paragraph explaining how energy flows through energy pyramid trophinc level producer primary consumer desompsor sun secondary co
Kitty [74]

Answer:

Explanation:

Okay so, The Energy pyramid is the pyramid and order which energy is used and recycled. At the top of the pyramid you have the Animals at the top of the food chain such as humans, lions, ect. At the bottom you'll have, of course, things at the bottom of the food chain such as grass. How it works is the grass turns the sunlight into energy, which the grass is then consumed by an insect such as a grasshopper. The energy that was given to the grass is now in the insect. The insect gets consumed by one of its hundreds of predators, which is then consumed by the superiors of the food chain such as ourselves. Then of course we die then that's where the decomposers come in. Just munching on your remains and converts into the energy for mushroom. Then it starts all over again.

How the extensive regenerative power of planaria and starfish may be used as a mean of asexual reproduction
Ostrovityanka [42]
<span>Planaria have a huge regenerative power because of the presence of adult stem cells called neoblasts. If you cut Planaria into pieces, each piece can regenerate into a complete organism and that’s a form of asexual reproduction. Cells which are located on the wound site proliferate to form a blastema-mass of cell that will grow into a new organ. Those cells will differentiate into new tissues and regenerate the missing parts.</span>
<span>The similar thing is happening with starfish.</span>

Fully explain how cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken
Marianna [84]
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation. Oxidative phosphorylation is powered by the movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion.
These electrons come originally from glucose and are shuttled to the electron transport chain when they gain electrons.


As electrons move down the chain, energy is released and used to pump protons out of the matrix, forming a gradient. Protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water. Glycolysis can take place without oxygen in a process called fermentation. The other three stages of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen in order to occur. Only oxidative phosphorylation uses oxygen directly, but the other two stages can't run without oxidative phosphorylation.).
