young children in the tropics and Lack of protein in food is the cause of
And why we use it?
The full form of DOTS
is Direct Observation Treatment System. The most cost-effective way to stop the
spread of TB in communities with a high incidence is by curing it.
, ecosystem, biome?
Environment: It is
defined as the sum of total of all the living and non-living things around us
influencing one another.
Ecosystem: A group of
organisms interacting among themselves and with environment for exchanging
energy and matter is known as ecosystem.Ecological
. The progressive replacement of one community by
another till the development of stable community in a particular area is called
as ecological succession.
Species diversity is the diversity between different
species. The sum of varieties of all the living organisms at the species level
is known as species diversity.
Food chain and food web with suitable
.Food Chain : A food chain is a picture or model
that shows the flow of energy from Autotrophs to a series of organisms in an
environment. A food chain only follows just one path as animals find food.eg: A
hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which
has eaten grass.
Example: grass –àdeer-àlion
Food web : A food web
is several food chains connected together. A food web shows the many different
paths plants and animals are connected. eg: A hawk might also eat a mouse, a
squirrel, afrog or some other animal. The snake may eatDisaster

Instruments to measure earthquake?
. Earthquake magnitude
or amount of energy released is determined by the use of a seismograph.
The scale was developed by a
seismologist named Charles Richter (Richter Scale, Range 1-9).
Second type of
scale, the earthquake intensity scale measures the effects of an
earthquake where it occurs.
Landslides are defined as the mass movement
of rock, debris or earth down a slope. They
are influenced by geological, geo-morphological, climatic,
environmental, hydrological and seismological conditions and by biological
.Give the types of tectonics movement?
• . Type of movement along the plate’s boundaries:
– a) pulling away from each other (DIVERGENT)
. It defines the devastating effects that may be caused by an enormous spread
of a certain kind of living organism- that may be the spread off disease, a
virus, an epidemics, but also just a sudden growth of population of certain
kind of plants and animals e.g. Ebola , swine flu
What are the types of cyclone?
Polar low, Sub-tropical, Tropical
)”The study of relationships between living
organisms and the environments in which they live is the science of Ecology.”
. The maximum number of individuals that can be
supported by a given environment .
• A54. Natural resources are naturally occurring
substances that are considered valuable in their relatively unmodified
• Therefore, Natural resources are the materials
required for sustenance of our life
Soil erosion is defined as the movement of soil
components, especially surface layer and top soil from one place to another
The energy harnessed from
the hot rocks present inside the earth is called geothermal energy.
. The energy available due to the difference in
temperature of water at the surface of the oceans and at the deeper levels is
called Ocean Thermal Energy
What is Biomass energy?
Biomass is the organic matter generated by plants or
animals which include crop residues, cattle dung, manure, sewage, agricultural
Resources which can never
exhaust. Once exhausted, they can be replenished by recycling, replacement or
reproduction.E.G SOLAR ENERGY, WIND ENERGY, Geothermal energy
resources are those resources which can restock (renew) themselves if they are
not over-harvested but used sustainably.
A non-renewable resource is a natural resource that
exists in a fixed amount that cannot be re-made, re-grown or regenerated or
replaced after use.e.g coal ,fossil fuel
Climate change refers to any significant change in the measures of climate lasting for
an extended period of time. In other words, climate change includes major
changes in temperature, precipitation, or wind patterns, among others, that
occur over several decades or longer
