yes
They get food by the plants and animals living under the water and they get oxygen by the oxygen dissolved in the water
Lakes can vary in their oxygen content, but generally, well-mixed lakes tend to have higher oxygen levels throughout, while stagnant or polluted lakes may have lower oxygen levels. The oxygen content in a lake can also be influenced by factors such as temperature, depth, and the presence of plant and animal life.
After you Breathe in Oxygen and then exhale Carbon Dioxide back to the Atmosphere, plants will process the Carbon Dioxide BACK into Oxygen. They due this through the Photosynthesis Process. The Plants were the original source of the Oxygen. This includes Plants that are found in the Oceans, Seas, Lakes, etc.
The presence of cyanobacteria in high concentrations in lakes can indicate pollution due to excess nutrients, such as nitrogen and phosphorus, from sources like agricultural runoff or untreated sewage. Cyanobacteria thrive in nutrient-rich environments and can form harmful algal blooms, producing toxins that can be detrimental to aquatic ecosystems and human health. Absence of cyanobacteria in lakes may suggest a healthier, less polluted aquatic environment with balanced nutrient levels.
yes. lakes are a source for rivers because they help the water flow most of the time
Lakes

i think they used the water source by the lakes and rivers

ANSWER:Cyanobacteria. It is one of the earliest forms of life on Earth, and likely the FIRST form of life on Earth. EXPLANATION:Evidence (Fossilized Stromatolites) of the Cyanobacteria (the oxygen-producing bacteria) has been found as far back as 3.5 billion years ago. The Cyanobacteria is thought to have played a pivotal role in forming Earth's Atmosphere, because of its oxygenic photosynthesis (photosynthesis with a byproduct of Oxygen). Cyanobacteria is found in almost EVERY ENVIRONMENT: from Oceans (Salt Water), to Lakes and other fresh water, to bare rock and soil. This is further evidence that it has evolved longer than any other organisms, because of its (most-likely, evolved) survivability in such a variability of environments.
