What is an organism that consumes another organism?
Heterotroph (consumer) An organism that consumes another organism for food. Food chain. A series of organisms in which energy is transferred to another.
What kind of organisms obtain their energy from the dead organisms?
Decomposers are made up of the FBI (fungi, bacteria and invertebrates—worms and insects). They are all living things that get energy by eating dead animals and plants and breaking down wastes of other animals.
Which organism obtains its energy exclusively from dead or decaying matter?
Organisms that obtain their nutrition from dead and decaying organic matter are known as saprotrophs or saprophytes. These include a variety of fungi and bacteria as well as a number of other organisms that resemble fungi such as water molds.
How do other organisms obtain energy?
Organisms acquire energy by two general methods: by light or by chemical oxidation. These autotrophs provide energy for the other organisms, the heterotrophs. Heterotrophs are organisms that acquire their energy by the controlled breakdown of preexisting organic molecules, or food.
How organisms obtain their food?
Autotrophic organisms make their own food by a process called photosynthesis. Green plants, for example, manufacture sugar and starch from carbon dioxide and water using the energy of sunlight to drive the necessary chemical reactions. Heterotrophic organisms obtain their food from the bodies of other organisms.
What is an example of mutualism?
A mutualistic relationship is when two organisms of different species “work together,” each benefiting from the relationship. One example of a mutualistic relationship is that of the oxpecker (a kind of bird) and the rhinoceros or zebra. The oxpeckers get food and the beasts get pest control.
How do organisms get energy from the food they eat?
Heterotrophs obtain food by eating other organisms. Heterotrophs are also known as consumers. Organisms mainly use the molecules glucose and ATP for energy. In a process called cellular respiration, organisms’ cells break down glucose and make the ATP they need.
