Mutualism can change into parasitism over time. This change depends on the environment and how species adapt to it.

Key Points:

1. Mutual Relationships:

   • In mutualism, both species get something good out of the relationship.
   • A great example is bees and flowering plants.
   • About 80% of flowering plants need animals like bees to help them reproduce.

2. Changing Conditions:

   • When resources (like food) become less available, it can change how species interact.
   • If one species starts taking more than it gives (like eating more food than it shares), the relationship can change.

3. Research Findings:

   • Studies show that 10-50% of mutual relationships might change into parasitism over time.
   • For example, some parasites used to be helpful partners but have changed over the years.

In summary, while mutualism is good for both sides, changes in the environment can turn these relationships into parasitic ones.
