Question

write paragraph on 'balence in an ecosystem

Answer 1

The Earth hosts a vast network of ecosystems, from tiny tide pools to broad deserts to polar ice shelves. An ecosystem is defined as the habitat in which animals, plants, and microorganisms interact with non-living factors such as landscapes and temperature. Balanced ecosystems maintain a flow of materials and energy. In a balanced ecosystem, an interdependence of each factor exists. Any waste materials can be used by living animals, plants and animals.
A balanced ecosystem represents a sustainable habitat of interdependent animals, plants, and microorganisms and their environment. Balanced ecosystems display efficient energy and material cycling and interconnectedness between primary producers and predators.

Factors of Balanced Ecosystems
In a balanced ecosystem, the community of living (biotic) organisms interacts with non-living (abiotic) features in the environment. Abiotic features of ecosystems include precipitation, temperature, landscape, sunlight, soil or water chemistry, and moisture. The types of biotic factors in a balanced ecosystem include primary producers such as plants, primary consumers such as herbivores, secondary consumers such as carnivores, consumers such as omnivores that consume both plants and animals, and detritivores that eat decaying organic matter. Biotic factors rely upon abiotic factors to survive. Plants require certain temperature, moisture and soil chemistry to thrive. Animals rely on those plants for their food. Anything affecting any factor of an ecosystem can throw it off balance and force organisms to adapt or die off.

Energy and Material Cycling
A balanced ecosystem works via energy and material cycling. The chief energy source of ecosystems is sunlight. Photosynthesis of sunlight by plants creates oxygen as a waste product, which in turn is used in respiration by animals. Animals, in turn, create carbon dioxide as waste, and that is used by plants. The smallest organisms, microorganisms, decompose dead plants and animals into nonorganic material via enzymes. The conversion of the sun’s energy to chemical energy for photosynthesis or respiration results in energy loss as heat. Balanced ecosystems require the sun’s energy to exist and perpetuate the energy cycle.

Predators and Prey
Healthy ecosystems work within a balance of predator and prey relationships and their interactions with the environment. Ecosystems can have both a top-down, or predator-related, control on function, or a bottom-up control reliant on primary producers such as vegetation. Top-down control by a predator means that more predators lead to fewer grazers. This would lead to more primary producers because the grazers would be diminished. For bottom-up scenarios, primary producers drive ecosystem function in the presence of increased nutrients. When a top predator is removed from an ecosystem, the entire food chain in turn becomes affected. Populations of primary consumers (prey) animals increase, leading to greater competition for food in the form of primary producers. One such example is the hunting of sea otters by humans, which led to kelp forest ecosystem collapse in the Aleutian Islands. Sea urchins overtook the kelp forests. Once sea otters returned to predate the sea urchins, the kelp ecosystem returned to balance.

Answer 2

An ecosystem is balanced when the natural animals and plants and non living components are in harmony that there is nothing to disturb the balance.with increasing population,change in migratory patterns,and rise of human population,many ecosystems are in danger of losing that harmony.
