The Earliest Microscopes and Pond Ecology

The rotating nosepiece holds two or more objective lenses with different target magnifications. Many microscopes have an aperture or aperture to control the intensity and magnitude of the light. All of these components under the microscope help to observe the sample. The ecology of the pond is the interaction between the pond's life and the environment. This pond has a low oxygen content, the animal's life is short, and the supply of food is insufficient. Water mainly contained in the pond, there are few nutrients, aquatic life is few. Creatures live, grow and die in ponds.

The ecology of the pond is best explained as the interaction between the life of the pond and the environment there. It is a shallow, nutritious pond, almost no water flows, it is exposed to the sun, filled with algae and aquatic plants. Due to its low oxygen content, it may be that few animals exist. In contrast, the new deep-sea hot spring pool may have little life expectancy due to low temperature and lack of food supply. Every pond is obsolete. At the beginning the pond is primarily water, with less nutrients and fewer aquatic life. Over time, the pond has accumulated nutrients. This enrichment process is called eutrophication. The addition of nutrients promotes the growth of aquatic life. These creatures survive, grow and die. Their debris rots in the pond and the nutrients necessary to raise them are returned into the water of the pond to keep them circulating. However, material that resists spoil will eventually accumulate and the pond will fill up

If the water contains a large amount of suspended particles or organic matter, the composition of water may be blurred. The bottom of the pond is usually sand, putrefying substance, microbial sediment. The water in the pond is usually stagnant. Nutrients enter the pond through the stream, either lost in the rain or melt the snow from the surrounding terrain. It pours soil, animal waste, and decaying plant matter into a pond where it is broken down and supplies fuel to the ecosystem of the pond. Many people living in the surrounding area, migratory birds and animals near plants use these ponds to supply abundant nutrients and water.

Ponds are an excellent source of microorganisms and can be easily seen at correct magnification. Pick up some water in the bottle and check the water with a magnifying glass or microscope. How many kinds of microorganisms can you see? Compare the type of microorganisms in the upper part of the pond and the type of microorganisms in the lower part of the pond. Why are microbes near the surface different from deep microorganisms?
