2. false

True

Explanation:

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
