Question

what are autotrophs ? Give one example of autotrophs.

Answer 1

Answer:

An autotroph is defined as an organism that can produce its own food using light, water, carbon dioxide, or other chemicals.

Example: Green algae, blue-green algae

Explanation:

An autotroph is an organism that produce its very own food by using light, water, carbon dioxide or different chemical substances. Because autotrophs produce their very own food, they're once in a while known as producers.

Example: Algae, Green plants

Plants are the maximum acquainted form of autotroph, however there are numerous one of a kind types of autotrophic organisms. Algae, which stay in water and whose large paperwork are called seaweed, is autotrophic. Phytoplankton, tiny organisms that stay inside the ocean, are autotrophs. Some forms of micro organism are autotrophs.

Most autotrophs use a procedure known as photosynthesis to make their meals. In photosynthesis, autotrophs use electricity from the solar to transform water from the soil and carbon dioxide from the air right into a nutrient known as glucose. Glucose is a form of sugar. The glucose offers flowers electricity.

All flowers with inexperienced leaves, from the tiniest mosses to towering fir trees, synthesize, or create, their very own meals via photosynthesis. Algae, phytoplankton, and a few micro organism additionally carry out photosynthesis.

Some uncommon autotrophs produce meals via a procedure known as chemosynthesis, in place of via photosynthesis. Autotrophs that carry out chemosynthesis do now no longer use electricity from the solar to supply meals. Instead, they make meals the use of electricity from chemical reactions, regularly combining hydrogen sulfide or methane with oxygen.

Organisms that use chemosynthesis stay in excessive environments, wherein the poisonous chemical substances wanted for oxidation are located. For example, micro organism dwelling in energetic volcanoes oxidize sulfur to supply their very own meals.

Bacteria that stay inside the deep ocean, close to hydrothermal vents, additionally produce meals via chemosynthesis. A hydrothermal vent is a slim crack inside the seafloor. Seawater seeps down via the crack into warm, in part melted rock below. The boiling-warm water then circulates lower back up into the sea, loaded with minerals from the recent rock. These minerals encompass hydrogen sulfide, which the micro organism use in chemosynthesis.

Autotrophic micro-organism that produce meals via chemosynthesis have additionally been located at locations at the seafloor known as bloodless seeps. At bloodless seeps, hydrogen sulfide and methane seep up from underneath the seafloor and blend with the sea water and dissolved carbon dioxide. The autotrophic micro organism oxidize those chemical substances to supply electricity.
