Organisms change and adapt to shifts in nutrient cycles in different ways:

1. Water Cycle:

   • Many plants grow deeper roots to find water. For example, desert plants can grow roots that reach as deep as 15 meters!
   • Animals often change where they live or how they behave, like migrating, to find water when it’s scarce.

2. Carbon Cycle:

   • When there’s more carbon dioxide (CO₂) in the air, plants can speed up a process called photosynthesis. Some plants can increase their photosynthesis by as much as 40%!
   • Certain bacteria can take in carbon even in tough environments, changing how they work to save energy.

3. Nitrogen Cycle:

   • Plants like peanuts team up with special bacteria that help them get nitrogen better. This helps them use nitrogen more efficiently.
   • Some organisms can switch the enzymes they produce to make use of different sources of nitrogen. This helps them absorb nutrients better when they are low in supply.

These adaptations help organisms survive and thrive, even when nutrients change in their environment.
