Abiotic/Biotic Factors

freshwater ecosystem abiotic factors

The young fish swim down the river to the ocean, where they grow to maturity. Invertebrates such as zooplankton, molluscs, crustaceans and insects consume nutrients from the primary producers and pass it on to the next level of consumers, namely, the vertebrates such as fish. The visible result of these rotations, which can be seen in any lake, are the surface foamlines that run parallel to the wind direction. Animals living in the ocean all have special adaptations that allow them to survive in high salt concentrations. Biotic factors are the living components that affect a marine organism.

Freshwater Biome (Lakes and Rivers) by Melissa Johnson on Prezi

To close the lesson, have students identify several lentic and lotic ecosystems in the local area. The abundance of various phytoplankton species varies in relation to their biological need for these nutrients. As the summer begins, two distinct layers become established, with such a large temperature difference between them that they remain stratified. Biotic factors include the living parts of the ecosystem, including animals, plants and microorganisms. They produce sugars and oxygen from sunlight, carbon dioxide and abiotic nutrients.

Abiotic and Biotic Factors

All energy lost is turned into heat. Lentic waters range from to to , and much of this article applies to lentic ecosystems in general. Rivers are also home to these animals, but may contain very different species that can handle the fast-moving water. Chemistry including pollutants, pH, and salinity factors like fresh water influx with solutes and sediments. The chemical factors, on the other hand, include chemical properties, like the pH level of water, pollutants in the water body, etc. Note: Sometimes, lentic ecosystems are differentiated from wetlands, which are areas that are wet or covered with water for at least part of the year, with seasonal variations of water depth, sometimes including dry periods when there is no water at the surface.

Aquatic Biomes

The water is as clear as it is near the source since phytoplankton can be suspended in slow-moving water. Abundant plankton serve as the base of the food chain for larger animals. The water here contains silt, is well-oxygenated, low in pressure, and stable in temperature. Even if the water in a pond or other body of water is perfectly clear there are no suspended particles , water, on its own, absorbs light. Here, some organisms use chemicals from the ocean floor to produce food instead of using sunlight like their counterparts in shallow waters.

Similarly, the great deal of diversity that you get to see in the animal species of this biome can be attributed to the fact that all of them have resorted to certain adaptations in order to survive in these freshwater sources. Plants, animals, fungi, protist and bacteria are all biotic or living factors. There are three types of symbiotic relationships, parasitic, mutualistic, and commencialistic. In Freshwater, there are many predatory relationships. For example river birches, willow trees, water stargrass, water lilies, duckweed, cattails, reeds, and tapegrass all grow by water. Those that can are often red in color due to the presence of large amounts of , which greatly increases the amount of oxygen carried to cells.

Freshwater Biome Abiotic Factors

While there are some abiotic and biotic factors in a terrestrial ecosystem that might obscure light such as fog, dust, or insect swarms , usually these are not permanent features of the environment. Photosynthesis occurs primarily in algae growing on rocks since the swift current in channels inhibits the growth of phytoplankton. Corals evolved to survive at the upper limit of ocean water temperature. The ocean is categorized by several areas or zones. A variety of strategies are provided to meet the needs of students with different learning styles. The animal is endangered because of hunting, calf mortality, climate change, and habitat loss. Apex predators are large predators with no predators of their own.

Aquatic Biomes

The organism is endangered because of hide hunting, pollution, loss of habitat, and removal of adults for commercial farming. Younger rivers cut a straighter and direct path through the ground and rock. Phosphorus enters lentic waters from effluents, discharge from raw sewage, or from runoff of farmland. Precipitation maintains and creates freshwater biomes when water runs over the surface of land and flows back to rivers or lakes. These are the factors that cause a deep ocean to be totally different from a shallow lake. In biology, abiotic components are the non-living components of the ecosystem which affect the living components which exist there. During the winter, the temperature at the bottom can be 4° C while the top is 0° C.

Abiotic Factors Abiotic factors fall into four main categories, which are climatic factors, edaphic factors, organic substances and inorganic substances. Objects with neutral buoyancy tend to be evenly distributed in the water column. For instance, leeches have elongated bodies and suckers on both ends that attach to the substrate, keeping the leech anchored in place. Biotic Factors Insects: Insects are important part of the environment. In fact, 71% of Earth's surface is water, so the aquatic ecosystems found here are a big part of the cycle of life. Weather patterns wind and water currents.

Human activities causes terrestrial biomes to differ; human agricultural development and logging; biomes are markedly different mainly affected are temperate grass lands, tropical rainforest. Several species of insects are found in this biome, like mosquitoes and dragonflies. Examples: freshwater aquatic, saltwater aquatic, desert, forest, tundra, and grasslands. Many of them, such as huckleberries and blackberries, also have small, sweet fruits and berries. Abiotic Factors of Lakes Lakes are large bodies of water on the surface of the earth. Animals that can maintain relatively constant internal temperatures endotherms can live in a wide range of external temperatures, whereas ectotherms, which rely on the external environment are more restricted to the temperature they can survive in.
