Flow of Energy in an Ecosystem
Sun is the only source of energy in the biosphere. Every living being can get its share of energy through food only and the energy is directly or indirectly obtained from green plants only.
Modes of Reproduction
Two organisms- male and female are essential for sexual reproduction. Now let us study some basic methods of reproduction in single organisms.
Plants that survive under hardships
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.
Gobar Gas Plant in Barsana generates 300 units per day
The engineer couple of Chandigarh, Punjab has established a biogas plant in Barsana. From this plant about 300 unit electricity is generated per day. It is through this electricity that fourteen tube wells are run in the Goshalas.
Land Pollution -Sources and Prevention
Some environmentalists define land pollution as – build up of toxic chemical compounds, salts, pathogens or radioactive materials in soil that can affect plant and animal life adversely, is called as soil pollution.
Animal body parts and sense organs
Most animals of the same kind have same body parts. But their body parts differ in size, shape, colour and functions.
Crafts and their cultural importance
India has a vibrant tradition of crafts. Though agriculture employs largest number of people in this country, craft section employs and sustains over twenty million people.
Important Processes of Reproduction
When both the ovaries are fully mature, they alternatively produce ova at the interval of 28 days. Release of ovum into the uterus through the fallopian tube is called as ovulation.
Food Production from Animals
The government have initiated a number of measures to increase the productivity of milch animals. It has resulted in an increase in the milk production significantly from the level of 102.6 million tonnes at the end of the tenth plan (2006 -2007) to 127.9 million tonnes at the end of the Eleventh plan (2011 -2012. The Annual Growth Rate of milk production was about 5% in 2011 -12 compared to 2010 -11.
Exotic and Introduced Plants
Some propagules or seeds incidentally travel long distances and reach to other county. There they germinate and produce new plants.
Energy for us
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.
