The 13 elements that are room temperature gases are radon (Rn), xenon (Xe), krypton (Kr), argon (Ar), chlorine (Cl), neon (Ne), fluorine (F), oxygen (O), nitrogen (N), helium (He) and hydrogen (H). Most non-metals in the periodic table have a gaseous elemental form.
Answer:
Si.
Explicación:
Sí, un gas se puede condensar cuando su temperatura disminuye porque cuando la temperatura del área circundante del gas disminuye, se produce una condensación que cambia el estado de la materia i. mi. de gas a estado líquido. La principal razón de esta condensación es la aproximación de moléculas de gas que están muy alejadas unas de otras. Con una temperatura más baja, el volumen disminuye y las moléculas de gas se combinan para formar un líquido.
I wonder what sort of stuff happens up there that nobody is aware of. All the different kinds of possibilities. And if there is life, then what would they be doing and how are their ways of life?
Complete question:
A food web is a diagram that shows the interaction of organisms in an ecosystem. Which statement best describes the transfer of energy in a food web?
- The amount of energy transferred at each trophic level decreases because some is lost as heat.
- The amount of energy transferred at each trophic level is the same because energy is conserved in a system.
- The amount of energy transferred at each trophic level increases because the size of the organisms increases.
- The amount of energy transferred at each trophic level is different in land and marine ecosystems because the animals are different.
Answer:
The correct answer is
- The amount of energy transferred at each trophic level decreases because some is lost as heat.
Explanation:
The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. The next links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
From the whole quantity of energy that reaches the earth's surface, only 0.1 or 1% is absorbed by autotroph organisms or producers.
From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.
At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.
The progressive reduction of energy determines the number of trophic levels (4 or 5). There are rarely more than four links, or five levels, in a trophic network. Over time, all the energy that flows through the trophic levels is lost as heat.
