Underemployment is a great wastage of time of otherwise very capable persons. Underemployment leads to frustrations as one does not earn and get to do as one would love to and is qualified to.
The problems that arise due to underemployment are:
-Low per capita income.
-Low standards of living.
-Job frustration and stress.
-Less productivity in a nation and hence a low level of the gross domestic product.

After he flew into the storm, the narrator couldn't see anything outside the plane. His plane jumped and twisted in the air. He observed that his compass was turning round and round. It seemed to be dead. He found that the radio also stopped working. Suddenly, he saw another aeroplane which was black and it had no lights. Its pilot waved at him, asking him to follow. He followed the pilot for half an hour. Suddenly, he observed that he was using his last fuel tank and he would be able to fly hardly for five or ten minutes. Then, the other pilot started to go down and he followed. Soon, he found that he had came out of the clouds when he saw the runway.

Factorise 3825 as follows:
3825=3×3×5×5×17=32×52×17
Since, 3,5 and 17 are prime numbers as these are the numbers that are only divisible by themselves.
Hence, 3825=32×52×17

Food web is a network of food chains where all the chains are naturally interconnected.
Each organism is generally eaten by two or more kinds or organisms which are again eaten by several other organisms and so instead of straight line food chain, the series of organisms dependent on one another food can be shown by branched lines which is called as a food web.
Flow of energy in a food chain is unidirectional, once it reaches the next tropic level it does not come back again.
For example- energy which passes to the herbivores does not come back again to autotrophs.

| Biotic factors include all the living components present in an ecosystem | Abiotic factors refer to all the non-living, i.e. physical conditions and chemical factors that influence an ecosystem |
|
Examples |
|
| Examples of biotic resources include all flora and fauna | Examples of abiotic factors include sunlight, water, air, humidity, pH, temperature, salinity, precipitation, altitude, type of soil, minerals, wind, dissolved oxygen, mineral nutrients present in the soil, air and water, etc. |
|
Dependence |
|
| Biotic factors depend on abiotic factors for survival and reproduction | Abiotic factors are completely independent of biotic factors |
|
Origin |
|
| Biotic components originate from the biosphere | Abiotic components originate from the lithosphere, hydrosphere and atmosphere |

| Biodegradable waste | Non-biodegradable waste |
| Those which can be easily degraded by the decomposers into substances that go into soil and are harmless to the environment. | Those which cannot be degraded by the decomposers and thus remain in the environment causing pollution. |
| They are natural wastes. | They are synthetic wastes. |
| Examples- vegetables wastes, animal excreta | Examples- plastic, polythene |

The trophic level is the position an organism occupies in the food chain. The first trophic level known as the base of the ecosystem has the highest energy concentration which is transferred to the organisms at different trophic levels. Following are the different levels of an ecosystem:
- Producers: Plants and other autotrophs are known as producers. They prepare their own food using sunlight and carbon dioxide by the process of photosynthesis. This energy is transferred to the organisms that feed on the producers.
- Primary Consumers: This is the second trophic level which includes all the herbivores. Animals such as cows, buffaloes, deer, few insects cannot prepare their food and rely on plants and natural products for nutrition.
- Secondary Consumers: A few organisms such as rats, foxes, fish belong to the third trophic level. These are secondary consumers and derive their nutrition from the primary consumers.
- Tertiary Consumers: This is the fourth trophic level that includes all the carnivores and omnivores.
- Apex Predators: This is the final trophic level of the ecosystem. The animals belonging to this trophic level have no predators of their own. Eagles, lions, anacondas, belong to this trophic level.

Following are some points that would help in preventing this problem at a global level:
Avoid Using Pesticides: Natural methods should be implemented to get rid of pests and weeds instead of using chemicals. One can use eco-friendly chemicals to remove the pests or remove the weeds manually.
Minimize the Use of Vehicles: The vehicles emit a large amount of greenhouse gases that lead to global warming as well as ozone depletion. Therefore, the use of vehicles should be minimized as much as possible.
Use Eco-friendly Cleaning Products: Most of the cleaning products have chlorine and bromine releasing chemicals that find a way into the atmosphere and affect the ozone layer. These should be substituted with natural products to protect the environment.
Use of Nitrous Oxide should be Prohibited: The government should take actions and prohibit the use of harmful nitrous oxide that is adversely affecting the ozone layer. People should be made aware of the harmful effects of nitrous oxide and the products emitting the gas so that its use is minimized at the individual level as well.
