Final answer:
An ecosystem consists of different organisms that interact with each other through what they eat and their relationships. These interactions can be represented by food chains or food webs.
Step-by-step explanation:
An ecosystem consists of different organisms that interact with each other through what they eat and their relationships. These interactions can be represented by food chains or food webs. In a food chain, energy flows from producers (plants) to primary consumers (herbivores) to secondary consumers (carnivores) and so on. However, food webs are a more accurate representation of ecosystems as they show the interconnected relationships between various species at different trophic levels.
