Industrialization increases the demand for energy. Fossil fuels are easily accessible sources of energy that fulfil this demand. The increased use of fossil fuels has a harsh effect on the environment. Too much exploitation of fossil fuels increases the level of greenhouse gas content in the atmosphere, resulting in global warming and a rise in the sea level. It is not possible to completely reduce the consumption of fossil fuels. However, some measures can be taken such as using electrical appliances wisely and not wasting electricity. Unnecessary usage of water should be avoided. Public transport system with mass transit must be adopted on a large scale. These small steps may help in reducing the consumption of natural resources and conserving them.

2. If carnivores are killed, then the population of herbivores would increase to unsustainable level.
3. If producers are killed, then the nutrient cycle in that area would not be completed.

Yes, the impact of removing all the organisms in a trophic level will be different
for different trophic levels. For example, on removing producers; herbivores would not
be able to survive or they would migrate and ecosystem would collapse. If herbivores are
removed, producers would grow unchecked and carnivores would not get food. If
carnivores are removed, herbivores would increase to unsustainable levels and could
destroy the producers. If decomposers are removed, the dead animals would pile up due
to which the environment would become polluted. In addition to this, if dead animals
will not decompose, the recycling of nutrients in the soil will be stopped and its fertility
will be reduced. As a result the green cover of the earth will be lost. Thus to maintain the
balance of the ecosystem the presence of organisms is necessary at each trophic level.
