Question

Answer

Levels of Organization of Biosphere

Organism - Population - Eco system - Biosphere

Organism
An organism is the basic unit of life. It refers to an individual living entity such as a plant, animal, or microorganism. Organisms possess a variety of characteristics that enable them to carry out vital functions such as growth, reproduction, and response to stimuli.

Population
A population is a group of organisms of the same species living in the same geographical area and interacting with each other. This level of organization focuses on the study of the dynamics, distribution, and abundance of a particular species in a given area.

Ecosystem
An ecosystem is a community of organisms interacting with each other and their physical environment. It involves both living (biotic) and non-living (abiotic) components, such as plants, animals, water, soil, and climate. Ecosystems can be terrestrial (land-based) or aquatic (water-based) and are characterized by energy flow and nutrient cycling.

Biosphere
The biosphere is the highest level of organization of the Earth's living systems. It encompasses all the ecosystems on the planet and includes the interactions between living organisms and their physical environment. The biosphere is the sum of all the Earth's ecosystems, and it supports and sustains life in all its forms.

Correct Sequence
The correct sequence of the various levels of organization of the Biosphere is as follows:

Organism - Population - Ecosystem - Biosphere

Starting from the basic unit of life, an organism, we move to populations of organisms of the same species. These populations interact within an ecosystem, which includes both living and non-living components. Finally, all the ecosystems collectively form the biosphere, which represents the entirety of life on Earth.

Therefore, option D, 'Organism - Population - Eco system - Biosphere,' is the correct sequence of the levels of organization of the Biosphere.
