Why do food chains not exceed 4 links?
because the way a food chain works is energy is transferred between trophic levels, but as you move up each trophic level, about half of the energy is lost, which means when you get to the fourth trophic level, only about 10% of the original energy is remaining, so adding another level would mean that the creature would have to consume 10 times as much of its respective prey to get the energy equivalent of 1 of the creatures at the first trophic level. so in other works, energy consumption would be too inefficient
What happens to air pressure when you move upward away from sea level?
The farther up away you are from sea level the less air pressure there is.
What happens to organisms as we move through the biological hierarchy from the kingdom to species level?
The number of organisms becomes smaller as you move to more specific.
What happens to atoms size as you move down the periodic table in the noble gases?
As you move down the periodic table in the noble gases, the atomic size generally increases. This is because the number of energy levels, or electron shells, increases down the group. With each additional energy level, the atomic radius expands, resulting in larger atoms.
What are three reasons why energy transfer between trophic levels is not 100 percent?
Energy transfer is inefficient because energy is lost while moving from one trophic level to another. This is because * Not the entire organism is consumed or digested. Parts such as rootr, woody stems, bones, scales, feathers etc aren't eaten, and some materials that are such as cellulose cannot be digested. * Energy is used up by organisms in each trophic level for movement and transport inside their bodies. * Energy is used in respiration and is released from the body of the organism as heat. * Energy becomes lost in excretion.
What is called when each step in a food chain or web?
the steps are known as trophic levels as move down the levels energy from the organisms tends to be lost to the environment
What happens to the energy levels are you move from left to right on the periodic table?
The energy level generally remains the same in a period (as we move from left to right). Down a period, the energy level increases.
For what purpose do organisms use most of the energy available to a consumer trophic level?
For growth and energy to live, move, and repair themselves.
Define the 10 percent law that describes energy transfer between organisms?
The 10 percent law states that only approximately 10 percent of energy consumed at one trophic level is transferred to the next trophic level. The remaining energy is lost as heat or utilized for metabolic processes. This law helps explain why food chains are generally limited in length, as energy becomes increasingly scarce as you move up the trophic levels.
What happens to the biomass of the organism as trophic levels increase?
Energy and biomass decrease as the trophic levels increase.The general rule is that only about 10% of the total energy consumed from the previous trophic level will be passed onto the next level as useable energy. As a result it takes a large biomass of producers (plants) to support the total biomass of primary consumers. The primary consumers use the energy they obtain from the plants to maintain body temperature and move or it is lost as waste. Most energy is considered to be lost as heat. This pattern is repeated for secondary consumers and so on. (This is a generality; the amount of energy transferred changes in real situations.)All life is directly related to the original energy source, in most cases the sun. The higher up you go in the trophic level, the less life (overall biomass) that can be supported by the original energy source due to the loss of energy in each level.

What happens to elements as you move down the periodic table?
they do something
What happens to the density of the layers of the earth as you move further down?
They get thicker as you go down.
Does an excited electron move up or down an energy level?
The excited electron move up.
What are four main elements in food that help energy to move from one trophic level to another?
producer s, primary consumers, secondary consumers, and Decomposers!
What happens to the energy level as you move up the energy pyramid?
10% of energy is lost as you move from 1 level to the next. So at the end 90% if the energy will be lost as heat.
How to pass level 2 on briker?
First you move right three times then move down twice then you move left once then move up once then move right twice then move down once then move left three times down twice and lastly right once.
