Web生态生产力（英語： ecological productivity ）是指生态系统中生物质的产生速率，通常以单位时间、单位体积（面积）的质量表示，例如克每平方米每天（gm-2 d-1 ）。质量单位可能与干物质或生成碳的质量有关。植物等自养生物的生产力称为初级生产力，而动物等異營生物的生产力称为次级生产力。 WebIn the case of optimal foraging, a type of optimality model known as a marginal value theorem is usually applied. As per this theorem, an organism should decide the economically favorable time to leave a patch while in search of food. The animal goes through the law of diminishing returns in a patch, as with time, it gets harder to find the prey.
