During the slaughter process, germs on an animal's hide that came from the intestines can get into the final meat product. The plants in the African Savanna are specialized to survive in long periods of drought and heat that occur in the dry months. [6]:370, Food chains are often used in ecological modeling (such as a three-species food chain). Some producers, like plants, get the energy they need to make food from the sun. A certain amount of energy is converted into biomass, when it gets transferred between two successive trophic levels. In the 10th century, a scientist and philosopher named Al-Jahiz came up with the idea of the food chain. It will . For example, a food chain might start with a green plant as the producer, which is eaten by a snail, the primary consumer.
