on buildings and equipment), are incurred whether or not there is any output.

Correct Option: A

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. The nature of the organisms—the species, functional groups and trophic levels to which they belong—dictates the sorts of actions these individuals are capable of carrying out, and the relative efficiency with which they do so.

Myopia, commonly known as nearsightedness, is a vision condition in which close objects are seen clearly, but objects farther away appear blurred. It occurs if the eyeball is too long or the cornea, the clear front cover of the eye, has too much curvature. Concave lenses or corrective surgery is used to correct this defect.

Living beings are systems or organisms that tend to respond to changes in their environment and inside themselves, in such a way as to promote their own continuation and longevity. They have the ability to breathe or respire, move or navigate and the ability to multiply. Living organisms include human beings, plants, insects, animals among others.

Ossification is the process of laying down new bone material by cells called osteoblasts. It is synonymous with bone tissue formation. As per scientific evidence, by the age of 25 years nearly all bones are completely ossified in humans. Ossification test is a guess work based on the fusion of joints in the human body b/w birth and age 25. If all joints are fused the person must be of 25yrs of age or older.
