What else can I help you with?
Compare and contrast photosynthesis and chemosynthesis?
Chemosynthesis gets its energy from oxidation of inorganic substance, photosynthesis gets its energy from light. Chemosynthesis could occur just about anywhere there are enough suitable chemicals to oxidize [metabolize], while photosynthesis could occur only when there is sufficient light.
How does chemoautotrophs obtain energy?
Chemoautotrophs (or chemotrophic autotroph), in addition to deriving energy from chemical reactions, synthesize all necessary organic compounds from carbon dioxide. Chemoautotrophs generally only use inorganic energy sources. Most are bacteria or archaea that live in hostile environments such as deep sea vents and are the primary producers in such ecosystems. Evolutionary scientists believe that the first organisms to inhabit Earth were chemoautotrophs that produced oxygen as a by-product and later evolved into both aerobic, animal-like organisms and photosynthetic, plant-like organisms. Chemoautotrophs generally fall into several groups: methanogens, halophiles, sulfur reducers, nitrifiers, anammoxbacteria and thermoacidophiles.
Is photosynthesis the only process that can make food?
No, photosynthesis is not the only process that can make food. Heterotrophic organisms, such as animals, fungi, and some bacteria, obtain food by consuming other organisms or organic matter. This process is known as heterotrophic nutrition.
What Occurs only in the presence of chlorophyll and light?
Photosynthesis occurs only in the presence of chlorophyll and light. This process allows plants to convert light energy into chemical energy in the form of glucose, which is used for growth and development. Chlorophyll, along with other pigments, capture light energy and drive the chemical reactions of photosynthesis.
What movement of the substances through a cell membrane against a concentration gradient requires energy?
no because it is a form of passive transport. only active transport requires energy. facilitated diffusion just means that it cant be just absorbed through the membrane, it must go through specific chanels or be helped by transport proteins. but because facilitated diffusion moves from higher to lower concentrations, it requires no energy.
How does non conventional sources of energy differ from conventional energy sources?
Only by being unusual or used in an unusual way.
Why CO2 is inorganic?
CO2 is considered inorganic because it does not contain carbon-hydrogen bonds, which are characteristic of organic compounds. Inorganic compounds typically do not contain carbon-hydrogen bonds and are derived from minerals or non-living sources.
What is the only type of cell transport that requires energy?
wwwwwwww
What you mean by organic and inorganic pigments?
Inorganic pigments contain only inorganic ingredients.
Does passive transport requires large amounts of energy?
No. only active transport does
How does renewable energy save money?
Energy is not renewable. The sources to make that energy may be. After the initial cost of plant and equipment some sources are practically free so the only costs are maintenance costs..
Species that takes in only inorganic nutrients is called an?
A species that takes in only inorganic nutrients is called a/an
Compare and contrast photosynthesis and chemosynthesis?
Chemosynthesis gets its energy from oxidation of inorganic substance, photosynthesis gets its energy from light. Chemosynthesis could occur just about anywhere there are enough suitable chemicals to oxidize [metabolize], while photosynthesis could occur only when there is sufficient light.
How do plants and animals get carbohydrates to use for energy?
Only as an energy source, it requires amino acids for animals to make proteins.
What is photophosphylation?
Photophosphylation is when ADP forms ATP by only using the energy from the sunlight. There are only two sources of energy that can be used and they are the sunlight and reduction oxidation reactions.
The transfer of energy through a vacuum can only be accomplished by what?
Radiation.Conduction requires contact and convection requires a motive fluid. Radiation only needs a straight line of sight with no intervening medium.
A species that takes in only inorganic nutrients called?
Autotrophs take in only inorganic nutrients. They are organisms that are capable of self-nourishment.
