Needs of Organisms are Related to the Needs of Cells They need: Energy Building materials Gases in which you breathe in Building materials energy Needs of Organisms are Related to Age and Health Children- needs equal amount of energy and building materials Teenager- need both energy and building materials but more building materials Adult- need both energy and building materials but more energy Senior Citizen- need both energy and building materials but more building materials Food/Plants are a source of energy and building materials for organisms A plant gets energy from the sun and it produces its own building materials. This process is called photosynthesis. A plant is a source of food for some animals. When the animal eats the plant, the energy and building materials are passed on. For those animals that dont eat plants carnivoresthey eat the plant eatersherbivores/omnivoresin order to get their energy. Herbivore: Burchell Zebra Herbivore/omnivore: Varanus exabthematicus Carnivore: Human, African Leopard Energy and building materials pass from one living thing to the next. Organisms get energy from the plants which get it from the sun. Organisms get building materials from just plants because plants can produce their own building materials. 100% 95% 80% 60% 42% Scavengers Carnivores/ omnivores Herbivores/ omnivores Producers West African grass leaf phytoliths acacia tree Maasai giraffe Guinea baboonBurchell ZebraAfrican ElephantAfrican termites African antelope Hecki, west African cheetahAfrican lion African leopard Crocuta hyena African white-backed vultures human
