1. fossil fuels should be used judiciously as they can be exhausted if used excessively and will take time to replenish
2. fossil fuels are fuel formed by natural processes such as decomposition of dead organisms .
3. They can be easily exhausted
4.The calorific value of a fuel is the quantity of heat produced by its combustion i.e at constant pressure and under “normal” (standard) conditions (i.e. to 0 degree C and under a pressure of 1,013 mbar).
5. COMPRESSED NATURAL GAS . CNG preferred than fossil fuel because it produce greenhouse gases upon combustion, it is a more environmentally clean alternative to other fossil fuels
The answer is option B. False. The amount of energy that a food contains can be measured not by vitamins but by calories. Vitamins are organic compounds which are found in foods, and their role in the body is to sustain and improve growth and development.
Overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change soil erosion, poor air quality and undrinkable water.
Mutualism: <span>The bee and the flower. Bees fly from flower to flower gathering nectar, which they make into food, benefiting the bees. When they land in a flower, the bees get some pollen on their bodies, and when they land in the next flower, some of the pollen from the first one rubs off, pollinating the plant. This benefits the plants.
</span>Parasitism: Fleas and dogs. <span>Fleas harm their hosts, such as dogs, by biting their skin, sucking their blood, and causing them to itch.
</span>Commensalism: The relationship between cattle egrets and cattle.<span>The cattle egret will eat insects that have been disturbed when the cattle forage. One species benefits while the other neither benefits or are harmed.
</span>Predation: The relationship between lions and zebras. The predator, the lion, kills and feeds on the prey, the zebra.
Competition: <span>One example of competition between two organisms would be chipmunks and squirrels. They compete for nuts to be able to feed themselves and survive.</span>
The reason desalination isn’t used more is because the energy requirements are so high that it cost a lot of countries too much money
