This question is more for Biology than Chemistry, but the role of producers is to make energy (food) to be consumed. In a pyramid diagram, the producers would be at the bottom. Now going up the pyramid, the primary conumers are the first to consume producers and obtain energy from them. As you go up the pyramid, the secondary consumers will consume the primary consumers as a way to obtain energy, and the same goes for tertiary consumers towards secondaries.
As you go up the energy pyramid, you will notice a trend that there is less energy being obtained from each consumer. In other words, the producers will ALWAYS have more energy than the tertiary consumers.
I hope this answers your question.
Metals tend to become cations becauase they lose electrons
Answer:
A decrease in temperature would decrease kinetic energy, therefore decreasing collisions possible.
Explanation:
A gas at a fixed volume is going to have collisions automatically. If you decrease the temperature (same thing as decreasing kinetic energy) you are cooling down the molecules in the container which gives them less energy and "relaxes" them. This decrease in energy causes them to move around much slower and causing less collisions, at a much slower rate. In a perfect world, these collisions do not slow down the molecule but we know that they do, just a very very small unmeasurable amount.
the nebular theory states that the solar systems developing <u><em>rotations </em></u>revolve around sun. it is located in the milky-way. revolving around the <u><em>sun</em></u>, with <u><em>gravity</em></u> pulling it, an interstellar cloud of dust and gas, is formed. (i.e. the nebula that we are speaking)
this formation is a<u><em> protostar</em></u>. the idea in the theory states that the <u><em>nebula</em></u> has flattened into a <u><em>disk</em></u> called the "protoplanetary disk"; and over time, the debreis eventually formed this disk. (i.e. creating the milky-way)
hopefully this helped, thank you!! :D
most metals conduct electricity and are very dull to the look. most metals are toxic if eaten and are hard.
aluminum is a type of metal they is softer than the opther and conducts eletricty like a boss.
nickel on the opther hand is also a metal but does not conduct a lot of electricy.
metals can be bent and others can break,
