What is the role of microscopic organisms in the pond ecosystem?

Answer 1

Microorganisms, by their omnipresence, impact the entire biosphere. Microbial life plays a primary role in regulating biogeochemical systems in virtually all of our planet's environments, including some of the most extreme, from frozen environments and acidic lakes, to hydrothermal vents at the bottom of deepest oceans, and some of the most familiar, such as the human small intestine. As a consequence of the quantitative magnitude of microbial life (Whitman and coworkers calculated 5 × 10 30 cells, eight orders of magnitude greater than the number of stars in the observable universe) microbes, by virtue of their biomass alone, constitute the single largest carbon sink. Aside from carbon fixation, microorganisms' key collective metabolic processes (including nitrogen fixation, methane metabolism, and sulfur metabolism) control global biogeochemical cycling. The immensity of microorganisms' production is such that, even in the total absence of eukaryotic life these processes would likely continue unchanged.

Answer 2

they eat, make more microorganisms, and die

Answer 3

Bacteria, protists (microbes not classified as bacteria) and algae are some of the many.

Answer 4

They slowly consume large amounts of water causing the body of water to slowly deminish.

Answer 5

Protozoa, Algae, Bacteria, Worms, etc.

Answer 6

Fish can eat them..
