Answer:

1 positively charged sodium ion

2 sodium ion that has lost an electron

Explanation:

Sodium is represented by the symbol Na. It has an atomic number of 11. In neutral state, it has 11 protons and 11 electrons. The electron shells are filled in the order 2,8,1. Thus, one electron remains in the outermost shell. To achieve stable state, Na loses one electron. The result is the formation of sodium ion which has one positive charge and which denotes the loss of one electron.

Kryger [21]

Answer:

The food chain showing seven organisms can be drawn as follows:

Plants → grasshoppers → mice → frog → snakes→ eagles → decomposers

The plants are the primary source of food in a food chain or a food web. The animals which feed on plants will be termed as herbivores or primary consumers like the grasshopper. The organisms feeding on primary consumers will be the secondary consumers like mice.

An energy pyramid for three of the organisms can be shown as follows:

              mice (10 kilocalories)

                   ↑

        Grasshoppers (100 kilocalories)

                   ↑

       Plants ( 1000 kilocalories)

As the energy pyramid shows, only about 10% of the energy travels from one trophic level to another.
