Food is usually of plant, animal, or [[Fungus|fungal]] origin and contains essential nutrients such as [[carbohydrate]]s, [[fat]]s, [[protein (nutrient)|proteins]], [[vitamin]]s, or [[Mineral (nutrient)|minerals]]. The substance is [[Ingestion|ingested]] by an organism and assimilated by the organism's [[Cell (biology)|cells]] to provide energy, maintain life, or stimulate growth. Different species of animals have different [[List of feeding behaviours|feeding behaviours]] that satisfy the needs of their [[metabolism]]s and have evolved to fill a specific [[ecological niche]] within specific geographical contexts. [9] => [10] => [[Omnivore|Omnivorous]] humans are highly adaptable and have adapted to obtain food in many different ecosystems. Humans generally use [[cooking]] to prepare food for consumption. The majority of the [[food energy]] required is supplied by the industrial [[food industry]], which produces food through [[Intensive farming|intensive agriculture]] and distributes it through complex [[food processing]] and [[food distribution]] systems. This system of conventional agriculture relies heavily on [[fossil fuel]]s, which means that the food and agricultural systems are one of the [[Greenhouse gas emissions from agriculture|major contributors to climate change]], accounting for as much as 37% of total [[Greenhouse-gas emissions|greenhouse gas emissions]].{{Cite book |url=https://www.sapea.info/wp-content/uploads/sustainable-food-system-report.pdf |title=A sustainable food system for the European Union |publisher=Science Advice for Policy by European Academies |year=2020 |isbn=978-3-9820301-7-3 |location=Berlin |page=39 |doi=10.26356/sustainablefood |access-date=14 April 2020 |archive-url=https://web.archive.org/web/20200418105107/https://www.sapea.info/wp-content/uploads/sustainable-food-system-report.pdf |archive-date=18 April 2020 |doi-access=free|author1=SAPEA }} [11] => [12] => The food system has significant impacts on a wide range of other social and political issues, including [[sustainability]], [[biological diversity]], [[nutritional economics|economics]], [[population growth]], [[water supply]], and [[food security]].
