Answer: C. Both (a) & (b)
Continuous Forest Inventory offers superior accuracy under actual field growth conditions. The method avoids relying on static historical growth assumptions for future tree development. Both accurate measurement and free...
Answer: A. Primary consumers
In this food chain, water fleas feed directly on phytoplankton producers, classifying them as primary consumers. Primary consumers occupy the second trophic level by consuming autotrophic organisms that capture solar ene...
Answer: C. Field capacity
Field capacity represents the maximum amount of moisture a soil can retain after excess gravitational water has drained away. Once downward gravitational drainage ceases, the water remaining held by capillary forces defi...
Answer: E. All of the above
Watershed management aims to boost agricultural production and maintain affordable food supplies for populations. Increasing purchasing power and growing Gross National Product represent vital socio-economic objectives....
Answer: B. 40-60 dB
A standard face-to-face conversation produces acoustic energy measured comfortably in the moderate decibel range. Sound level meters record typical human speech hovering reliably between 40 and 60 decibels. This decibel...
Answer: B. Habitat destruction
Global wildlife populations are experiencing unprecedented declines driven primarily by human-induced pressures. The widespread destruction and fragmentation of natural habitats deprives animals of essential food and she...
Answer: D. All of the above
Watershed management strategies rely on integrating natural resources and sustaining proper land use. Producing quality water at the right time and place is vital for upland management. Public investment in major infrast...
Answer: E. All of the above
Direct sowing methods in forestry include broadcasting, dibbling seeds, strip or line sowing, and timing applications appropriately. Direct sowing bypasses nursery cultivation by placing seeds directly onto or into the p...
Answer: C. Energy only
Outer space primarily contributes radiant energy to Earth's ecosystems rather than physical matter or atmospheric gases. Solar radiation passing through space drives virtually all biological and thermodynamic processes w...
Answer: E. All of the above
Abnormal wood formation like reaction wood is influenced by mechanical forces including gravity and wind. Researchers like Metzger proved that tension and compression stresses trigger abnormal wood development. Changes i...
Answer: D. 5.5-6.5
A slightly acidic to neutral pH range maximizes nutrient availability for most cultivated crops. Soil acidity levels between 5.5 and 6.5 prevent essential minerals from becoming chemically locked. Maintaining this optima...
Answer: E. All of the above
Growing stock represents the entire population of living trees inhabiting a designated forest management area. Assessing growing stock requires analyzing diverse parameters including species composition and overall stock...
Answer: E. All of the above
Natural regeneration advantages include minimal soil disturbance and reduced manual labor requirements. Operational flexibility allows foresters to adapt management plans to prevailing local environmental conditions. Nat...
Answer: C. Both (a) & (b)
Drawbacks in certain management systems include restricting mature tree removal contrary to economics and yielding low returns from poor forests. Rigid sustained yield rules can force foresters to retain overmature timbe...
Answer: A. It is the process by which the crops constituting a forest are tended, removed and replaced by new crops, resulting in the production on woods of a distinctive form
A silvicultural system encompasses the practices used to tend, harvest, and replace forest crops to produce specific wood products. Silvicultural systems define the cyclical process of managing forest stands through thei...
