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.
Fern species that grow on old walls in
Ferns belong to Pteridophytes and grow on high altitudes in moist cold places. These don’t need any fertile soil. Since Ranchi or the most part of Jharkhand is located on high land its climate is rather different and somewhat similar to those area of mountains. The author reports here the two fern species that preferably grow in this region that too on old walls.
Bringing Our Farmers Back to the Land in India
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.
Two Types of work
Works done inside houses include works related to livelihood, child rearing, some small scale industries, human services, office works and indoor plays etc
Plant Movements
Growth and movements in plants occur due to internal and external factors. Plant hormones are internal factors while light, touch, gravity and other stimuli are external factors that affect plant growth and movements.
Biodiversity, Its Concept, Values, Loss, and Causes of Loss
An association of all the plants at a particular place is called a Plant Community and the association of all the animals at the same place is called an Animal Community. Both the plant and animal communities inhabit a particular place living completely merged and interacting among them. Members of a community not only interact with the members of other communities, they interact with the members of their community and with the physical environment around them, as well.
How does energy flow through an ecosystem?
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.
What is Ozone layer? How is it depleted and what are the control measures?
Ozone absorbs ultraviolet radiations so that much of it is never allowed to reach to the earth surface. The protective umbrella of ozone layer in the stratosphere protects the earth from harmful ultraviolet radiations. Ozone plays an important role in the biology and climatology on the earth’s environment. It filters out all the radiations that remain below 3000Å. Radiations below this wavelength are biologically harmful. Hence any depletion of ozone layer is sure to exert catastrophic impacts on life in the biosphere.
Interactions between members of a species
Living beings interact among themselves in the same species, with the members of the other species, and with the components of the abiotic environment in an ecosystem. Interaction between the members of the same species is called as Intraspecific whereas the interaction among individuals of different species is called as Interspecific.
Habitat Destruction and Loss of Water Bodies
The predominant features that create structural complexity in the environment, such as plants or animals are called as a habitat.
A process, in which natural habitat is rendered functionally unable to support the plants and animals occupying it, is named as Habitat destruction. In the process of habitat destruction, plants and animals that previously used the place are displaced or destroyed, reducing biodiversity.
Restrictions on Play for girls
In early society, girls were restricted from play. They were restricted inside homes. This was something to do with our social conditions and traditions. But, girls are being given more rights today than they had earlier.
