<span>The energy (from food) an organism consumes is mostly burned for the purposes of movement and keeping warm. In terms of the trophic levels, this is energy "wasted" (heat radiated by an animal out to the surrounding environment) and not passed on to the next level as consumable food. For instance, imagine that the sun's rays (the ultimate source of energy in the "food chain") striking a portion of the ocean on the Earth's surface is equal to one million energy units. Much of that energy is absorbed by the ocean's water molecules, but the amount left over is intercepted by phytoplankton and turned into food by photosynthesis. At this first trophic level, the amount of energy the phytoplankton store as food is 20,000 units. At the next trophic level, the zooplankton consume the phytoplankton, but just 2,000 units of energy is passed on as food in the bodies of the tiny animals. Small fish (at the next trophic level) scoop up the little zooplankton, but their bodies only represent 10% of the previous level's energy units - therefore, the amount of energy left is now 200 units. By the time large fish at their trophic level eat the smaller fish, 20 energy units remain. Finally, at the point where humans (at the final trophic level) catch these fish, only 1 or 2 energy units are left. As this example shows, the approximate efficiency at which energy is transferred through the "food chain" from one level to the next highlights the great amount of energy lost in an ecosystem, and how a relatively small amount of energy is actually available to an organism in the form of food that it needs to survive and perpetuate.</span>
Answer:
D. The granularity of locks.
Explanation:
X-locks is one of the locks used in locking database in what is known as adaptive server. Other types of locks for locking database are the S-lock, IS-locks, and the IX- locks. The locks are used mainly for control purpose[ that is when a data is been used by a lot of people, the locks make sure that there is consistency in the data.
The option D is correct that is; ''The moment that X-locks are released will determine the granularity of the locks'' The granularity of the locks simply means the amount in which the data can be locked at the same time.
Answer:
. The authorities have closed the casino.(change in passive)
Answer: No the tools are not physically connected to technology to the point they would be rendered unusable like a wrench in a computer or gear box
Explanation:
energy source
Explanation:
After wire and filament have been connected, for the conduction of electricity, an energy source is required.
In the energy source, electrical energy is produced.
- The energy source can be a simple electrochemical cell.
- It can be a generator.
- It can also be current from the national grid.
- The energy source produces current which is carried in wire and it powers the filament
