Answer 2

Net primary production and peat soil

Explanation:

• During breathing, around 40 to 85 percent of gross primary productivity is lost and becomes net primary productivity.
• In terrestrial ecosystems, swamps and marshes, as well as tropical rainforests, have the highest net primary productivity, whereas deserts have the lowest.
• Deserts and arctic tundra ecosystems are the least productive because they are limited by heat energy and water.
• Ecosystems with high temperatures, plenty of water, and plenty of accessible soil nitrogen are the most productive.
• The rate at which plants and other photosynthetic creatures generate organic substances in an ecosystem is referred to as primary productivity.
• Deserts, tundra, the open ocean, and the lakes and streams biome all have the lowest amounts of primary productivity.
• As a result, the right answer is 'Open Ocean.' Peat is known for its high natural moisture content, compressibility, and water-holding capacity, as well as its low specific gravity, low bearing capacity, and medium-to-low permeability.
• As a result, classification and upgrading of peat are required before any form of infrastructure can be built on it. Peatlands are where they can be found (also called bogs or mires).
• Peatlands are found in temperate (Northern Europe and America) and tropical regions and cover around 3% of the earth's geographical mass (South East Asia, South America, South Africa and the Caribbean) 1. Histosols are a type of peat soil.
