Therefore, if the population of top level consumers is decreasing, this indicated that the secondary consumers population is reducing, due to reduction in energy obtained from primary producers which has dropped due to the decline in productivity.Hence nothing fort the top consumers to feed on.

The right option is; Thermoreceptors
Thermoreceptors helps her adjust to the change in the temperature of her surroundings.
Thermoreceptors are specialized nerve cells that are sensitive to detect changes in heat energy (temperature). Thermoreceptors are found in every part of the skin. They detect heat and cold, therefore, they allow sensory reception within the body. The sensitivity of the skin to temperature changes is based on the number of thermoreceptors and where they are located.
