Consumer (food chain) A consumer in a food chain is a living creature that eats organisms from a different population. A consumer is a heterotroph and a producer is an autotroph. Like sea angels, they take in organic moles by consuming other organisms, so they are commonly called consumers. Heterotrophs can be classified by what they usually ...
The food chain is an energy source diagram. The food chain begins with a producer, which is eaten by a primary consumer. The primary consumer may be eaten by a secondary consumer, which in turn may be consumed by a tertiary consumer. The tertiary consumers may sometimes become prey to the top predators known as the quaternary consumers.
The term food system describes the interconnected systems and processes that influence nutrition, food, health, community development, and agriculture.A food system includes all processes and infrastructure involved in feeding a population: growing, harvesting, processing, packaging, transporting, marketing, consumption, distribution, and disposal of food and food-related items.
Primary production is the production of chemical energy in organic compounds by living organisms. The main source of this energy is sunlight but a minute fraction of primary production is driven by lithotrophic organisms using the chemical energy of inorganic molecules. Regardless of its source, this energy is used to synthesize complex organic ...
Food web. A freshwater aquatic food web. The blue arrows show a complete food chain ( algae → daphnia → gizzard shad → largemouth bass → great blue heron) A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Film producer. A film producer is a person who oversees film production. [1] Either employed by a production company or working independently, producers plan and coordinate various aspects of film production, such as selecting the script, coordinating writing, directing, editing, and arranging financing.

An autotroph is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) using carbon from simple substances such as carbon dioxide, [1] generally using energy from light ( photosynthesis) or inorganic chemical reactions ( chemosynthesis ). [2] They convert an abiotic source of energy (e.g. light) into ...
Photosynthesis ( / ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their activities.
