              All aspects of our lives are impacted by the environment we live in, and our daily actions have an impact on the
              environment as well. Cities are dependent on nearby villages for their food supply, and these communities in
              turn depend on woods, meadows, rivers, and seashores for resources like water, fuel wood, fodder, etc. These
              resources,  derived  from the  interconnected  web  of  life formed by  plants  and  animals, sustain our  existence.
              Similarly, our  school environment is composed of both  physical and  sociocultural dimensions.  The physical
              environment encompasses the school building, classrooms, library, laboratories, corridors, kitchen, toilets, garden,
              and playground—a backdrop essential to our educational pursuits and daily routines. In parallel, the sociocultural
              environment within our school is shaped by various factors. It includes the quality of teaching and learning climate
              established by educators, the diversity of student activities, inclusivity  and respect for diversity, enriches our
              learning experience and community dynamics. These elements together create a supportive environment where
              learning thrives and students grow.
              A balance in the environment is essential for the existence of a healthy life on this earth. Humans constantly interact
              with it in direct or indirect ways. Sometimes this interaction is biased and disturbs the balance of this mother earth,
              resulting in changes that affect all. We all need to understand its importance and work in the direction of saving
              it from all possible ways of destruction. In this chapter, we will learn some important facts about our environment
              and its relationship with society.

                       Ecosystem

              An ecosystem is defined as a community where living and non-living things interact with each other and their
              surrounding environment to form a balanced system. Any imbalance in any of the components will disturb the
              whole ecosystem, which might create problems in the existence of other living organisms.
              It is made up of two important components:
                 • Biotic: It refers to living organisms of the ecosystem which can be plants and animals. Plants are considered
                to be autotrophs which make their own food by trapping energy of the sun. This energy flows through all the
                other living components when plants are consumed by plant eating animals which inturn are eaten up by other
                bigger animals.
                 • Abiotic: Abiotic components are the non-living components of an ecosystem. It includes air, water, soil, minerals,
                sunlight, temperature, nutrients, etc.
              There are two main types of ecosystem:
                 • Terrestrial: A terrestrial ecosystem is a community of living and non-living things on land. They live, develop
                and interact with each other in soil and air around them. It includes forest, grassland, desert, etc.
                 • Aquatic: An aquatic ecosystem is a community of living and non-living things in water. They live, develop and
                interact with each other in water around them. It includes marine and freshwater ecosystems.
