an organism that must eat to obtain its energy is called a/an
1 Food Chains. . 2  All living organisms (plants and animals) must eat some type of food for survival. Plants. make their own food through a process called. 3  photosynthesis. . Using the energy from the. sun, water and carbon dioxide from the atmosphere and nutrients, they chemically make. their own food. This process is called chemosynthesis . Transfer of Energy Consumers cannot make their own food. Instead they obtain energy by eating producers and other consumers. The energy stored in the molecules of one organism is transferred to another organism when one organism consumes another. Organisms get energy in different ways. Producers are organisms that get their energy directly from the sun. All plants are producers. The chlorophyll in plant cells traps the sun's energy. The plant uses the sun's energy + water + carbon dioxide to make sugar that the plant then uses for its life functions. Animals such as snails, deer, grasshoppers, rabbits and monkeys eat leaves, usually without killing the plants. Many others eat seeds, flowers and fruits. These primary consumers package the sunlight energy as a mixture of proteins and fats we call meat. Primary consumers. depend on plants and algae. process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high energy carbohydrats such as sugars and starches. Energy in the form of food is the key to staying alive. Every living thing has to have ways to get energy. Life's second great invention was to find a way to use light to make a living. Photosynthesis transforms radiant light energy into chemical energy. The produce their own food! Another group of organisms in the world** must get their energy by eating other organisms. If you aren't able to make your own food then you are not a producer, so you must be something called a consumer. Consumers are the organisms that must eat other organisms for energy. But there are different types of consumers. In biology, an organism (from Greek: οργανισμός, organismos) is any contiguous living system, such as an animal, plant, fungus, protist, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. For example, in the food chain shown below, the small fish (silverside) gets its energy by eating the plankton and the large fish (bluefish) gets its energy by. eating the small fish. Finally, the bacteria eats the fish after it dies, getting its energy from. the large fish. View Full Document. Organisms that can't make their own food and have to get their energy by consuming other organisms are called heterotrophs . Energy can be converted from one form to another and can be transferred from one organism to another. Most of the energy comes directly or indirectly from the sun.
