Pssst… Imagine if we humans had a limit to how many slices of pizza we could devour? Well, similar rules apply to nature – and they're called the "carrying capacity". ๐Ÿ•๐ŸŒ

Carrying capacity - the elastic band effect

  • Every species has a certain "carrying capacity" - the maximum population that an environment can support.
  • This is like a bungee cord – the population size can stretch up and down but it generally hovers around the carrying capacity.
  • So why does it bounce? Factors like changes in resources (think food shortage) or the abiotic environment (like an extreme weather event) can affect it.
    Real World Example: Remember the fish in your aquarium? If you feed them too much or change the water temperature, the fish population might change, showing a similar fluctuation. ๐Ÿ 

Role of competition & biotic interactions

  • Not only the non-living factors, even the living guys play a part. The competition for resources and other biotic interactions can lead to changes in the carrying capacity.
  • Real World Example: Just like when you and your sibling fight for the last piece of pizza, animals and plants also fight for resources like food and space, impacting their numbers. ๐Ÿ•
