Heart 2: Changing Lifestyles and Heart Health * Populations of organisms can be categorized by the function they serve in an ecosystem: producers make their own food (plants), consumers obtain food by eating other organisms (animals), and decomposers consume waste materials and dead organisms (bacteria and fungi).* Energy from the sun flows through ecosystems.

Ecology (populations,energy,cycles) To summarize: In the flow of energy and inorganic nutrients through the ecosystem, a few generalizations can be made: 1  The ultimate source of energy (for most ecosystems) is the sun. 2  The ultimate fate of energy in ecosystems is for it to be lost as heat.

Welcome to the Ocean Productivity Home Page Total net primary production on Earth exceeds 100 billion tons of carbon per year, and it plays a profound role in the global carbon cycle. Many people are surprised to learn, however, that roughly half of this productivity occurs in the oceans and is conducted by microscopic plants called phytoplankton.

"The Flow of Energy: Primary Production to Higher Trophic Levels""All flesh is grass."" - IsaiahThree hundred trout are needed to support one man for a year. The trout, in turn, must consume 90,000 frogs, that must consume 27 milliongrasshoppers that live off of 1,000 tons of grass.-- G. Tyler Miller, Jr., American Chemist (1971)" Photosynthesis stores energy, and respiration releases it for use in functions such as reproduction and basic maintenance. When calculating the amount of energy that a plant stores as biomass, which is then available to heterotrophs, we must subtract plant respiration costs from the total primary production.

Productivity (ecology) In ecology, productivity refers to the rate of generation of biomass in an ecosystem. It is usually expressed in units of mass per unit surface (or volume) per unit time, for instance grams per square metre per day (g m−2 d−1). The mass unit may relate to dry matter or to the mass of carbon generated.

- The leaf is the primary site of photosynthesis in plants. Primary producers are organisms in an ecosystem that produce biomass from inorganic compounds (autotrophs). In almost all cases these are photosynthetically active organisms (plants, cyanobacteria, protists and a number of other unicellular organisms; see article on photosynthesis).

At which level of the food web is the supply of energy the greatest? explain? The first trophic level of the food chain has the greatest energy supply of food because they use the sun's energy to create their own food. (They are the autotrophs.) Organisms in other levels simply consume other organisms and obtain the energy through consumption.

- The most productive ecosystems are fertile estuaries and marshes, coral reefs, terrestrial vegetation on moist alluvial deposits, and intensive agriculture, which can have productivities of 10-25 × 103 kcal/m2/yr. See also Carnivore; Ecological pyramids; Food chain/web; Herbivore.

Trophic Levels in a Food Chain: Definition & Explanation The first trophic level contains the greatest number of organisms and is comprised mainly of plants. The organisms in this layer are called primary producers because they get their energy from an abiotic source. Most primary producers get their energy directly from the sun.his lesson will explore the feeding relationships of organisms in an ecosystem, including food chains and food webs. The lesson will also investigate the different trophic levels of a food chain and give examples of species found at each level.

Net primary productivity The energy not used in this process is stored in plant tissues for further use and is called net primary productivity. About 40 to 85 percent of gross primary productivity is not used during respiration and becomes net primary productivity.

General Information Net primary production is the rate at which all the plants in an ecosystem produce net useful chemical energy; it is equal to the difference between the rate at which the plants in an ecosystem produce useful chemical energy (GPP) and the rate at which they use some of that energy during respiration.

Which aquatic ecosystems have the highest Net Primary Production? Which ecosystems has the highest average net primary productivity? In terms of NPP per unit area, the most productive systems are estuaries, swamps and marshes, tropical rain forests, and temperate rain forests

- These tend to be the most productive ecosystems in the world. Estimates of the southern coastal plain of the U.S. have topped 8000 gC/m2/y through the combined efforts of marsh grass, mud algae, and phytoplankton in the tidal creeks.

What was the first life form on earth? It is estimated that the first life forms on earth were primitive, one-celled creatures that appeared about 3 billion years ago. That's pretty much all there was for about the next two billion years. Then suddenly those single celled organisms began to evolve into multicellular organisms.

Productivity (ecology) Secondary production Secondary production is the generation of biomass of heterotrophic (consumer) organisms in a system. This is driven by the transfer of organic material between trophic levels, and represents the quantity of new tissue created through the use of assimilated food.

Biomass (ecology) An ecological pyramid is a graphical representation that shows, for a given ecosystem, the relationship between biomass or biological productivity and trophic levels. 1  A biomass pyramid shows the amount of biomass at each trophic level. 2  A productivity pyramid shows the production or turn-over in biomass at each trophic level.

Primary production The maps above show Earth's monthly terrestrial net primary productivity from February 2000 to December 2013. The data come from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite.

"Krill ""deposits"" transport atmospheric carbon to the ocean depths" Collectively, krill make up the single largest concentration of biomass in the oceans. At any one time, there are 400 million tonnes of them swimming about in every ocean of the world. Their place in the ecosystem is as the second tier in the food pyramid.

- An energy pyramid illustrates the trophic levels of organisms in an ecosystem. Energy pyramids start with the sun, followed by the trophic levels: producers (plants) on the bottom, primary consumers (herbivores) next, then secondary consumers (eat plants and meat) and then tertiary consumers (meat eaters) at the top.

- All freshwater ecosystems (lakes, rivers, ponds, streams, wetlands) are home to various life forms, often collectively referred to as the food chain or food web. The numbers and variety of living organisms in a freshwater food web are dependent on the productivity of the ecosystem.n the deeper, open-water areas, algae are the dominant green plants. Collectively, these plants form the base of the freshwater food web. Their conversion, through photosynthesis, of inorganic nutrients and minerals to living (organic) matter is called primary production.

LabBench Activity 1 Gross productivity = the entire photosynthetic production of organic compounds in an ecosystem. 2  Net productivity = the organic materials that remain after photosynthetic organisms in the ecosystem have used some of these compounds for their cellular energy needs (cellular respiration).
