Anything from which we can derive energy is called as a source of energy. Since all the life processes need energy, energy is most important for our survival.
Our body derives energy from the food we eat. Thus, the food we eat is the source of energy for our body. But this is not the whole story. We need energy for our growth and economic development as well.
Consumers too utilize some energy in their metabolic processes. Under these conditions some energy escapes away in the form of their body heat and some energy is wasted through excretory matter from their bodies. The rest of the energy goes into the atmosphere when top consumer dies and its body is decomposed.
Energy is essential for working and survival of all the organisms on this planet. In fact, it is the energy which enables organisms to perform their biological functions.
Ocean is a vast natural resource of water. These have also been examined in the search for alternate sources of energy-generation. For example, gravitational pull, by sun and moon causes tides, in which sea level rises and falls, two times in 24 hours. When it rises, sea water may be diverted through suitable channels, to inshore reservoirs driving the turbines, during its entry.
Ever since the earth was inhabited, humans and other life forms have depended on things that exist freely in nature…
About 1000J radiant energy comes to the earth from the sun. Out of this, only 10% of the total energy is used up by green plants in the process of Photosynthesis. Remaining 990J of energy escapes away into the atmosphere. 10J of energy is stored in the form of chemical energy in starch and sugars.
Energy is the basic force capable of running life. But, the sources of energy are running short.
Fried and roasted food rush into our memory today because lock down has locked us inside. As a result the forgotten dishes are now being served on the table. Stuffed brinjal, stuffed lady’s finger, stuffed Shimla mirch, parval etc. taste double when fried. The maincourse items that were long banned in the kitchen are occupying their places on the dining table.
Non-renewable resources coal and petroleum are energy sources that we use and consume faster than the rate of their production in nature.
Due to less paying agriculture farmers migrated to cities. The volume of migration was seen during the lock down period when farmers left cites for remigation. Remigrated farmers can be checked to their fields by improving pricing and free maket system to farmers.
We have many types of butterflies around us. These are good pollinators of crop plants and grass pollinators. Theecotrends lens has some images of these pollinators
Both pomegranate and mango are nutritios fruits. These help us in keeping good health.
