Toiduallikas refers to a source of food. This term can encompass a wide range of origins from which organisms obtain sustenance. In a biological context, it can describe the trophic level an organism occupies within an ecosystem, such as a producer, primary consumer, or secondary consumer. For example, plants are a food source for herbivores, which in turn are a food source for carnivores.

Humanity relies on diverse food sources, including agriculture, livestock, fisheries, and wild harvesting. Agricultural food sources involve cultivated plants like grains, fruits, and vegetables, as well as domesticated animals raised for meat, dairy, or eggs. Fisheries provide food from aquatic environments, encompassing fish, shellfish, and other marine life. Wild harvesting includes foraging for wild plants and hunting wild animals.

The concept of food sources is also relevant in discussions about food security, sustainability, and public health. Understanding where our food comes from is crucial for ensuring adequate supply, minimizing environmental impact, and promoting healthy diets. Changes in food sources, such as shifts from local to global supply chains or the adoption of new food technologies, can have significant implications for societies and the environment. The term can also be used in a more general sense to refer to any item or substance consumed for nourishment.
