1. Interrelation of the species in the Ecosystem- Assignment

Ecosystems are communities of organisms that interact with one another and with their physical environment, including sunlight, rainfall, and soil nutrients. Organisms within an ecosystem tend to interact with one another to a greater extent than do the organisms between ecosystems (Masten and Davis 2020). The interrelationship of species in an ecosystem is a complex web of interactions that occur between different organisms within a particular environment. These relationships are crucial for maintaining the balance and stability of the ecosystem.
