- Abiotic and Biotic Factors in an Ecosystem . An ecosystem consists of the biological community of living organisms (biotic) and non-living organisms (abiotic) that occurs in a specific locale, and the physical and chemical factors that make up the environment.

NUTRIENTS Nutrients are those organic and inorganic compounds that a living organism must acquire from the environment to support essential life processes, including basal metabolism, growth and maintenance of body tissues, activity, reproduction, and maintenance of general health.

Ecology (populations,energy,cycles) 1 The ultimate fate of energy in ecosystems is for it to be lost as heat. 2  Energy and nutrients are passed from organism to organism through the food chain as one organism eats another. 3  Decomposers remove the last energy from the remains of organisms.  Inorganic nutrients are cycled, energy is not.

Ocean Ecosystems: Open Ocean Organisms are also more abundant where there are more nutrients: in the neritic, where nutrients wash off the land, and in upwelling zones, where relatively cold nutrient-rich waters from the deep ocean rise to the surface. Pelagic life is dominated by plankton, mostly tiny organisms that move with water currents.

- In these next sections, we will look at how communities interact with a few other abiotic factors: the essential chemicals water, carbon, nitrogen, and phosphorous. Water is perhaps the most important component of any ecosystem. All living organisms need water to grow and survive. In an ecosystem, water cycles through the atmosphere, soil, rivers, lakes, and oceans. Some water is stored deep in the earth. Surface water, on the other hand, is the source that sustains life on land. In many cases, water also structures the physical habitat of an ecosystem. Polar bears, for example, rely on ocean ice in order to successfully hunt and capture seals.

The Carbon Cycle You might not find a fish for your ecosystem easily. If you do, make sure it is small (about ½-1 inch). A very small crayfish will also work. Snails will likely be found on rocks near shore or on decaying leaves. You only need two or three. Remember that you are taking organisms from a living ecosystem to put in your ecosystem.

Ecological interactions Plants, algae, and microscopic organisms such as phytoplankton and some bacteria, make energy-rich molecules (in other words, their food) from sunlight, water, and carbon dioxide during the process called photosynthesis (“photo” means “light, and “synthesis” means “to make” – photosynthesizers are using sunlight to make food).

A nutrient is a chemical that an organism needs to live and grow or a substance used in an organismâs metabolism which must be taken in from its environment. They are used to build and repair tissues, regulate body processes and are converted to and used as energy. Methods for nutrient intake vary, with animals and protists consuming foods that are digested by an internal digestive system, but most plants ingest nutrients directly from the soil through their roots or from the atmosphere. Organic nutrients consist of carbohydrates, fats, proteins (or their building blocks, amino acids), and vitamins. Inorganic chemical compounds such as dietary minerals, water (H2O), and oxygen may also be considered nutrients.

Unit 4: Ecosystems // Section 3: Energy Flow Through Ecosystems Unit 4: Ecosystems // Section 3: Energy Flow Through Ecosystems. Ecosystems maintain themselves by cycling energy and nutrients obtained from external sources. At the first trophic level, primary producers (plants, algae, and some bacteria) use solar energy to produce organic plant material through photosynthesis.

Plant nutrition Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.

Mineral (nutrient) Plants absorb dissolved elements in soils, which are subsequently ingested by the herbivores that eat them, and the elements move up the food chain. Larger organisms may also consume soil (geophagia) or use mineral resources, such as salt licks, to obtain limited minerals unavailable through other dietary sources.

Ecosystem in a bottle project Ecosystem in a bottle project. In order for any ecosystem to continue a balance between three main components must be maintained. Nutrients must be converted into a usable form for the organisms in the ecosystem. This process starts through photosynthesis which uses light to take raw materials and convert them into carbohydrates.

Ecological interactions Some organisms have the amazing ability to make (produce) their own energy-rich food molecules from sunlight and simple chemicals. Organisms that make their own food by using sunlight or chemical energy to convert simple inorganic molecules into complex, energy-rich organic molecules like glucose are called producers or autotrophs.

- Many international studies state that botanical species utilized for phytodepuration must have a high capacity to absorb nutrients. The most suitable species are emergent macrophytes. These are aquatic plants growing in wetlands, shallow lakes, and streams and that are either emergent, submergent, or floating.

Ecosystem As ecosystems age this supply diminishes, making phosphorus-limitation more common in older landscapes (especially in the tropics). Calcium and sulfur are also produced by weathering, but acid deposition is an important source of sulfur in many ecosystems.
