Plant Surface Area and Biomass: A 3/4 Power Relationship

Because B is predicted to scale proportionally to total M, theory predicts that the surface areas over which resources are exchanged with the environment are proportional to the ¾ power of the total plant biomass.

Sentence Breakdown:

• Subject: theory (理论)
• Verb: predicts (预测)
• Object: that the surface areas over which resources are exchanged with the environment are proportional to the ¾ power of the total plant biomass (环境中资源交换的表面积与植物总生物量成比例，且比例系数为3/4次方)
• Subordinate Clause Subject: the surface areas (表面积)
• Subordinate Clause Verb: are proportional to (成比例)
• Subordinate Clause Object: the ¾ power of the total plant biomass (植物总生物量的3/4次方)
