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.
Question: Why does the organism’s interaction appear in an oscillating pattern? What does it suggest?
Also from the biological standpoint, several types of ECOSYSTEM and their corresponding components are distinguished.
Select one type of these ecosystems that you can find near your place of residence. Identify that specific type of ecosystem.
Categorize the component organisms present ONLY in that particular ecosystem.
Using these representative organisms (those given in 2b above), make a diagram to clearly illustrate a food web to show the flow of energy in that ecosystem.
