Answer:
True
Step-by-step explanation:
The statement, "Aquatic ecosystems support more primary producers proportional to their area than terrestrial ecosystems" is true . This is because aquatic ecosystems, such as oceans, lakes, and rivers, contain more available nutrients for plant growth in the form of dissolved minerals and organic matter, allowing for a greater density of primary producers (plants and algae) per unit area. Additionally, the buoyancy provided by water allows aquatic plants to grow more upright, exposing a greater surface area to sunlight. However, it is important to note that terrestrial ecosystems can have greater overall primary productivity, as well as greater diversity and complexity of plant life.
