2 Food Chains Food Chain What do food chains show? What do the arrows represent?A series of events in which one organism eats another and obtains energy.Food chains show the transfer of energy in an ecosystemThe arrows represent the transfer of energy.
3 All Food Chains start with the sun After the sun is an organism that can do photosynthesis. Like plants and phytoplankton.Sunlight + Carbon Dioxide + Water = Energy This process is called PhotosynthesisWhat do food chains start with?What type of organism is after the sun?Describe photosynthesis.
7 ProducersAn organism that can make its own food . They use carbon dioxide, water and sunlight to make energy, through a process called photosynthesis. Producers are the source of all food in an ecosystem. Without producers there is no food chain.FlowersPhytoplanktonTree
8 Two major groups of decomposers are: Bacteria Fungi. Organisms that break down wastes and dead organisms and return the raw materials to the environment.Two major groups of decomposers are:BacteriaFungi.
9 Consumers3 types of ConsumersAn organism that obtains energy by feeding on other organisms.Ex: Deer, Humans, Snakes, Bat, Cat, Hippopotamus, Cricket, RabbitHerbivores, Omnivores and CarnivoresFood Chain Game
18 Energy PyramidAn Energy Pyramid shows the amount of energy that moves from one feeding level to another in a food web. The most energy is at the producer level. At each level there is less available energy.
19 Biomass. The measure of the total. dry mass of organisms in a Biomass The measure of the total dry mass of organisms in a given area. Producer(bottom level) always the biggest level, always have the largest biomass.
