The various steps in a food chain at which the transfer of food/energy takes place are called trophic levels.In a food chain, each step representing an organism forms a trophic level.
For example,
Grass–> Grasshopper–> Frog–> Snake
In the above food chain Grasshopper eats grass, frog eats the grasshopper and snake eats the frog. Thus, Plants are the producers, and represents the first trophic level. Grasshoppers are the primary consumers, and represent the second trophic level. Frogs are the secondary consumers, and represent the third trophic level. Snakes are the tertiary consumers and represent the fourth trophic level.
Equitable distribution of resources means every stakeholder has equal access to these resources. There should be equitable distribution of resources because 1. Each stakeholder will get their share of the resources. 2. The excessive exploitation of resources would not there.

If the resources are used with long term perspective: The demand of present as well as the future generations will be met. If the resources are used in the long run, there might be enough time for the resources to get replenished. In such a situation, no generation would be deprived of resources.

Advantages of exploiting resources with short term aims: It provides the immediate advantage of meeting current basic human needs. Fast industrialization and development.

Hydrogen gas is usually liberated when an acid reacts with a metal. When zinc granules react with dilute sulphuric acid, then the bubbles of the soap solution are formed. These soap bubbles contain hydrogen gas and zinc sulphate solution is formed. The evolved hydrogen gas can be tested by taking aRead more
Hydrogen gas is usually liberated when an acid reacts with a metal.
When zinc granules react with dilute sulphuric acid, then the bubbles of the soap solution are formed. These soap bubbles contain hydrogen gas and zinc sulphate solution is formed.
The evolved hydrogen gas can be tested by taking a burning candle near soap solution containing hudrogen gas . If candle burns with pop sound, it confirms the evolution of hydrogen gas.
What are trophic levels? Give an example of a food chain and state the different trophic levels in it.

How would these advantages differ from the advantages of using a longterm perspective in managing our resources?
If the resources are used with long term perspective: The demand of present as well as the future generations will be met. If the resources are used in the long run, there might be enough time for the resources to get replenished. In such a situation, no generation would be deprived of resources.
