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.

Debora [2.8K]

Each of pollan's chapters focuses on one particular plant and pollan suggests that each plant satisfies a specific human desire. The potato satisfies our desire for control – even more so now that we control its genes.

Though people might consider potatoes ordinary everyday fare, history demonstrates how crucial this vegetable is to humankind. Prior to the invention of the potato, conditions were challenging; many people, particularly in northern European nations, suffered from starvation and famine.

Malnutrition and starvation were eradicated in the countries that embraced the potato, and as a result, they grew stronger and more powerful. It is even conceivable that the potato spread resulted in a transfer of power from southern European nations to northern ones.
