freshwater marshes Biology Diagrams Freshwater ecosystems include rivers, lakes, ponds, and streams, where life prospers in the flowing and still waters. These ecosystems begin with microorganisms and aquatic insects, providing sustenance for fish, amphibians, and birds.. These food chains are susceptible to changes in water quality, temperature, and flow and used as indicators of environmental health.
This food web shows the role played by invertebrates (animals without backbones), such as mayflies and stoneflies, in freshwater ecosystems. The arrows indicate what eats what. Invertebrates feed on living and dead plant matter, and on each other. Invertebrates are an important link in the food

The freshwater pond ecosystem is finely balanced because of the food chain close food chain A sequence (usually shown as a diagram) of feeding relationships between organisms, showing which The Cyclical Nature of the Food Chain A cyclical food chain means that even the most fearsome creatures can become a source of nutrients to lower-order consumers and decomposers. Rawpixel Ltd / CC BY 2.0. In any type of ecosystem, a "food chain" can be defined as a series of organisms depicting the transfer of energy (in the form of The freshwater food web shows us all the connections between food chains in an ecosystem. The web gets even more complex with omnivores , which eat both plants and other animals!
The freshwater pond ecosystem close ecosystem The living organisms in a particular area, together with the non-living components of the environment. is finely balanced because of the food chain A food chain refers to a linear sequence of organisms showing how energy or nutrient flows through an ecosystem when one organism consumes another for its survival.It provides information about which species eats which other species in nature. Typically, a food chain is represented by a diagram where arrows show the direction of energy and nutrients flow. A food chain in a grassland ecosystem may consist of grasses and other plants, grasshoppers, frogs, snakes and hawks (Figure 8.3). In a freshwater aquatic ecosystem like a pond, the organisms in the food chain include algae, small animals, insects and their larvae, small fish, big fish and a fish-eating bird or animal (Figure 8.4). A food chain
