The first link in every food chain is a primary producer. The primary producer converts inorganic compounds, such as carbon dioxide and water, into organic compounds that can be used as energy. Producers can be photosynthetic or chemosynthetic, depending on the source of energy they use to make their food.Know More
In photosynthesis, a photosynthetic producer uses the light of the sun to convert carbon dioxide and water into glucose, a sugar that can be used as energy. A chemosynthetic producer uses the energy from compounds, such as those containing sulfur, to make their own food. The ultimate product of both photosynthesis and chemosynthesis is sugar, the energy currency of organisms.
Many of the producers in ecosystems are green plants. Chemosynthetic producers tend to live in environments that are not conducive to life, such as deep sea vents and hot springs.Learn more about Environmental Science
According to Nature.com, the golden eagle is at the top of the food chain, above plants, squirrels and scorpions. Plants are considered primary producers and make up the first level of the food chain. Ground squirrels, which are primary consumers, are in the second level and feed on plants. Golden eagles are tertiary consumers, meaning that they prey upon primary and secondary consumers.Full Answer >
Seahorses occupy a middle position in their food chain. They are carnivores that feed on tiny crustaceans, such as shrimp. The shrimp feed on algae, which are near the base of the food chain. Seahorses are preyed upon by crabs and fish, which are eaten by larger fish. These large fish are hunted by apex predators, including sharks that are at the top of the food chain.Full Answer >
Primary producers, or autotrophs, make up the first trophic level of all food webs. Autotrophs are organisms that produce their own energy from inorganic substances, such as carbon dioxide and water. The primary producers of many food webs are green plants.Full Answer >
A food web is a comprehensive map of how energy moves, in the form of food, throughout an ecosystem, while a food chain is one specific path through the web. Most food webs on Earth derive their energy primarily, if not exclusively, from sunlight. That energy is captured by plants via photosynthesis and then distributed to the consumers in the environment.Full Answer >
