Through research and development, a cable company has found a way to use its existing network lines to serve customers with a new product offering – home security systems. The company is offering the service for a lower monthly fee than most security companies. However, the sales force didn't see a lot of interest among its customers who had an existing security system from a competitor until they ran a promotion for reduced prices on equipment and free installation. Which of the competitive forces is at play?

ans.

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.'
