The use of the isotope 32P as a tracer element in the study of invasion and lysis of bacteria by viruses has shown that bacteriophage protein enters the bacteria.
Phosphorus-32 is a radioactive isotope of phosphorus, such that the nucleus of phosphorous-32 contains 15 protons and 17 neutrons, one more neutron than the most common isotope of phosphorous, phosphorous-31.

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
