Ans.
Fats are complex biomolecules, made up of long hydrocarbon chains. For bears, meat and fishes are main source of fats. Fats provide essential fatty acids to the body that play various biological roles, such as in energy storage functioning of bones, and insulating vital organs.
When a bear cannot find meat, it will show a much lower intake of fats. Lower fat intake would lead to limit the supply of essential fatty acids as these molecules are produced by the digestion of fats.
Essential fatty acids molecules help in proper growth and functioning of bones, as they are necessary for proper calcium metabolism. So, limited supply of essential fatty acids will directly affect the bones and normal body functions.
Thus, the correct options are 1). essential fatty acids and 2). bones.
