A plant biologist studying the effects of CO₂ enrichment on plant growth observes that a certain plant species increases its biomass by 8% each week under elevated CO₂. If the initial biomass is 150 grams, what will the biomass be after 6 weeks? (Round to the nearest gram.)
["How Elevated CO₂ Boosts Plant Growth: A Study on Biomass Increase Over Time", "In the ongoing research on plant biology and climate change, scientists are closely studying how increased atmospheric CO₂ levels influence plant growth. Recently, a plant biologist observed remarkable results in a specific species that demonstrated consistent growth under elevated CO₂ conditions. The plant showed a remarkable 8% weekly biomass increase, a finding with significant implications for agriculture and carbon sequestration.", "Understanding how CO₂ enrichment affects plant development helps researchers predict crop yields and ecosystem responses to climate change. In controlled experiments, elevated carbon dioxide often accelerates photosynthesis and promotes faster growth, particularly in C3 plants like many common crops and wild species.", "One notable experiment involved a plant species that gained 8% in biomass each week under enriched CO₂. Starting with an initial biomass of 150 grams, this compound growth presents a compelling case study in plant physiology.", "To project the biomass after 6 weeks, we apply exponential growth formula:", "[\n\ ext{Final Biomass} = \ ext{Initial Biomass} \ imes (1 + \ ext{Growth Rate})^{\ ext{Number of Weeks}}\n]", "With a growth rate of 8% per week ((0.08)) and the initial biomass at 150 grams:", "[\n\ ext{Final Biomass} = 150 \ imes (1 + 0.08)^6 = 150 \ imes (1.08)^6\n]", "Calculating:", "[\n(1.08)^6 \approx 1.586874\n]", "[\n\ ext{Final Biomass} = 150 \ imes 1.586874 \approx 238.03 \ ext{ grams}\n]", "Rounding to the nearest gram, the plant’s biomass after 6 weeks reaches approximately 238 grams.", "This steady increase highlights the potential benefits of CO₂ enrichment—especially in greenhouse cultivation and future food production systems. However, extrapolating such growth in natural ecosystems requires careful consideration of water availability, nutrient supply, and species-specific responses.", "As environmental conditions continue to shift, plant biologists remain at the forefront, uncovering how life on Earth adapts to changing atmospheric chemistry—one leaf at a time.", "---", "Keywords: plant biologist CO₂ enrichment biomass growth 8% weekly increase, exponential plant growth, biomass calculation, climate change plant response, agricultural science, carbon dioxide photosynthesis effect"]
