FREQUENTLY ASKED
QUESTIONS
Q. What is
Ecology?
Ans. The study of
the relationships between organisms and their environments,
including, interactions of living organisms with one another and
with their non-living surroundings, the flow of matter and energy
in an environment, and the structure and functions of nature.
Q. What are the
components of environment?
Ans. There are
two environmental components: Abiotic and Biotic.
Q. Define
Environmental Conservation.
Ans. It means
protection of living organisms and natural resources from
continuous
exploitation. It is divided into two categories:
In-situ
Conservation
: The
conservation of components of biological diversity within their
natural habitats.
Ex-situ
Conservation:
Pertaining to study or
maintenance of an organism or groups of organisms away from the
place where they naturally occur. Commonly associated with
collections of plants and animals in storage facilities, botanic
gardens or zoos.
Q. Define
sustainable development.
Ans. Sustainable
Development is the development that meets the needs and aspirations
of the current generation without compromising the ability to meet
those of future generations.
Q. What are
natural resources?
Ans.
Natural resources are the raw materials that occur naturally within
environments and exist undisturbed in past by human activities.
Q. What are
renewable resources?
Ans. These are
the natural resources which are replaced by natural processes and
there is no danger of a lack of long-term availability. Examples of
renewable energy resources are solar radiation, tides, winds and
hydroelectricity. Some other resources are wood, paper, and
leather.
Q. What are
non-renewable resources?
Ans. These are
the natural resources which cannot be produced, re-grown,
regenerated, or reused. These resources often exists in a fixed
amount (stock) in various places in the earth's crust and has the
potential for renewal only by geological, physical, and chemical
processes taking place over hundreds of millions to billions of
years. Examples of nonrenewable resources are fossil fuel (such as
coal, petroleum and natural gas) and nuclear power. In contrast,
resources such as timber (when harvested sustainably) or metals
(which can be recycled) are considered renewable resources.
Q. What are
fossil fuels?
Ans. Fossil fuels
are formed due to the partial or complete decomposition of organic
material as a result of exposure to heat and pressure in earth's
crust over millions of years. e.g. crude oil, natural gas, and coal
etc.
Q. What is global
warming?
Ans. The term
given to the possibility that Earth's atmosphere is gradually
warming because of the greenhouse effect of carbon dioxide and
other gases. Global warming is thought by many to be the most
serious global environmental issue facing our society.
Q. What is the
difference between climate and weather?
Ans. The
difference between weather and climate is a measure of time.
Weather is what conditions of the atmosphere are over a short
period of time. it is not the same everywhere and includes events
humidity, rainfall and temperature. Climate is the average weather
pattern in a place over many years.
