An environment is a place where different things are such as a swampy or hot environment. They constantly interact with it and adapt themselves to conditions in their environment. In the environment, there are different interactions between animals, plants, soil, water, and other living and non-living things. The environment is the total area in which an object or an organism is found. ... The living components include plants, animals and microorganisms while the non-living components include air, water, temperature, soil, etc. These all components are necessary and affect the organisms or objects in one or the other way. Environment plays an important role in the healthy living of human beings. it matters because it is the only home that humans have, and it provides air, food, and other needs. Humanity's entire life support system depends on the well-being of all the environmental factors.

An ecosystem is made up of all the living animals and plants and the non-living matter in a particular place, like a forest or lake. The idea of the web of life is shown by the interdependence within an ecosystem. Animals and plants depend on a complex system of food for survival. A succession of organisms in an ecological community that are linked to each other through the transfer of energy and nutrients, beginning with an autotrophic organism such as a plant and continuing with each organism being consumed by one higher in the chain.

Humans are dependent on nature for many things. Since our emergence on this planet humans have been dependent on nature because humans are part of nature. Humans use animals and plants for food, dig up the ground for sources of energy, cut down trees to build shelter. People depend on plants for food, clean air, water, fuel, clothing, and shelter. Nearly all food webs begin with plants, the primary producers. During photosynthesis, green plants use sunlight to change carbon dioxide from the air and water into simple sugars made of carbon, hydrogen, and oxygen.

Many land animals use their tails to brush away flies and other biting insects. Some species, including cats and kangaroos, use their tails for balance; and some, such as New World monkeys and opossums, have what are known as prehensile tails, which are adapted to allow them to grasp tree branches. Cows use their tails in three major ways—communication, locomotion, and fly removal (response to skin irritation). So the tail is not a useless appendage that should be removed in a cavalier fashion.

When it comes to the main factor that differentiate the two, it is the fact that a nuclear family is small, while a joint family is big.

A joint family is considered bigger compared to a nuclear family because a joint family includes grandparents, uncles, aunts, cousins, and in-laws, aside from the typical mother, father, and children.

When you ask older people, many prefer the joint family, as grandparents help the parents take care of the children. The need to employ a babysitter or nanny to look after the little ones when the parents are working are not necessary in joint families.

On the other hand, a lot of people also prefer a nuclear family. One of the reasons that a nuclear family is ideal to them is because there are less issues happening within the household compared to a joint family, wherein there are many personalities that you need to get along with.

Carbohydrates are the primary energy source for most activity and are burned more efficiently than protein or fat. For example, research has shown that the energy from carbohydrates can be released up to three times as fast as the energy from fat. The main purpose of carbohydrates in the diet is to provide energy. Most carbs get broken down or transformed into glucose, which can be used as energy. Carbs can also be turned into fat (stored energy) for later use. As a fuel, fat could be considered to have several advantages over carbohydrate, but from an exercise perspective it also has several disadvantages. It advantages are that it yields over twice as much energy as carbohydrate (9 kcal v 4 kcal) and that the body potentially has an abundant supply of it.
