Answer: The energy decreases every time an organism consumes one another. the primary producers have the most energy, then it goes to the primary consumers, then the secondary and then finally the tertiary consumers which are the ones that get the lest amount of energy.
Explanation: Hope this helps.
They are the same easily answer metals all the way
Answer:
structure of argon
Explanation:
The nucleus contains 18 protons ( red) and 22 neutrons (orange). 18 electrons (white) occupy shells ring.
Answer:

Explanation:
The products of this reaction are given by:

Firstly, dichromate anion becomes chromium(III) cation, let's write this change:

The following steps should be taken:
- balance the main element, chromium: multiply the right side by 2 to get 2 chromium species on both side:

- balance oxygen atoms by adding 7 water molecules on the right:

- balance the hydrogen atoms by adding 14 protons on the left:

- balance the charge (the total net charge on the left is 12+, on the right we have 6+, so 6 electrons are needed on the left):

Similarly, tin(II) cation becomes tin(IV) cation:

Now that we have the two half-equations, multiply the second one by 3, so that it also has 6 electrons that will be cancelled out upon addition of the two half-equations:


Add them together:

Adding the ions spectators:

D-1 electron in their outer energy level.
