Answer : The correct answer is -
D.Protista and Eubacteria.
Autotrophs are the organisms that can synthesise their own food using substances available in their surroundings with the help of either chemical energy (chemosynthesis) or light energy (photosynthesis).
Heterotrophs on the other hand, can not synthesise their own food and depend on either plants or animals.
Out of the given options, Protista and Eubacteria conatin autotrophs or heterotrophs.
Example- Protozoa (animal-like protists) are heterotrophs that ingest or absorb their food and helps.
Algae, which is a protist and obtains nutrition through photosythesis.
Slime moulds, which are fungus-like protists and are heterotrophic.
Cyanobacteria (also called blue green alage) is a photosynthetic bacteria (belongs to Eubacteria).
B., a convergent plate boundary.
Answer:
Negative feedback results in the inhibition of an enzyme in a biochemical pathway, reducing the activity of earlier enzymes, and stopping the pathway. Positive feedback results in the activation of more enzymes, thus increasing its production of the product.
Answer:
True
Explanation:
Primary Producers: Primary producers in a coral reef ecosystem include plankton, sea weeds and sea grasses. All of these organisms are photosynthetic organisms that get their energy from the sun.
Answer:
by breaking down food molecules and transferring their chemical energy to ATP
Explanation:
All living organisms require energy in order to perform their cellular functions. These energy is in form of ATP (Adenosine triphosphate), which is the usable form of energy by cells. Organisms are able to obtain this energy via a process called CELLULAR RESPIRATION.
Cellular respiration involves the breaking down of glucose molecule (derived from the food intake) in a series of metabolic reactions to yield ATP (energy). In other words, organisms breakdown food molecules and transfer the chemical energy stored in their bonds into ATP.
