Given below is a table. Fill in the gaps.
Property Simple diffusion facilitate transport Active Transport Property simple diffusion facilitated transport Active transport. Highly selective _________ Yes _____________, Uphill transport ______ _________ Yes, Requires ATP----- ------- -----.

Smaller, lipid soluble molecules diffuse faster through cell membrane, but the movement of hydrophilic substances are facilitated by certain transporters which are chemically________

Various types of transport mechanisms are needed tofulfill the mineral requirements of a plant. Why are they not fulfilled by diffusion alone?

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. Draw a simple food chain to show transfer of carbon from plants to decomposers.
