List two human made ecosystem

Term Meaning Habitat loss A reduction in liveable space and resources within an ecosystem Pollution The introduction of a harmful substance or other disruptive component into the environment Invasive species A non-native species that becomes established in an area and causes harm to native communities Overexploitation of resources The human consumption of natural resources at a rate greater than what the environment can support or replenish Climate change A long-term shift in typical regional or global weather patterns, often attributed to global warming Advances in technology have allowed humans a unique advantage over any other species on the planet: the ability to overcome the stresses of global carrying capacity, or the limit to the number of individuals the planet can support. As a result, human populations continue to grow. This population growth means that humans use more and more resources, which has significant implications for the health of Earth’s ecosystems. Pollution occurs when harmful substances enter the environment. Examples of pollutants include disruptive light or noise from human activities, or harmful chemical wastes. For example, the nitrogen in fertilizer runoff can induce the rapid overgrowth of algae in oceans. These algal blooms choke the surrounding waters of available oxygen, resulting in dead zones, or nutrient-depleted regions that can't support plant or animal life. • Invasive species are species that have become established in a new environm...

Difference between Natural and Artificial Ecosystem Natural Ecosystem Artificial Ecosystem Definition It is a naturally occurring ecosystem where organisms and the environment interact with each other to co-exist. It is a human-made ecosystem with biotic and abiotic components, and also involves some technology. Examples Rainforests, seas, lakes, grassland, etc Zoos, poultry farms, aquariums, etc Survival It can survive on its own. It needs human assistance to flourish. Genetic diversity It has a vast genetic diversity. Since it is human-made, it has very limited genetic diversity. Evolution The living organisms in this type of ecosystem have a high chance of evolution as they learn to adapt to their surroundings. It has a very low chance of evolution. Food chain The food chain is long and complex. Food chains are short and usually incomplete. Nutrient cycles The nutrient cycles are complete and run naturally. The nutrient cycles are always incomplete. Importance These ecosystems ensure the conservation of natural resources, give beauty to the surroundings, and allow biological inheritance to the next generations. These ecosystems are made by man for their own use, such as for high productivity and entertainment purposes. Explore Also read: • • • • •

(i) Ecosystem • The ecosystem is the functional unit in the environment where the biotic or living organisms interact with the abiotic or nonliving components in an area. • Two components of an ecosystem are: biotic (living) and abiotic (nonliving). • These two components constantly interact with each other in an ecosystem • The ecosystem can be of different types. Examples include pond ecosystem, forest ecosystem etc. Components: • Biotic: The living organisms of the ecosystem include producers, consumers, and decomposers • Abiotic: The nonliving component of the ecosystem includes the physical environment such as soil temperature, water, climate, air. (ii) Types of ecosystems: • Two main types are; natural and artificial ecosystems • Natural ecosystems exist in nature where there is no role of the human in its regulation. An example is the pond ecosystem. • Artificial ecosystems are created by humans for their benefit. They are regulated by humans. Difference between pond and aquarium: • The pond is a natural ecosystem, therefore, is self-sustaining. • The aquarium is not self-sustaining and requires the supervision of humans to keep it functional. Without the regulation by humans, these will become nonfunctional. • The pond can clean itself through various microorganisms whereas the aquarium cannot. • The accumulation of the waste inside the aquarium will cause harm to the fishes and other organisms since the excreta of fishes will stay inside the water only.

Image Sidewinder in Desert Species are not only adapted other living things within their ecosystems but also to the abiotic factors—nonliving physical and chemical aspects—in their environments. The sidewinder's characteristic movement style is an efficient way for it to move. Photograph from age fotostock Animals walk, crawl, and slither over most of Earth, and plants thrive in places ranging from prairies to the bottoms of ponds. This abundance of life is possible because of many abiotic factors, which are the nonliving physical and chemical aspects of an ecosystem. Abiotic factors are a bit like the Little Bear's porridge in the Goldilocks' story—they have to be just right in order for life to flourish. Many animals also require a particular set of abiotic factors to thrive. Imagine a snake living in the Arizona desert. It is right at home in that dry landscape because it is able to move through loose soil and sand by twisting its body. It can also avoid the heat by hiding under rocks. Some snakes are also nocturnal—that is, they hunt and move around mostly during the night when the sun is not shining. Now imagine that someone picks up one of these desert-adapted snakes and places it on a snowy peak in the Himalayas. The Himalayas lack the abiotic factors—like an arid climate and loose soil—that the snake is adapted to, and the snake likely will not be able to survive. Humans, like other animals, also require certain abiotic factors to survive and live comfortably. For ...

Every living thing on Earth needs water to survive, but more than 100,000 species, including our own, need a special kind of water that can only be found in certain places and is in very rare supply: freshwater. The plants, animals, microbes, rocks, soil, sunlight, and water found in and around this valuable resource are all part of what is called a freshwater ecosystem. Less than three percent of our planet’s water is freshwater, and less than half of that is available as a liquid; the rest is locked away as ice in polar caps and glaciers. For these reasons, freshwater ecosystems are a precious resource. Where is Freshwater? Freshwater starts out as water vapor that has evaporated from the surface of oceans, lakes, and other bodies of water. When this vapor rises, it leaves salts and other contaminants behind and becomes “fresh.” The water vapor collects in drifting clouds that eventually release the water back to Earth in the form of rain or snow. After freshwater reaches the ground through precipitation, it flows downhill across a landscape called the watershed to lakes, ponds, rivers, streams, and wetlands. But freshwater can be found in less-obvious places too. More than half of all freshwater on our planet seeps through soil and between rocks to form aquifers that are filled with groundwater. The top surface of an aquifer is called the water table, and this is the depth where wells are drilled to bring freshwater into cities and homes. Studying Freshwater Ecosystems ...
