Final answer:
Biogeochemical cycles and recycling are examples of the law of conservation of matter as they involve the continuous movement and transformation of matter in ecosystems.
Step-by-step explanation:
The law of conservation of matter states that matter is neither created nor destroyed, but rather it is transformed from one form to another. Biogeochemical cycles and recycling are examples of this law as they involve the continual movement and transformation of matter in ecosystems.
In biogeochemical cycles, nutrients such as carbon and nitrogen are recycled and made available to organisms. For example, carbon is taken up by plants through photosynthesis and passed on to consumers through the food chain. When organisms die and decompose, the carbon is returned to the environment and can be taken up by other organisms, completing the cycle.
Similarly, recycling involves the collection and processing of waste materials to create new products. For instance, recycling paper allows the used paper to be transformed into new paper products rather than ending up in a landfill. This reduces the need for new raw materials and prevents the accumulation of waste.
