Food: where does it come from? - class-VI

The yeast Saccharomyces cerevisiae, also known as brewer's yeast, is used for fermenting malted cereals and fruit juices to produce ethanol (ethyl alcohol). Microbes (yeasts in particular) have been used for the production of beverages, such as wine, beer, whisky, brandy and rum. 

Herbivores are animals that feed exclusively on plant matter.

Consumers that feed on tertiary consumers are at the fourth trophic level. These are defined as quaternary consumers.

Hawks, lizards, owls, and cats are carnivores that feed on primary consumers (herbivores). Therefore, they are classified as secondary consumers.

Herbivores are the kind of animals whose diet comprises of solely plants. There are different types of herbivores. They further divide into the category of insect herbivores and mammalian herbivores. Mammalian herbivores are found in abundance. They include cows, deer, horses, sheep and more. Hence, correct option is B.

Cats are carnivores, meaning they require meat in their diet and need little carbohydrates. In the wild, cats usually prey on small animals, such as mice and birds. 

Viviparous animals are those animals which give birth to live offsprings. For example, cat, sheep, human, rabbit, etc. Oviparous animals are those animals which lay egg outside. There is little or no development of offspring within the mother. For examples, amphibians, birds, insects.

Humans consume both plant-based and animal-based foods. This dietary habit classifies them as omnivores.

Omnivores have a more diverse diet than herbivores or carnivores, requiring a wider array of enzymes to digest various substrates like cellulose, starch, and proteins. This leads to a higher diversity and number of metabolic enzymes.

Margose (bitter gourd) contains compounds that act as antifeedants, discouraging insects from consuming the plant. The other options are not primarily known for this property in the same context.

Organisms that feed on dead organic matter are known as scavengers or detritivores. Scavengers specifically feed on the remains of dead animals.

Cultigens are plants that have been deliberately selected or modified by humans through cultivation. They rely on human intervention for their survival and propagation.

Humans are biologically classified as omnivores because they possess the physiological capacity to derive nutrients from both plant and animal sources.

Detritivores are organisms that feed on detritus, which includes organic material from various sources including plants and animals. Omnivores are often included in broader ecological classifications of feeding habits.

Macro consumers are heterotrophic organisms that ingest other organisms or organic matter, which includes herbivores, carnivores, and omnivores.

Animals that feed on herbivores are primary carnivores, which occupy the secondary consumer trophic level.

Good food has a balanced diet that helps to maintain or improve overall wealth. It provides all the essentials nutrients to the body and helps the body to have good height, good weight and good strength.

Spices are those substances that are used in flavouring food, coloring and preservation of food. They are mainly used in the flavouring of food items. Some examples of spices are clove, pepper, fennel, chilli, ginger, saffron etc.

Honey is made from the flower nectar collected by the bees , which gets broken down into simple sugars stored inside the honeycomb . 

The brinjal (eggplant) is botanically classified as a berry, which is a type of fruit.

The carrot is a root vegetable, usually orange in colour, though purple, black, red, white, and yellow cultivars exist. It is a modified tap root, for storage.

Peacocks have a very attractive tail and they use their beautiful tail for attracting the peahens. Hence are used as an ornamental animal i.e. in the zoo. On the other hand, Turkey is large birds with nutritious meat. 

Asafoetida is a herbaceous plant of the Umbelliferae family. It is oleo gum resin obtained from the rhizome and root of the plant. This spice is used as a digestive aid, in food as a condiment and in pickles.

Wheat is a grass widely cultivated for its seeds. Wheat is produced from the seeds of the plants. 

Berseem (Trifolium alexandrium) is an annual leguminous fodder crop. It is suitable fodder crop for areas below 1700m altitude with irrigation facilities. It is grown under area with highest water table. Lucerne (Medicago sativa) is a perennial leguminous fodder crop for unirrigated areas including low, medium and high hills of the state. It has good vegetative growth almost throughout the year except during heavy rains or when temperature is below freezing point.

Man is an example of omnivorous animal because Omni means all and vore means eater. An organism which can feed on the plant, as well as the meat of the animal, are called omnivorous.

Humans consume both plant and animal matter, which classifies them as omnivores.

Omnivorous is an animal or person that eats a variety of food both plant and animal origin.

The first torphic level contains the producers which are plants.

Herbivores depend on plants for their nutrition and are hence known as primary consumers and they cannot synthesize their own food.

Herbivores are animals that feed exclusively on plant materials.

Ruminants are exclusively herbivores.

Rice and other foodgrains are agricultural products derived from crops, which are plants. They are primary producers in the food chain.

Inorder to feed a largely populated country like China, the food resources should be easily cultivated and nutritionally rich. 

 Breeds which have the higher capacity for milk production are called milch breeds. The milk producing female livestock animals are called as dairy animals or milch animals e.g., cows, buffaloes, goat and sheep. Thus, the correct answer is option D.

Oil/ ghee can be extracted from both animal products and plant products. Ghee is prepared from boiling and clarifying the milk fat. Hence, it is extracted from an animal source. Vegetable oils are extracted from various seeds like groundnut, soybean and flowers like sunflower of plants. Hence, it is extracted from a plant source. 

Meat and pork are animal products obtained from livestock. They are not derived from plants.
