At its present rate of output, Barrel O' Biscuits, a perfectly competitive firm, finds that its marginal cost exceeds its marginal revenue and its price exceeds its average variable cost. To maximize profit, the firm should

Reduce output

Explanation:

 According to the given question, the barrel O' Biscuits is one of the type of perfectly competitive organization in which its overall marginal cost increasing the company's marginal revenue.

 For maximizing the profit of an organization then we should reduce the output as in the perfect competition the company majorly affected the output only and for shift the overall marginal cost of the company we reducing the output.

 Therefore, Reduce output is the correct answer.      

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.'
