The structure of an ecosystem is related to its species diversity. Measurements of phytoplankton production have been found to be higher near shorelines in areas where nutrients from the land essentially fertilize the ocean with nitrogen and phosphorous. They make sure that not only their forest ecosystem is inhabitable, but that creatures that rely on oxygen can live all over the world. In the tropics, they are epiphytes, which means that they grow on another tree without harming it. A system formed by the interaction of all living organisms with each other and with physical and chemical factors of the environment in which they live, all linked by transfer of energy and material, is called an ecosystem. An arid desert ecosystem does not have a consistent water supply, so its primary producers, such as algae and lichen, spend some periods of time in an inactive state. The average net primary productivity of this woodland ecosystem is substantially lower than the average net primary productivity of a swamp ecosystem. Forest ecosystems are one of the terrestrial ecosystems. After a rain, algae and lichens become photosynthetically active and (due to their ability to reproduce rapidly) provide a food source for higher-level organisms before the desert heat causes the water to evaporate. The melting of sea ice in the spring along with the increased availability of sunlight triggers algae production in the Arctic region. Producers make food from the sun. Consumers. Biotic components comprise of producers, consumers, and decomposers. (a); 10. Mosses represent an evolutionary step-up from algae. The best examples of producers are plants, lichens and algae, which convert water, sunlight and carbon dioxide into carbohydrates. The zone of a sea lying over the continental shelf is known as the: 39. They also may settle on whale carcasses and even shipwrecks, which act as a source of organic material. They are classified as bryophytes, which means, unlike algae, they have true roots, stems, and leaves. A few examples of terrestrial ecosystems are listed below:a. Grassland Ecosystemsb. Q.3. The flow of energy is always unidirectional. Increase in fauna and decrease in flora would be harmful due to an increase in: 43. In this process of eating and being eaten, nutrients are passed from one step to the next in a food chain. At these points, the ecosystems are interdependent.
