All habitat needs food,water and shelter to survive. For example, a change in the community could be that the seals population decrease causing a lot of sharks to die off, but once the sharks die more seals would live and the population will go back up.  

LIMITING FACTORS

an environmental factor that tends to limit population size.

temperature, sunlight, pressure, oxygen concentration and nutrient availability

(predator/prey/relationship)

sharks eat seals, but if seals don't get enough food and water they will die and the sharks population would decrease because they wont have any food to eat. Or if the shark does not get the food they would die and the seals population will increase
