(111) Which are the major components of the environment?

(iv) Give four examples of human made environment.

(v) What is lithosphere? (vi) Which are the two major components of biotic environment?

(vii) What is biosphere?​

Answer 1

Explanation:

1. An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue.

2. The term 'natural environment' refers to the non-human-made surroundings and conditions in which all living and non-living things exist on Earth.

3. The basic components of the environment are atmosphere or the air, lithosphere or the rocks and soil, hydrosphere or the water, and the living component of the environment or the biosphere.

Answer 2

1. An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue.
2. The term 'natural environment' refers to the non-human-made surroundings and conditions in which all living and non-living things exist on Earth. ... Ecological units that operate as natural systems (such as soil, vegetation and so on). Universal natural resources (such as air and water).
3. The basic components of the environment are atmosphere or the air, lithosphere or the rocks and soil, hydrosphere or the water, and the living component of the environment or the biosphere.
4. Bridge, roads, buildings, and monuments are four examples of human made environment.
5. lithosphere is the rigid, outermost shell of a terrestrial-type planet or natural satellite. On Earth, it is composed of the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater.
6. Two major components of biotic environment are Plants and Animals.
7. The biosphere is made up of the parts of Earth where life exists—all ecosystems. The biosphere extends from the deepest root systems of trees, to the dark environments of ocean trenches, to lush rain forests, high mountaintops, and transition zones like this one, where ocean and terrestrial ecosystems meet.
