  A large area of land covered mainly with trees and plants is called alaust And a large area of grass covered land used for grazing is called grassland There are few trees or places for animals to hide gland habitats. Due to this speal is important for the animals which live in grassland habitats (so they can nits away from their enemies) For most common purposes, however, the wrous forest and and are used in the same sense. The forest (or grassland) is a habitat Many animals such as lon som elephants deer, en live in forest habitats. There are many features of a lion, a deck, other animals and plant which help them to survive in the forest habitat. The adaptations in lion and deer to the forest habitat are described below. Adaptation of lion The lion is a camivorous animal which eats only the meat (or flesh) of oder animals. The lion lives in a forest habitat The adapted to the forest habitat in the following ways: 1.The lion is a strong, fast and agile animal which can hunt and ...

 FATS Like carbohydrates, fats also provide energy to our body. In fact, fats provide us twice as much energy as that provided by the same amount of carbohydrates. For example, a little butter (which is a fat) provides us much more energy than a large slice of bread (which is a carbohydrate). Butter, ghee, groundnut oil, mustard oil, sunflower oil and coconut oil are the common fats used by us in everyday life. Fats are the richest source of energy but they are more expensive than carbohydrates. Since both, fats as well as carbohydrates provide energy, therefore, the foods containing fats and carbohydrates are called 'energy giving foods'. Fats are supplied to our body by many foods such as: Butter, Ghee, Milk, Cheese (Paneer), Oil (Groundnut oil, Mustard oil, Sunflower oil and Coconut oil, etc.), Egg yolk (yellow of an egg), Meat, Groundnut, Cashew, and Soybean. Please note that fats and oils are similar substances, the only difference being that fats are solids at room temper...

 The elements which have a tendency to form positive ions are known metals. The elements which have a tendency to form negative ions are known non-metals. The elements whose properties fall between those of metals and non-metals ore known metalloids. Metals Metals in their pure state, have metallic lustre. Metals are generally hard. • Some metals can be beaten into thin sheets. This property is called f malleability. ⚫ Metals are ductile, ie, thin wires can be drawn from metals. • Metals are good conductor of heat and electricity and have high melting points. Silver and copper are the best conductor of heat. Metals are solid but mercury is liquid at room temperature. . Their oxides are basic. With dil. HCl or H,SO,, they release H₂ gas. e.g., aluminium, copper, sodium, etc Non-metals . These can be solid, liquid or gas at room temperature. . These are neither malleable nor ductile. These are brittle. These do not conduct heat and electricity. C (graphite) is good conductor of elect...
