Answer the following Read the paragraph and answer the questions given below it. A biotic carbon atoms are circulated into the biotic form through processes like photosynthesis and respiration. Green plants convert carbon dioxide into carbohydrates and also produce carbon compounds like proteins and fats. Biotic compounds are transported from plants to apex consumers through intermediate trophic levels. After the death of all types of consumers, carbon is recycled by biotic decomposition. The carbon recycled in this way goes into the atmosphere and can be taken up by living organisms thus ensuring circulation and recycling of carbon in the biosphere. What process plays a significant role to ensure that carbon is available to living organisms even after the death of apex consumers?

Read the paragraph and answer the questions given below : Locomotion is considered as an important characteristics of the animals. However, animals belonging to Porifera are said to be sedentary. Every other phylum has typical locomotory organs. E.g. Nereis crawls with the help of parapodia, whereas earthworm buries in soil by setae. Spiders have four pairs of walking legs, crab has five while all insects have three pairs of walking legs. The walking legs are also called appendages. Starfish moves with the help of tube feet. Snails and bivalves use muscular foot for locomotion. Birds flying with their spread out wings and fish swimming with their fins, both have spindle-shaped body tapering at both the ends. While flying or swimming such body offers least resistance during locomotion. Mammals have two pairs of limbs while animals like snakes are limbless. Other animals belonging to the class of snakes also have very weak limbs.which make them creep on the ground. Answer the question: Which the locomotory organ of animals belong to Phylum Mollusca?

Select the appropriate option and complete the following paragraph. (cornea, faint, conical, rod, image, coloured, retina, colours, myopic, presbyopic, colour blind) The ____ in our eyes consists of many light sensitive cells. These cells are shaped like a rod and like a cone. The ____ shaped cells give information about the intensity of light to the brain. The ____ cells give information about the colour of the object to the brain. Brain processes all the information received and we see the actual image of the object. Rod shaped cells respond to ___ light also but conical cells do not. Thus we perceive ____ only in bright light. Some people cannot recognize few colours or cannot distinguish between different colours. These persons are said to be _____. Apart from not being able to distinguish between different colours, their eye sight is normal.
