In most cases, primary producers use photosynthesis to make food, so sunlight is a necessary factor for their environment. However, sunlight cannot reach deep areas in caves and in the depths of the sea, so some primary producers have adapted to survive. Primary producers in these environments use chemosynthesis instead. 2. Which of them is a primary producer? A. Brown algae B. Flowering plants C. Chemotrophic bacteria D. All of the above producers are organisms capable of producing simple carbohydrates such as glucose from gaseous carbon dioxide.
This process of producing organic molecules from inorganic carbon sources is called primary production. The energy for this process can come from solar radiation, chemical reactions or heat in deep-sea geothermal sources. On land, most growers are plants. Marine production is dominated by algae and plankton. We do our best to ensure that our content is useful, accurate and secure.

Sunlight cannot reach the deep seabed, but primary producers still thrive there. In these places, microorganisms congregate in areas such as hydrothermal vents and cold springs, where they draw their energy from the metabolism of surrounding inorganic materials, such as.B chemicals that seep from the seabed rather than sunlight. You can also settle on whale carcasses and even wrecks, which serve as a source of organic matter. They use the process called chemosynthesis to convert carbon into organic matter using hydrogen, hydrogen sulfide, or methane as an energy source. The terrestrial or soil-based food chain consists of a variety of different organisms, ranging from microscopic single-celled producers to visible worms, insects and plants. The main producers are plants, lichens, mosses, bacteria and algae.
Primary producers of a terrestrial ecosystem live in and around organic matter. Since they are not mobile, they live and develop where nutrients are present to support them. They take nutrients from the organic matter left in the soil by decomposers and convert them into food for themselves and other organisms. Like their aquatic counterparts, they use photosynthesis to convert soil nutrients and organic matter into food sources to feed other plants and animals. Because these organisms need sunlight to process nutrients, they live on or near the soil surface. It was a soap opera in the Senate about none other than a soap opera producer. The appearance of phytoplankton would have contributed to a great evolutionary explosion 250 million years ago. After a mass extinction at the end of the Paleozoic, an increase in nutrients and a reduction in predation allowed these plants to multiply in the oceans. Their abundance and improved nutrient content have also allowed primary consumers such as zooplankton to reproduce. As these groups of organisms developed and colonized larger ocean areas, some populations diversified, adapting to new environments, ultimately resulting in a dramatic increase in ocean biodiversity. Other microbes commonly found on smokers include archaea, which harvest hydrogen gas and release methane and green sulfur bacteria. This requires both chemical energy and light energy, the latter obtained from the luminous radioactive glow emitted by rocks heated by geothermal energy.
Many of these lithotropic bacteria form mats around the vent that are up to 3 centimeters thick and attract primary consumers (grazing animals such as snails and scaleworms), which in turn attract large predators. A dry desert ecosystem does not have a constant water supply, so its main producers such as algae and lichens spend some time in an inactive state. Rare rains result in short periods of activity during which organisms act quickly to produce nutrients. In some cases, these nutrients are then stored and released slowly in anticipation of the next rainfall. It is this adaptation that allows desert organisms to survive in the long term. These poikilohydric plants, found on soils and stones, as well as some ferns and other plants, can alternate between active and dormant phases, depending on whether they are wet or dry. Although they seem dead when dry, they are actually in a dormant state and transform with the next rainfall. After a rain, algae and lichens become photosynthetically active, providing (due to their ability to multiply rapidly) a food source for higher-level organisms before desert heat causes water to evaporate. .
