Ecosystems #Ecoflow #TackkThursday
Types of ecosystems//
1. The Forest Ecosystem// These are the ecosystems where abundance of flora (plants) is seen and they have a large number of organisms living in relatively small areas. Therefore, the density of life in forest ecosystems is very high. Any small change in the ecosystem can affect the whole balance and collapse the ecosystem. You can see wonderful diversity in the fauna of these ecosystems too.
2. The Desert Ecosystem// Desert ecosystems are found in regions receiving an annual rainfall of less than 25cm. They occupy around 17 percent of all land on the planet. Due to very high temperature, intense sunlight and low water availability, flora and fauna are very poorly developed and scarce. Vegetation is mainly bushes, shrubs, few grasses and rarely trees. Leaves and stems of these plants are modified to conserve water. The best known desert plants are the succulents like spiny leaved cacti. Animal life includes insects, reptiles, birds, camels all of whom are adapted to the xeric (desert) conditions.
3. The Grassland Ecosystem// Grasslands are found in both temperate and tropical regions of the world but the ecosystems are slightly varying. This area mainly comprises of grasses with very little amount of shrubs and trees. Main vegetation is grasses, legumes and plants belonging to composite family. Many grazing animals, herbivores and insectivores are found in grasslands.
4. The Mountain Ecosystem// Mountain lands provide a scattered but diverse array of habitats in which a large range of plants and animals are found. At higher altitudes harsh environmental conditions generally prevail, and only treeless alpine vegetation is found. The animals living here have thick fur coats fro prevention from cold and hibernate in winter months. Lower slopes commonly are covered by coniferous forests.
5. The Marine Ecosystem// Marine ecosystems are the largest ecosystems with coverage of nearly 71% of the Earth's surface and containing 97% of the planet's water. The water in Marine ecosystems has salts and minerals dissolved in them in high amounts.
Decomposer// The fungus is a decomposer that breaks down dead organisms to use as nutrients.
Consumer// A Vulture is a consumer because they feed off of what other animals kill.
Ecosystem// An ecosystem is the interaction of many communities with the abiotic physical components of its environment.
Producer// A polar bear is a producer because they kill first, they produce what they eat.
Food Chain// Animals and plants are always invovled in a food chain.
Biotic// The three main groups of ecological factors are, climatic, physiographic and biotic.
Abiotic// Successful species are generally well adapted to their abiotic environment.
Adaptation// The conspicuous absence of Barn Owls from regions far North & South of the Equator is probably due to its poor adaptation to cold.
Examples of biotic factors in a wetland ecosystem// Crabs, fish, algae, seaweed, frogs, plants, alligators.
Examples of abiotic factors in a wetland system// Water temperature, dissolved water oxygen content, water ph, soil type, sunlight, rocks.
Energy enters the ecosystem food chain in what form?// Solar energy.
What do the arrows of the picture above represent?// The arrows of the picture above represent how the ecosystem flows and how and where that animal/organism fits into the food chain and what their role is.
What would happen to a food chain if one element was eliminated?// If a food chain loses an organism, it creates an imbalance and
disruption in the food chain. For example, if a species of bird
becomes extinct, the insect population can grow dramatically which
creates problems for other creatures.
How do wetlands positively affect water quality?// Wetlands have important filtering capabilities for intercepting surface- water runoff from higher dry land before the runoff reaches open water. As the runoff water passes through, the wetlands retain excess nutrients and some pollutants, and reduce sediment that would clog waterways and affect fish and amphibian egg development. In performing this filtering function, wetlands save us a great deal of money.
How do wetlands offer flood protection?// Wetlands function as natural sponges that trap and slowly release surface water, rain, snowmelt, groundwater and flood waters. Trees, root mats, and other wetland vegetation also slow the speed of flood waters and distribute them more slowly over the floodplain. This combined water storage and braking action lowers flood heights and reduces erosion. Wetlands within and downstream of urban areas are particularly valuable, counteracting the greatly increased rate and volume of surface- water runoff from pavement and buildings.
How do wetlands provide habitat for wildlife?// More than one-third of the United States' threatened and endangered species live only in wetlands, and nearly half use wetlands at some point in their lives. Many other animals and plants depend on wetlands for survival.
What other benefits do wetlands offer?// We use a wealth of natural products from wetlands, including fish and shellfish, blueberries, cranberries, timber, and wild rice, as well as medicines that are derived from wetland soils and plants. Many of the nation's fishing and shellfishing industries harvest wetland- dependent species; the catch is valued at $15 billion a year. In the Southeast, for example, nearly all the commercial catch and over half of the recreational harvest are fish and shellfish that depend on the estuary- coastal wetland system.
