Full Answer
Producers in an ecosystem provide food and nourishment for other species. For example, green plants self-feed via photosynthesis and then grazing animals use the plants for their own nourishment. Photosynthesis is a process in which an organism uses inorganic carbon to synthesize organic compounds using...
Primary producers include everything from microscopic plants of the oceans to the giant redwoods of California. Primary production is influenced by the availability of nutrients.
In summary, producers are organisms that make their own food. Producers create food for themselves and also provide energy for the rest of the ecosystem. Any green plant, like a tree or grass, as well as algae and chemosynthetic bacteria, can be producers.
Collectively, ecological processes produce organic matter, transfer carbon and nutrients, drive soil formation, and enable organisms to reproduce.
Producers are able to make their own food and do not rely on the ecosystem for nourishment. Examples of producers include photosynthetic microbes and plants.

Photosynthesis is a process in which an organism uses inorganic carbon to synthesize organic compounds using solar energy or light. Autotrophs are a producer because they too create their own food via inorganic substances, such as carbon dioxide. The consumers who feed on producers are heterotrophs. ADVERTISEMENT.
Ecological processes such as primary production, respiration, energy, carbon and nutrient flow through food webs, reproduction, and decomposition are represented as rates of change, which requires repeated measurement over time. This is difficult to achieve for many ecosystems at a local scale and even more difficult at the national scale.
Primary producers include everything from microscopic plants of the oceans to the giant redwoods of California. Primary production is influenced by the availability of nutrients. If primary production declines, energy flow to higher trophic levels is diminished, potentially compromising the sustainability of animal populations dependent on plants ...
Ecological systems are sustained by a number of biological, physical, and chemical processes, including primary production (conversion of the sun's energy into organic matter through photosynthesis), and the associated cycling of carbon, nutrients (nitrogen, phosphorus), hydrogen/oxygen, and other elements from the physical environment (air, water, land) through biological organisms and back into the physical environment. #N#Collectively, ecological processes produce organic matter, transfer carbon and nutrients, drive soil formation, and enable organisms to reproduce. They also play an important role in providing ecological services—for example, providing natural resources, such as food, fiber, and timber, and regulating air and water quality. 1 Ecological processes, such as primary production, influence the extent, distribution, and biodiversity of systems.

With respect to natural forces, ecological processes are affected by both small-scale natural events such as seasonal changes in temperature, precipitation, and stream flows and large-scale events such as ...
Changes in land use that alter the extent and distribution of ecological systems can directly affect ecological processes in particular areas, often causing associated changes in ...
EPA has long been concerned with the impacts of human activities—including pesticide use, chemical use, waste generation, land use changes, and water quality management, among others—on the rates, types, and timing of ecological processes.
