DDT is an insecticide that was formerly used to control insects that would eat crops. It was banned from use in the 1970s.
Reil [10]
<h2>It contains toxins</h2><h2>It killed off bird populations.</h2><h2>It caused harm to human populations.</h2>

Explanation:

Let us understand the term DDT

DDT : Dichlorodiphenyltrichloroethane

  • This is a crystalline chemical compound
  • Basically used for protecting insects eating crops
  • It is colorless, odorless, tasteless
  • Initially used as pesticides

It killed off bird populations: Though it does not kill birds directly by consuming, it has indirectly damaged the egg by making the egg's shell too thin which gets broken easily.

It controlled diseases like malaria: Since this option talks about positive attribute of DDT, this option stands invalid. This chemical compound controls mosquitoes attacking the crop.

It caused harm to human populations: DDT causes vomiting, tremors or shakiness, and seizures

It contained toxins: It contains moderate toxins.

Use the model here to describe the transfer of matter and flow of energy from one trophic level to another within an ecosystem.
Andrews [41]

The food chain and food web are used to transfer energy. Plants, who are the primary energy providers in the ecosystem, use their chloroplasts to collect sunlight, which is then partially converted into chemical energy during photosynthesis.

a)

  • When herbivores eat (are the primary consumers of) plants as food, this energy is transferred to the primary consumers in the food chain.
  • This energy is stored in various organic products in plants. Then, the chemical energy contained in plant products is converted into kinetic energy, degrading the energy by turning it into heat. The secondary consumers come next.
  • Further deterioration will occur when these herbivores are consumed by secondary consumers.
  • Finally, energy will once more be destroyed when tertiary consumers eat the carnivores. As a result, the energy flow is only in one direction i.e., unidirectional.

b)

  • Additionally, the energy flow in a food chain adheres to the 10% law.
  • This law states that only 10% of energy is transferred from one trophic level to the next, with the remaining 90% being lost during the digestion process of the organism itself.

c)

  • There are typically fewer organisms at the top of an energy pyramid because It has the least quantity of energy, the top level of an energy pyramid has the fewest organisms.
  • Most ecosystems only have four trophic levels because there is eventually insufficient energy to maintain further trophic levels.

d)

  • For instance, let us assume that a plant at the producer level produces 1000 Kcal of energy.
  • When a primary producer eats this plant, it will only get 10% of the energy produced by the plant i.e., 1000/10 = 100 Kcal. the rest 90% will be used up by the plant itself for its metabolism.
  • Further when a secondary consumer eats the primary consumer, it will only get 10% of the energy produced by the plant i.e., 100/10 = 10 Kcal.
  • Lastly, as the tertiary consumer eats the secondary consumer, it will only get 10/10 = 1kcal.
