### Step-by-Step Solution: 1. **Understanding Symbiotic Relationships**: - Symbiotic relationships occur when two different species live closely together, often benefiting from each other. In this context, we are focusing on organisms that indicate pollution levels. 2. **Identifying the Organisms**: - The organisms that serve as pollution indicators are called lichens. They are a unique combination of two different organisms: a chlorophyllous member and a non-chlorophyllous member. ...

Food chains and the energy flow within an ecosystem provide an important understanding of contingencies and mutual dependencies of organisms. The given below flow chart depicts the energy flow within some members of a grassland ecosystem. The grass in the below ecosystem transducer 120,000 J of sunlight and fixes it into 12,000 J of energy. It is established that 90% of the energy of one trophic level is not passed to the next trophic level. Further assume that the energy transferred from one trophic level to the next is equally shared among the different organisms at that trophic level. Based on the above information, indicate the amount of energy that an organism C may have received from an organism from the previous trophic level.

How wonderful is the living world! The wide range of the living types is amazing. The extraordinary habitats in which we find living organisms, be it cold mountains, deciduous forests, oceans, fresh water lakes, deserts or hot springs, leave us speechless. The beauty of a galloping horse, or a migrating bird, the valley of flowers or the attacking shark evokes awe and a deep sense of wonder. The ecological conflict and cooperation among members of a population and among populations of a community or even a molecular traffic inside a cell make us deeply reflect on - what indeed is life ? This question has two implicit questions within it. The first is a technical one and seeks answer to what living is as opposed to the non-living, and the second is the philosphical one, and seeks answer to what the purpouse of life is. What is living ? When we try to define 'living', we conventionally look for distinctive characteristics exhibited by living organisms. Growth, reproduction, ability to sense environment and mount a suitable response come to our mind immediately as unique features of living organisms. One can add a few more features like metabolism, ability to self-replicate, self-organize, interact and emergence to this list. Distinctive characteristics exhibited by organisms indicate that
