They are often interdependent on each other as well. These relations of dependence and

living organisms with each other, and with the physical and chemical factors of the
environment in which they live.
(ii) The environment that consists of all objects created by nature is called natural
environment. The natural environment comprises land, water, air, plants and animals.
(iii) The major components of environment are natural environment (consists of all
objects created by nature), human environment (consists of human beings) and human-
made environment (consists of objects created by human beings).
(iv) Parks, buildings, roads and industries are some examples of human-made
environment.
(v) Lithosphere (or the domain of land) is the solid crust or the hard top layer of the
Earth. It is made up of rocks and minerals, and is covered by a thin layer of soil. It is an
irregular surface with various landforms such as mountains, plateaus, plains and valleys.
(vi) The two major components of biotic environment are plants and animals.
(vii) Biosphere is the narrow zone of the Earth where land, water and air interact with
each other to support life.

(i) Man modi�es his environment
(ii) Plants and animals depend on each other
Answer. (i)All living organisms depend on their immediate surroundings or
environment. Human beings interact with their environment and modify it according to
their needs. The primitive humans lived a simple life, and ful�lled their needs from the
nature around them (by hunting, eating fruits, living on trees and in caves, etc.). With
the progress of time, as life grew more and more complex, humans learnt newer ways to
use their surroundings (growing crops, raising animals, setting up permanent
settlements, etc.), for satisfying their growing needs. The discovery of �re, the invention
of the wheel, the emergence of the barter system, the development of trade and
commerce, the invention of the engine, the industrial revolution and the advancements
in transportation and communication are some of the milestones on the road of human
growth. While travelling on this road to development, humans have constantly modi�ed
all the three components of environment—natural (polluting the air by burning fuels),
human (forming political and religious units) and human-made (using telephones lines
for internet connectivity).
(ii) Not only are all plants, animals and human beings dependent on their environment,
but they are also interdependent upon each other in several ways. For example, plants
are eaten by animals as food. Through photosynthesis, plants produce oxygen, which is
necessary for the survival of all living organisms. Forests are the natural habitats of wild
animals, while the woods of trees are used by humans for various purposes like building
houses, boats, furniture, etc.
On the other hand, animals help plants reproduce by helping in the pollination of seeds.
Nitrogen is essential for the survival of plants, and they are provided with this nitrogen
by the bacteria that live in the soil and in the roots of some plants. Photosynthesis,
which is the way by which plants make their food, depends upon factors like sunlight,
water and carbon dioxide. The carbon dioxide is provided by humans and animals
through respiration.
