Take a look at 2 organisms in the open ocean. What zone do they live in, then make a food chain with the 2 organisms. Label the organisms and use arrows to state which way the food chains go.

Is there a picture attached?

Explanation:

Wire A has twice the resistance of wire B.

Wire A and wire B have the same resistivity.

Explanation:

- Resistivity is a property of a material, that tells how much is the material able to oppose to the flow of current through it. The value of the resistivity of a wire depends on the material only: this means that two wires made of the same material have same resistivity. Since both wire A and B here are made of copper, they have the same resistivity.

- Resistance of a wire instead is given by

where

is the resistivity of the material

L is the length of the wire

A is the cross-sectional area of the wire

Here, the two wires have same resistivity and same cross-sectional area, while wire A is twice as long as wire B (so, L for A is twice the value of L for B): therefore, the resistance of wire A will be twice that of wire B.
