As, the arrow provides us with a more directed way for understanding the transmission of energy through different organisms and there respective levels inside the ecological pyramid.

While, the increase in the level of scavengers or the animals which consumes the left overs of other living beings is balanced with the addition of the secondary consumers to the aquatic ecosystem.As, it will provide equal chances and energy to the different beings inside the ecosystem.

According to the food chain below, which of these organisms most likely contains the least concentration of toxins (DDT) ?

agasfer [191]

Answer:

Hawk

Explanation:

Dichlorodiphenyltrichloroethan which is also known as DDT is a colorless, tasteless and almost odorless crystalline chemical compound. It was originally developed as an insecticide and it causes harm to wildlife animals.

When the chemical are sprayed or gets in contact with the soil it is the terrestrial organisms such as plants and primary consumers who gets affected the most due to direct contact with the chemical.

Animals such as hawks who are arboreal and tertiary consumers from the list of options don’t get affected directly from the source of the DDT contamination which makes them least affected.
