Final answer:
The incorrect statement about matter in the biosphere is that the total amount of matter decreases over time, which contradicts the conservation of mass principle represented in biogeochemical cycles.
Step-by-step explanation:
The question pertains to matter in the biosphere and its relation to biogeochemical cycles. The statement that is NOT true about matter in the biosphere is: c. The total amount of matter decreases over time. In contrast, the total amount of matter actually remains consistent over time due to the recycling of nutrients and elements through biogeochemical cycles. These cycles ensure that elements like carbon, nitrogen, and water are reused continuously, involving both biotic (living organisms) and abiotic (nonliving factors) components of ecosystems. Thus, option a, b, and d are true because matter is indeed recycled, biogeochemical cycles transform and reuse molecules, and the total amount of matter does not change over time according to the principle of conservation of mass.
