Question

1. nutrients move through an ecosystem in ________. * pyramids of energy ecological pyramids water cycles biogeochemical cycles

Explanation:

• Pyramids of energy show energy transfer in an ecosystem, not nutrient movement.
• Ecological pyramids represent trophic level relationships (like biomass, number of organisms), not nutrient cycling.
• Water cycles focus on water movement, not general nutrient movement.
• Biogeochemical cycles (e.g., carbon cycle, nitrogen cycle) describe how nutrients (chemical elements) move through the biotic (living) and abiotic (non - living) components of an ecosystem.

Answer:

D. biogeochemical cycles
