Freshwater native mussels are a keytone species. They keep the harmful bacteria and algae population from exploding in addition to improving water quality through fliltering. A different species of mussels has invaded this river ecoystem. Reviewing the graph above, how has the presnce of the invasive mussels affected the population of native mussels?

Since there is no graph provided, I am unable to review it and provide an answer regarding the effect of invasive mussels on the population of native mussels. Please provide the graph or additional information for a more accurate response.

This is an example of competition in the natural world. Competition occurs when two or more individuals or species compete for a limited resource such as food, territory, or mates. In this particular scenario, the two laughing gulls are engaging in a competitive behavior as they fight over the sandwich left on the beach.

Laughing gulls are opportunistic scavengers, and they have developed a keen ability to identify and acquire food resources. When a sandwich is left unattended on the beach, it becomes a valuable food source for the gulls. Each gull wants to secure the sandwich for itself, which leads to a competitive situation between them.

To understand this concept further, you can observe and analyze similar behaviors in the natural world. You can study how different species compete for resources and how competition influences their behavior and evolutionary adaptations. Additionally, exploring the concept of competition in ecological studies will provide a broader understanding of how species interact and survive in various environments.
