compare the productivity of terrestrial and aquatic ecosystems against the percent of earths surface area…

Answer:

Terrestrial ecosystems cover about 29% of Earth's surface area. They have a wide - range of productivities depending on the biome (e.g., tropical rainforests are highly productive while deserts are low - productive). Aquatic ecosystems cover about 71% of Earth's surface area. The open ocean, which is a large part of aquatic ecosystems, has relatively low productivity per unit area but high total productivity due to its vast area. Coastal and estuarine aquatic ecosystems can be highly productive. Overall, while aquatic ecosystems cover a larger percentage of Earth's surface, the total productivity between terrestrial and aquatic ecosystems is relatively balanced when considering the different productivities within their sub - ecosystems.

Brief Explanations:

Based on knowledge of ecosystem distribution and productivity. Terrestrial ecosystems vary by biome, and aquatic ecosystems have different productivities in open ocean and coastal areas. Total productivity is a balance of area and per - unit - area productivity.
