b)grassland
c) wet tropical forest
D)agroecosyatem​

Answer 1

Answer:

a) open ocean. I think it must be the answer

Answer 2

Gross primary productivity is the highest in wet tropical forest. (option C)

• In lowland moist tropical forests, GPP is between 30 and 40 Mg C ha-1 year-1 and decreases with altitude.
• Because of their high temperatures, high levels of humidity, and high levels of rainfall, which encourage the growth of more trees, moist tropical rainforests are the most productive.
• Due to the appropriate yearly temperatures and precipitation levels for plant growth, tropical wet forests have high net primary production.
• Consequently, the large amount of biomass found in tropical wet forests creates plant communities with a relatively high species diversity.
• Because there is a plenty of water and sunlight, tropical rainforests have high primary productivity.
• Because it is shallow (gets lots of sunlight) and contains turbulent water, a typical estuary has a high primary productivity. (which brings nutrient rich material from sea bed).

Hence, Gross primary productivity is the highest in wet tropical forest.
