Mainly size, rate of Metabolism (Faster equals quicker ageing) and the speed they move also seems to have some relation in some cases.
Size
Heart rate
predation
available food sources
environment
One species is stronger then the other because of certain characteristics like more legs.
the main thing is the rate of cell division the same mechanism in machines u use them continuously for a longer time it gets worn out thats as simple as it is
compare and study tings u can understand a lot
Generally speaking, there are two main factors: Survival and reproductive ability. A species which lives longer and has a high rate of reproduction generally has a higher chance of producing more individuals, ensuring survival of that species.
However, in reality there are other factors to consider. The number of offspring which survives and reproduces in the next generation has to be taken into account. For example, if an individual produces a high number of offspring many of the offspring may die due to predation and lack of parental care. Another strategy is to produce fewer offspring, allowing greater parental care and ensuring a high proportion survive and reproduce.
Another approach to the question might consider the biotic and abiotic factors which lead to differential evolutionary success of a species. For example, ability to escape from predators, to avoid detection from predators, ability to catch prey, ability to capture sunlight for photosynthesis, ability to metabolise different nutrients etc.
