Producers and consumers

Explanation:

Interactions between suppliers and consumers regulate economic activities in a free market economy. Demand and supply determine the goods and services to be produced and availed in the market. Suppliers represent the supply side, while consumers represent the demand.

Suppliers are profits motivated. They will supply goods and services that will generate high profits. These are the goods that consumers demand more.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
