BOTANY

Which of the following is an example of a grazing food chain?

A grazing food chain starts with living producers like grass or algae and is consumed by herbivores and carnivores. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

SPECIES INTERACTION

A grazing deer is an example of:

A deer consuming grasses, herbs, leaves, or shoots is functioning as a herbivore because its food comes from living plant tissue. Herbivory is a consumer-resource interaction that usually removes only part of a plant, allowing the individual plant to survive, unlike a predator that commonly kills one prey animal per feeding event. Deer may occasionally ingest nonplant material, but their morphology, rumen microbiota, and typical diet are adapted for processing cellulose-rich vegetation. A parasite maintains a prolonged intimate association with a host, whereas an omnivore routinely obtains substantial nutrition from both plants and animals. Grazing therefore demonstrates the ecological feeding role of herbivory. From an evolutionary perspective, traits persist when their net effects improve inclusive or direct fitness under prevailing conditions. The ecological terminology therefore summarizes both an immediate mechanism and its likely consequences across generations. A careful interpretation retains the assumptions of the underlying model and avoids extending it beyond available evidence. Within those assumptions, the keyed concept gives the most consistent account of the biological pattern and its expected outcome.
