Nitrogenous waste of the body are excreted by organisms of different species differently. Others, such as the mammals excrete it in a form of urea while other in a form of ammonia. Still others, excretes it in a form of uric acid. The latter group of organisms being referred to are the BIRDS and REPTILES.
This organisms found to excrete the nitrogen as urea are called as uricothelic organisms and excrete white powder or paste. The process of conversion of ammonia to uric acid needs a lot of energy or energy intensive, however; it is less toxic and reduces need for water.
Characteristics that are always present in living organisms are Metabolism, Cells and Reproduction.
The answer is true

Answer:
True
Explanation:
Reproduction is one of the essential characteristics of all living beings. However, if they reproduce to their full capability, the number of offspring would be higher than the available resource. Due to this reason there is always shortage of resources and hence competition arises among the species.
The fit species survive among all the competing species while the remaining weak species die. As Darwin also said that species have the ability to reproduce uncontrollably therefore, competition among the species for survival is a mode of population regulation
Hence, the given statement is true
