Autotrophic or Heterotrophic refers to the organismal method of?
|
Obtaining nutrients
|
|
|
An organism that captures its own energy through photosynthesis, which exploits the radiant energy of the sun:
|
Autotrophs
|
|
|
An organism that captures its own energy by breaking chemical bonds:
|
Chemoautotrophs
|
|
|
Do Heterotrophs possess a digestive system?
|
They may or may not.
|
|
|
An organism that obtains it's nutrients from plants only
|
Herbivores - A type of Heterotroph with a digestive system.
|
|
|
An organism that obtains it's nutrients from animals only
|
Carnivores - A type of Heterotroph with a digestive system.
|
|
|
An organism that obtains it's nutrients from plants and animals too
|
Omnivores - A type of Heterotroph with a digestive system.
|
|
|
List the Heterotrophs which lack a digestive system
|
They are a Heterotrophic Microorganism:
1) Parasite 2) Saprophytes |
|
|
List the Heterotrophs with a digestive system
|
1) Herbivore
2) Carnivore 3) Omnivore |
|
|
An organism that obtains it's nutrients directly from the body of a living organism, simultaneously degrading the organism
|
Parasite
|
|
|
Do Parasites lack a digestive system?
|
Some have digestive systems and some don't. It's confusing in the book so just know that they are classified as the type of Heterotroph that does not have a digestive system/doesn't use their own/whatever.
|
|
|
An organism that absorbs nutrients from the remains of dead organisms
|
Saprophytes
|
|
|
Aside from Parasitic and Saprophytic, are there any other organisms without a digestive system?
|
Yes there are other, but they derive their nutrition from living organisms WITHOUT harming them. ("Commensalism" type of relationship)
|
|
|
Which heterotroph is extremely beneficial to the release and recycling of substances, promoting their availability to other organisms who depend on them?
|
Saprophytes
|
|
|
Which Heterotroph is responsible for the generation of Carbon, Nitrogen, and other mineral components and a variety of organic compounds?
|
Saprophytes
|
|
|
If an organism cannot synthesize it's own nutrients, it is termed:
|
Heterotroph
|
|
|
What is the distinguishing factor for the types of Heterotrophs that exist?
|
Lacking or having a digestive system.
|
|
|
An organism that produces complex organic compounds from simple inorganic molecules using energy from light (by photosynthesis) or inorganic chemical reactions.
|
Autotrophs
|
|
|
What kind of organism in addition to deriving energy from chemical reactions, synthesizes all necessary organic compounds from carbon dioxide?
|
Chemoautotrophs
|
