1. Standing-Water Ecosystems Chapter 10 Section 2

2. Freshwater biomes can be divided into two main types – standing-water and flowing-water ecosystems. Lakes and ponds are the most common types of standing-water ecosystems. Can also include bogs, prairie potholes, swamps, and freshwater marshes. The top-level of a standing-water ecosystem supports the plankton community. Plankton is a general term for organisms that drift in the water.

3. Plankton that carry out photosynthesis are called phytoplankton and are the main producers in most aquatic biomes. Plankton that do not carry out photosynthesis are called zooplankton and include microscopic animals and protists. Wetlands are ecosystems in which the roots of plants are submerged under water at least part of the year. Marshes, swamps and bogs are a few examples.
