Why is the number of trophic level restricted to four or five in a food chain?

Biology

All organisms need energy to survive. It requires many units of lower trophic level organisms to feed the next trophic level. For example many first order consumers (fish) are required to feed one crocodile (top order consumer). This is because energy is lost as heat at each trophic level, so the energy available to the top feeding level is far lower than that of the producers (plants). This is what restricts the number of trophic levels in a food chain to four or five.

Electricity is added to recharge a battery. What is added to ADP to form ATP?
White raven [17]

Electricity is added to recharge a battery. A third phosphate group  is added to ADP to form ATP.

ATP or Adenosine triphosphate contains adenine, ribose and 3 phosphate groups.

ADP is converted to ATP by the following reaction:

ADP+Pi+energy⇄ATP

The analogy between battery and ATP can be explained as ATP is higher energy form and ADP is lower energy form like charged and uncharged form of the battery. When the terminal or third phosphate is removed from the ATP it becomes ADP and releases energy like a battery. The additional phosphate group when added to ADP forms the ATP molecule like the energy spent by the batteries are recharged by putting in additional energy. Here the additional energy is provided by the third phosphate group.

agasfer [191]

Answer:

Microtubules composed of tubulin protein.

Explanation:

The cytoskeleton is composed of three well defined filamentous structures: microtubules, microfilaments, and intermediate filaments. Each of these filamentous structures is a polymer of proteinic subunits united by weak, not covalent connections.

Microtubules are long hollo cylindric tubes with no ramifications of a diametre near to 25 nanometers. They are constituted by two subunits of tubulin protein which polymerize to form microtubules. These filaments shape the cell and are involved in intracellular transport.  Microtubules extend from an organizing center near the nucleus to the cellular surface.
