Which row identifies three secondary consumers as identified in the food web?

In a food web, the secondary consumers occupy the second row.  

Explanation:

The bottommost row is occupied by the producers which produces their own food like the plants

Primary consumers in the first and secondary in the second row from the bottom row

The consumers consume the primary producers for energy production. Consumers are further classified as primary, secondary and tertiary consumers.

While the primary consumers are herbivores eating only plants, the secondary consumers are omnivores and consist of both ominivores (bears) and carnivores (snakes). The nutrition of secondary consumers is heterotropic nutrition. They are found in all type of ecosystems including terrain and aquatic systems.  

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
