Q. Consider the following as examples of the grazing food chain:

1. Grassland
2. Pond
3. Forest

Which of the above are correct examples of a grazing food chain?
Answer: Only 1 and 2
Notes: Grazing food chains are typical of grassland and pond ecosystems, where herbivores or primary consumers such as cattle or zooplankton feed directly on producers. In forests, however, the primary consumers—mostly insects—consume a small fraction of primary production, making the predominant food chain a detritus (decomposer) chain rather than a grazing one.
