Which term denotes the network of who eats whom within an ecosystem?

• A. Food web
• B. Trophic level
• C. Habitat
• D. Biomass

Answer: (A)

This question tests understanding of feeding relationships in an ecosystem and how energy moves between species. The network of who eats whom within an ecosystem is called a food web. It maps producers, various consumers, and decomposers, showing multiple, interconnected pathways for energy flow rather than a single straight line. This makes it a more accurate picture than a simple food chain, since many organisms have more than one prey or predator and energy can transfer through several routes. In contrast, a trophic level refers to a position on the energy ladder, a habitat is the place where an organism lives, and biomass is the total mass of living material in an area. So the network of who eats whom is the food web.
