Which sequence shows the correct order of living things in a food chain?
kkurt [141]

The correct answer is option (A) leaves > deer > wolf.

A food chain is a linear sequence of organisms through which the nutrients and energy flow as one organisms feeds on the other. They show organisms starting from the producers and end with consumers or sometimes with detrivores or decomposers. Each level of the food chain is called the trophic level. The producers which use solar energy and prepare their food occupy the first trophic level, followed by the primary, secondary, tertiary, quaternary consumers occupying the next trophic level.

In the food chain given above, leaves > deer > wolf, deers feed on the leaves which are maximum in number comparitively, wolf feeds on the deer which are comparitively more in number than the wolves. This is the correct sequence of food chain showing the tranfer of energy and decreasing number of organisms with subsequent increase in the trophic levels.
