The correct Answer is:
To determine whether the given statements are true or false, we will analyze each statement step by step. ### Step-by-Step Solution: 1. **Statement (i): "The shift from grain to meat creates more demand for cereals."** - **Analysis**: When there is a shift from grain consumption to meat consumption, it implies that more livestock is being raised for meat production. Livestock, such as cattle, require a significant amount of grain as feed. Specifically, to produce 1 kg of meat, approximately 3 to 10 kg of grains are needed to feed the animals. Therefore, as the demand for meat increases, the demand for cereals (grains) also increases to support the livestock. - **Conclusion**: This statement is **True**. 2. **Statement (ii): "Spirulina can be grown easily on materials like wastewater from potato processing plants, straw, molasses, etc., to produce large quantities and can serve as food rich in liquid and minerals."** - **Analysis**: Spirulina is a type of cyanobacteria that is often referred to as single-cell protein (SCP). It can indeed be cultivated using various substrates, including wastewater from agricultural processes, straw, and molasses. These materials provide a suitable environment for Spirulina to grow, and it is known for being rich in proteins and essential minerals. This makes it a valuable dietary supplement for both humans and animals. - **Conclusion**: This statement is also **True**. ### Final Answers: - (i) True - (ii) True

Which of the following statements is/are incorrect? (i) Water and minerals, and food are generally moved by a mass or bulk flow system. (ii) Bulk flow can be achieved either through a positive hydrostatic pressure gradient or a negative hydrostatic pressure gradient. (iii) The bulk movement of substances through the conducting tissues of plants is called translocation. (iv) Xylem translocates organic and inorganic solutes, mainly from roots to the aerial parts of the plants. (v) Phloem translocates water, mineral salts, some organic nitrogen and hormones, from the leaves to other parts of the plants.

Which of the following statements regarding eutrophication are correct ? (i) Eutrophication is the natural ageing of a lake by nutrient enrichment of its water. (ii) Pollutants from human activities like effluents from the industries and homes can radically accelerate the aging process of a lake. This phenomenon is called as cultural or accelerated eutrophication. (iii) The plant nutrients responsible for eutrophication are nitrates and phosphates. (iv) These phosphates and nitrates accelerate the growth of algae, which utilise oxygen and may deoxygenate the water to kill the fish and other aquatic animals.
