Question

Freshwater ecosystems are categorized according to the speed of water flow. There are ……………. ecosystems of non-flowing water and ………… ecosystems of flowing water.

Answer 1

Hint: Freshwater ecosystems are a subset of Earth’s aquatic ecosystems.
There are many types of freshwater ecosystems. Rivers, lakes, ponds, and streams are the most
common freshwater sources. Reservoirs, wetlands, and groundwater sources are also considered freshwater ecosystems.

Complete step by step answer: A lentic ecosystem entails a body of standing water, ranging from ditches, seeps, ponds, seasonal pools, basin marshes, and lakes. Deeper waters, such as lakes, may have layers of ecosystems, influenced by light. Ponds, due to their more sunlight penetration, are able to support a diverse range of water plants.
-A lotic ecosystem can be any kind of moving water, such as a run, creek, brook, river, spring,
channel, or stream. The water in a lotic ecosystem, from source to mouth, must have atmospheric gases, turbidity, longitudinal temperature gradation, and material dissolved in it.
So, the answer is - Freshwater ecosystems are categorized according to the speed of water flow. There are ……lentic……… ecosystems of non-flowing water and ……lotic…… ecosystems of flowing water.

Note: Lotic ecosystems have two main zones, rapids and pools. Rapids are the areas where the water is fast enough to keep the bottom clear of materials, while pools are deeper areas of water where the currents are slower and silt builds up. Lentic and lotic ecosystems can be destroyed through natural or human interaction. Lentic and lotic systems may succumb to such things as climate change, being dammed, drained, filled, or undergo an invasive species invasion. A freshwater ecosystem can be contrasted with marine ecosystems, which have a larger salt content.
