- A conceptual model representing the role, interaction, reaction, and density of essential ecosystem components is shown below. Examine the model and the relationships between the major players (i.e., predator, prey, producer). The structure's most important role is played by these major players. It's also worth noting that nutrition has been included in the model. This is the abiotic component that has a direct or indirect impact on the interaction.
