Answer (1)
Biosphere is the world of living things on the planet, which makes use of the environment around it.
The relationship between living and non-living things in the environment is called an ecosystem .
Green plants make their own food and are called producers . This is because they use sunlight to conduct photosynthesis and create energy-rich food.
We cannot make our food and have to depend on plants and other animals, so we are called consumers . Consumers need to eat other organisms to obtain energy.
Biodegradable substances are harmless to our environment because they can be transformed into a harmless natural state by organisms.
Pollution is the process of making our environment unhealthy and dirty. It’s caused by the introduction of harmful materials like pollutants to the natural environment.
The unidirectional flow of energy in the form of food from one organism to another is called a food chain . This represents how energy moves through an ecosystem from producers to consumers.
Habitat is a surrounding or a house of a particular plant or animal. It provides the necessary conditions for life, such as food, water, shelter, and space.
Waste and sewage should be protected from mixing or flowing with our natural water resources, to make ourselves survive happily. Proper treatment of waste prevents water pollution and protects water quality.
There are biotic, abiotic , and cultural components of our environment. Biotic refers to the living parts of the environment, abiotic to the non-living physical and chemical aspects, and cultural refers to human influences.
