According to Ritzer, the main contribution of the notion of "global value chains" is: ? that it emphasizes the role played by multinational corporations in global production and consumption. ? that it describes how value is added to raw materials through the production process. ? that it differentiates between buyers and producers in international production networks. ? that it describes how value is generated through the production, consumption, and final disposal of goods.

00:01 Hello student, here the question is given and the question is about the relationship between traffic label.

00:07 So here we have to notice the relationships between different traffic label in case of food chain as well as food web.

00:23 So if we notice the relationship between these different traffic label, we can say as we from bottom to the top of traffic label.

00:45 So in that case, the number of participant decreases as the amount of energy as the amount of energy present in each traffic label is also decreasing.

01:18 Also decreasing because we know the only 10 % of energy can transfer to the next level of the traffic.

01:27 So these kind of way structure we can see in the energy pyramid.

01:32 So always the top one going to be very less energy.

01:38 So as we go from bottom to the top of the traffic label, this is going to be number of participant as well as this energy is also going to be decreases.

01:50 And the next question is about the factor which are going to be disrupt the psychological balance.

01:57 So the disturbance if we are talking about, so this disturbance mainly lead to the reduction of particular species in various traffic label.

02:20 So in that case, what is going to be the ecosystem impact? so here we can say this ultimately reduction or extinction of certain species, reduction or extinction of certain species from a given ecosystem.

02:49 And it may result also the explosive growth of certain type of, on the other hand, it results in explosive growth of some species which are going to be harmed the ecosystem because there need to be a balance.

03:13 So overpopulation of human is also going to be destroying the nature.

03:17 And another one is going to be also changing in the diet of the consumer.

03:22 So it ultimately going to changing the diet of consumer which now have relies on the particular type of a species and it going to decrease the population.

03:40 So ultimately, unavailability of food is going to result into the decrease in the particular population.

03:48 And the competition is between the consumer will also going to be increase.

03:54 So here the competition is also increase because where they have to invest more energy to find their food as well as the reproduction and a growth purposes.

04:05 So there is a need of extinction of this type of consumer and the energy flow also going to be decreases because there will be a less or no participants in a particular traffic level.

04:26 So what are the going to affect on each traffic level? so if we are talking about the primary producer first, so we know there will be a primary producers are the mainly the plants or the green vegetation...
