What best describes the movement of energy?
Answer: Energy flows from high to low is the correct answer. Explanation: (Energy flows from high to low) best describes the movement of energy.
Which of the following would be expected to have the greatest impact on primary productivity?
Solar energy would have the greatest impact on the primary productivity.
Which data is most useful to measure primary productivity in terrestrial ecosystems?
As such it is available for consumption by herbivores. Both gross and net primary production are typically expressed in units of mass per unit area per unit time interval. In terrestrial ecosystems, mass of carbon per unit area per year (g C m−2 yr−1) is most often used as the unit of measurement.
How is Hanpp calculated?
NPPh includes primary crop harvest but also harvest losses, i.e. residues or biomass destroyed during harvest, grazing and humaninduced fires. Based on the above HANPP is therefore defined according to the formula: HANPP = NPP0 – NPPt with NPPt = NPPact – NPPh.
What would cause changes in Hanpp over time?
Unlike rising crop yields, increasing harvest from forest land and the expansion of land occupied by infrastructure, buildings, and associated land have contributed to increasing HANPP (Fig. 1A).
What is the process of primary productivity?
Primary productivity is the process by which organisms make their own food from inorganic sources. The majority of primary producers are terrestrial plants and microbial life, such as algae. Primary productivity due to photosynthesis is commonly measured by quantifying oxygen production or CO2 assimilation.
What are the examples of primary production?
Primary production: this involves acquiring raw materials. For example, metals and coal have to be mined, oil drilled from the ground, rubber tapped from trees, foodstuffs farmed and fish trawled. This is sometimes known as extractive production.
What are the three types of industries?
What are Three Different Types of Industries – Primary, Secondary & Tertiary?
- Primary industry. The primary industry includes the economy that utilises the natural resources of the environment like forestry, agriculture, fishing, and mining.
- Secondary industry.
- Tertiary industry.
What are the 5 types of industries?
Industry sectors
- Primary sector of the economy (the raw materials industry)
- Secondary sector of the economy (manufacturing and construction)
- Tertiary sector of the economy (the “service industry”)
- Quaternary sector of the economy (information services)
- Quinary sector of the economy (human services)
