Many ferns grow along north or west facing walls every year. Their spores might have been there in crevices during the dry season. Unless there is a supply of water from leaking pipe they complete their life cycle within the rainy season and pack up with the passing rains. They pass away and leave for us a lesson to remain happy and survive in hard conditions.
The South West Monsoon is ready to go in a delayed manner. It is returning late continuously since last three years.
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.
It is said that corporations can destroy the world’s intact forests. They have also the Power to help save them. They can make an impact by introducing zero- deforestation policies. These policies require suppliers to produce commodities such as timber, beef, palm oil, and fibres for paper in such a way that has a minimal impact on natural forests and climate. These can also introduce paper procurement policies that set ambitious targets to maximise the use of post-consumer recycled wood, pulp, paper and fibre in their products and ensure that any virgin fibre used is certified by a rigorous third-party certification system.
Students of the Department of Engineering in Chowdhari Charan Singh University, Meerut,India, have developed specific unit to process the in campus waste and turn it into manure. The garbage treatment Unit is called as Garbage Clinic by them.
A population is a group of individuals (all members of a single species) who live together in the same habitat and are likely to interbreed. Each population has a unique physical distribution in time and space. It may contain individuals of different ages, and its size (density) is likely to change over time. It grows or shrinks according to the reproductive success of its members.
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.
We rear and take care of animals to take their support in food production. Their systematic and proper rearing and also the arrangement for their proper reproduction and management are called as Animal Husbandry.
Our natural resources are known to have some specific qualities of their own. These qualities are known as natural qualities. It is due to specific natural qualities that different natural resources have been useful to us and to the whole biosphere. But now, the condition has changed considerably. Most of our natural resources like air, water and soil have gone bad due to pollution of different types. What is pollution?
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.
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.
Sida is a shrubby plant which belongs to Malvaceae, a family of flowering plants. It grows in the wild in different types of habitats like overgrazed lands, roadsides; along the sides of walls of old buildings etc.
