1. Factors Influencing Species Survival

2. Carrying Capacity
The carrying capacity is the size of a population that can live indefinitely using the resources available where that population lives

3. For example, consider an island onto which is dropped a colony of rabbits. As long as there is an adequate supply of food and water, the rabbits will not only survive but they will reproduce and the colony will get larger.
The rabbit population can continue to grow as long as food and water are adequate. However, if at some point, there are more rabbits that there is food to feed them, then the rabbit population will start to decline

6. Biotic Potential
Biotic potential is the maximum reproductive capacity of a population  if resources are unlimited. Full expression of the biotic potential of an organism is restricted by environmental resistance , any condition that inhibits the increase in number of the population.

7. It is generally only reached when environmental conditions are very favorable. A species reaching its biotic potential would exhibit exponential population growth and be said to have a high fertility, that is, how many offspring are produced per mother

9. Environmental Resistance
he effect of physical and biological factors in preventing a species from reproducing at its maximum rate.  factors in an environment such as predators,  competition, climate, and food availability, that keep its various populations from reaching their maximum growth potential

11. Exponential Growth
Rapid Growth of organisms multiplying in each generation
If a population has a constant birth rate through time and is never limited by food or disease, it has what is known as exponential growth. With exponential growth the birth rate alone controls how fast (or slow) the population grows.
