Structural components are the living and the long living things in an ecosystem, or can be called biotic and a-biotic components in an ecosystem. The a-biotic components in a pond ecosystem include, water, light and soil…

The beginner of the pond ecosystem is sun. Producers use sunlight and convert carbon dioxide and water into organic compounds and oxygen through a process called photosynthesis. Other most important nutrition for plants is nitrogen and phosphorus. Wandering plants or the phytoplankton (Volvox, Oscillatoria, Diatoms, Spirogyra, Zygnema, Hydrodictyon, Desmids, etc) go through the process of photosynthesis and release oxygen in the water which can be used by bacteria and animals in the pond. Likewise, the Periphytic algae (attached to the rocks and other substances) carry out photosynthesis and provide oxygen in the bottom of the pond so the decomposers can use it. The submerged plants and the Floating plants (Nelumbium, Nymphea, Blixa, Eicchornia, Pistia etc) provide oxygen to the pond and the emergent plants, to the environment outside the pond. This is the first level. Herbivores and carnivorous belong to the second level and are called consumers. Herbivores feed on plants and get energy whereas the carnivores feed on herbivorous and get energy. But whenever an animal or a plant is not consumed by any other animal, that matter is decomposed by decomposers, which are on the 3rd level. The tissues are broken down into much simpler compounds which are again used by the plants for nutrients. As energy is converter, some of it is released in the form of heat in the water to maintain the inner functions of the cells in every organism. Nutrient cycle Carbon, nitrogen, and oxygen are really important for a cell. The process through which these substances pass from on organism to another or from on cell to the other is called nutrient cycle. Change over time The health of an ecosystem can be endangered by several changes over time. If specie is killed in the pond, it can be highly dangerous for other living in the pond as many animals might feed on that specie for nutrients and the whole system might crash. Due to the climate change, excessive heat in the environment, drought can appear killing all the species living there. The growth of thick trees around the pond can block the passage of sunlight to the pond, resulting in death of plants and thus the animals. Besides this, natural succession can occur which can totally change the biotic community. It actually occurs due to the changes in the plants, animals or other a-biotic factors, and so a new eco cycle can begin How humans may have affected biogeochemical cycles in that ecosystem. There are many ways a human might affect the pond ecosystem. Nitrogen cycle affected: During transportation, ammonia is released in the atmosphere, which is absorbed in the pond. Fertilizers are highly harmful for the fishes as it contains nitrites and nitrates and thus can affect the nitrogen cycle. Ammonia is extremely toxic to fish and should be removed or converted into harmless matter. If the level of ammonia increases in the pond, fishes can die. New agricultural practices have highly disturbed the nitrogen cycle of the pond. In order to fulfill the agricultural demands for food, there is an extensive usage of nitrogen gas in the green house which enters the pond through different means. Carbon cycle affected: Accumulation of Carbon dioxide in the pond is highly dangerous for the fish species living in it. If the carbon dioxide amount is high in the pond, it would be difficult for the fishes to remove their internal carbon dioxide in the water, resulting in accumulation in fish blood. This inhibits and endangers the ability of hemoglobin in the fish blood, and thus causes suffocation for fishes.

Ozone is made up of three atoms of oxygen which is poisonous when people inhale it especially at high concentration. It is unlike the air human beings need which is made up of two atoms of oxygen. People may get sick especially the disease called asthma when ozone is formed near the surface of the earth. It is very useful once it is formed in the atmosphere because it serves as a blanket of protection from solar radiation.
The park comprises biotic factors, such as native forest plants, birds, insects and decomposers, whereas abiotic factors include stones, soil, dead tree logs, and minerals in the soil (Nadakavukaren, 2011). The ecological dormant in Hyde Park are the native forests which constitute the greatest biomass in the micro-ecosystem.
Abiotic components comprise of chemical and physical things present in an environment. Biotic components comprise of the living things, for instance; plants and animals. Joshua Tree National Park is an example of a natural ecosystem that supports the existence of a variety of rare trees, as the name suggests, and a variety of wildlife.
This high percentage is attributed to the process of photosynthesis, which utilizes the CO2, solar energy water, and chlorophyll, an essential component of the respiration of eukaryotes. Interaction of biotic and abiotic components together with biotic-biotic interaction is responsible for the proliferation of life.
Organisms such as mosses and ferns will first appear on that bare rock. After awhile, larger organisms, such as shrubs and trees, begin to grow.

Thus, it is important to understand and study the role of environmental factors in altering this genomic structure of an organism to actually see if these environmental factors lead to inherited changes. To study the role of these environmental factors, the factors must be identified, classified and justified.
The main source of energy in any ecosystem is the sunlight. Every ecosystem consists of certain components- the producer, the consumer, the non-living matter and the decomposers. If any one or more of the components are not present in an
In secondary production, the main source of energy is the heterotrophs. They produce the chemical energy and the herbivores feed on them. Energy flows through the species in a cycle that is dependent of each other.

There are many views that were developed by 16th and 17-century philosophers on nature and science. All of the associations and correspondences were developed with the thought that there was a universe with a hell and heaven as the polar opposites. These viewpoints were basically cultural, psychological and even biological.
