Nature and life When the wind blows, the barrel maker profits. Japanese proverb: Kaze-ga-fukeba, oke-ya-ga-moukaru.（⾵が吹けば桶屋が儲かる） 6. The web of nature 1 2 Web of nature 1. Function of photosynthetic organisms 2. Carbon cycle 3. Nitrogen cycle Organisms (including humans) rely on ecosystem. 3 4 A solar-powered web Varieties of ecosystem Global scale Local scale (sloth’s back) Ecosystem = Living things + Non-living things Pauli et al. 2014 5 6 Ecosystem relies on photosynthesis Food chain Carnivorous animals Photosynthesis (Consumer) ・Plants produce oxygens from CO2 and H2O by photosynthesis. Carnivorous animals (Consumer) ・Carbon is used as glucose for growth of plant‘s body. Carnivorous animals (or omnivorous) (Consumer) Plant body: Cellulose (C6H10O5)n Plants can store carbon into the body through the photosynthesis. Photosynthetic plants Herbivorous animals (or omnivorous) (Producer) (Consumer) 7 8 Food web Decomposers How organisms return to inorganic compounds.
