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
The first reason is that Thats because the seeds will remain dormant until they have the resources they need for eg: some seeds are frozen in winter so that they wont germinate until they have enough resources in spring .
