Answer 1

Answer:

B. i, ii

• The types of primary producers vary significantly between different ecosystem types.

• In terrestrial environments, the vast majority of biomass and energy production comes from land plants.

• In aquatic systems, especially open oceans, microscopic phytoplankton are the primary producers, forming the base of the marine food web.

• Macrophytes, while also producers, are rooted plants found in shallow aquatic environments like lakes and coastal areas, rather than terrestrial ones.
