Biotic factors are important for keeping ecosystems steady. Here are some ways they help with this balance:

1. Species Interactions:

   • Predation: This is when one animal eats another. It keeps animal populations in check, making sure no single animal takes over the ecosystem.
   • Competition: Different species compete for resources. This drives them to adapt and find their own roles, which makes the ecosystem more diverse.

2. Nutrient Cycling:

   • Decomposers, like fungi and bacteria, break down dead plants and animals. This process returns nutrients to the soil, which helps new plants grow.

3. Mutualism:

   • Some species help each other. For example, bees pollinate flowers. This relationship helps both plants and bees survive, making the ecosystem stronger.

4. Disease Dynamics:

   • While diseases can control populations, too much illness can harm ecosystems, especially if it affects important species.

In summary, the way biotic factors interact creates a balance that helps ecosystems adjust and thrive over time!
