Competition without division of resources may lead to

Answers

Answer:

Competition without division of resources may lead to extinction.

Explanation:

Some species are better adapted to live in an environment as compared to other species. If resources become scarce then the species with better traits might take up all the resources of a species which are not better adapted. This will cause the species with unfavourable traits to become extinct. To survive in an environment, an organism needs to change and adapt according to the conditions of the environment. Otherwise, the species will become extinct.

Or, some drugs can be inhaled as gases. Gases penetrate the lining of the esophagus and lungs very quickly, which allows the drug to enter the bloodstream. 
 Once a drug has entered the bloodstream,the blood throughout the body carries the substance with it. 
The digestive system is involved in the process of metabolism of the drugs. and transform drugs into substances that can be expelled by the body. Enzymes within the liver break down the drugs.
