An ecosystem, a term frequently used in biology, is a community of plants and animals connecting with one another in a given region, and furthermore with their non-living environments. The non-living environments consist of climate, earth, sun, soil, atmosphere and air. The ecosystem identifies with the way that all these various living beings live close to each other and how they interact with each other.

Freshwater ecosystems are a subset of Earth's oceanic ecosystems. They include lakes and ponds, rivers, streams, springs, bogs, and wetlands. They can be appeared differently in relation to marine ecosystems, which have a bigger salt substance. Freshwater habitats can be characterized by various elements, including temperature, light penetration, nutrients, and vegetation.

These would be able to be separated into littler ecosystems, let’ take a look at the smaller parts of the ecosytem:

Pond ecosystems – These are generally moderately small and contained. More often they include numerous sorts of plants, amphibians and insects. Now and again they include fish, yet because these can't move around as effectively as amphibians and insects, it is less likely, and more often fish are artificially presented to these environments by people.

Setting off just before dawn, we hiked the short 1km trail up to the top of Raven Crag, which overlooks the length of Thirlmere. It was one of those bitingly cold winter mornings, but the moment the sun came up over the Helvellyn range, all discomforts are forgotten as you realise the beauty of the world.

River ecosystems – Because rivers consistently connect to the ocean, they are bound to contain fish alongside the usual plants, amphibians and insects.

These sorts of ecosystems can likewise include birds since birds frequently chase in and around water for little fish or insects.

Freshwater ecosystems are those that are contained to freshwater environments. This includes, but isn't restricted to, ponds, rivers and different watercourses that are not the sea (which is, obviously, saltwater and can't support freshwater animals for long). Freshwater ecosystems are really the littlest of the three key classes of ecosystems, representing only 1.8% of the whole of the Earth's surface. The ecosystems of freshwater systems include moderately small fish (greater fish are generally found in the sea), amphibians, (for example, frogs, toads and newts), insects of different sorts and, obviously, plants. The totally littlest living piece of the food web of these sorts of ecosystems is plankton, a little living being that is frequently eaten by fish and other little creatures.
