In the biosphere, living beings are :

Correct option is D

The correct answer is (d) inter-related, as well as inter-dependent on each other.
Living beings in the biosphere are interconnected and interdependent on each other for their survival. This means that they rely on each other for various needs, such as food, pollination, oxygen production, and nutrient cycling. For instance, plants produce oxygen that animals breathe, while animals produce carbon dioxide that plants need for photosynthesis. Decomposers break down dead organisms and return nutrients to the soil, which plants can then use to grow. The biosphere is a complex web of interactions between different organisms, and these interactions are essential for maintaining the balance of ecosystems and sustaining life on Earth.
Therefore, living beings in the biosphere exhibit both interrelatedness and interdependence, highlighting the intricate and interconnected nature of life on our planet.
