explain the global water crisis in your own words​

Answers

Explanation:

Water is the basic necessity of every human being. But, water scarcity is a major issue that is rising very rapidly in modern-day India. The problem has become so severe that in many states the groundwater has almost dried up and people have to depend on water supply from other sources. In addition, water is one of the most misused commodities that we still waste. It is the central point of our lives but not the central point of our focus.

In the past, people understand the value of water and plan their lives around it. Moreover, many civilizations bloom and lost on account of water. But, today we have knowledge but we still fail to understand the value of water.

Reason for Water Scarcity in India

Water scarcity is the cause of mismanagement and excess population growth of the water resources. Also, it is a man-made issue that continues to rise. Besides, some of the reasons for water scarcity are:

Wasteful use of water for Agriculture- India is one of the major food growers in the world. That produces tons of quantity of food to feed its population and export the surplus that is left.

In addition, producing this much food requires a lot of water too. The traditional method of irrigation wastes a lot of water due to evaporation, water conveyance, drainage, percolation, and the overuse of groundwater. Besides, most of the areas in India use traditional irrigation techniques that stress the availability of water.

But, the solution to this problem lies in the extensive irrigation techniques such as micro-irrigation in which we provide water to plants and crops using a sprinkler or drip irrigation.

Reduction in water recharge systems- Due to rapid construction that uses concrete and marbles do not let the rainwater to get absorbed in the soil. But, if we install some mechanism in our houses that can hold the rainwater then we can recharge the groundwater.

Lack of water management and distribution- There is a need for an efficient system that can manage and distribute the water in urban areas. Also, the government needs to enhance its technology and investment in water treatment. Besides, we should ensure optimization at the planning level.

Solutions to Overcome this Problem

Water-free urinal- Urinal waste around 6 liters of water per flush that add up to 25 thousand liters per year. If a male member of the house stops using the flush then they can save lots of water.

Close the running tap- During dishwashing and hand washing people often let the tap running. These running taps waste thousands of liters of water per year. Besides, closing the tap will reduce this problem.

Replace dripping taps- In India it is commonly seen that most of the houses have one or two taps that drop water even when they are close. This running tap wastes up to 30,000 liters of water that nobody bothers to change. So, we should replace these taps immediately.

To conclude, water scarcity has become a more dangerous problem day by day. Also, due to our leniency that we haven’t taken the problem water scarcity seriously. But, now the authorities and people are working to resolve this problem so that our future generations do not have to buy this necessity.

Nuclear Fission is not a good source of energy. This is by reason of only 0.7% of the uranium being captured. This is small even if one doesn't mention that only 40% of that 0.7% is converted into usable energy. There are also chances that the power plant could explode during conversion. All of this evidence points to the fact that Nuclear Fission and Nuclear Energy themselves should not be relied on.

Which characteristic is common to grasslands, dry woodlands, and shrublands?

b) They have the same terrain.
c) They have the same soil composition
d) They have the same amount of precipitation

Answer:

They rely on fire as part of their renewal.

Explanation:

They rely on fire as part of their renewal. Which option describes the climate of temperate grasslands

They rely on fire as part of their renewal is common in grasslands, dry woodlands, and shrublands.

Grasslands, dry woodlands, and shrublands

Tropical Grassland, Savanna & Shrubland is dominated by grasses and shrubs, with or without scattered trees. Some occur in climates too dry for the forest; others depend on soil conditions or fire, or both, rather than climate. The structure is a single, major grass or shrub stratum, or a mix of the two, with trees typically <10% cover, rarely with bare ground.

Thus, we can conclude that grasslands, woodlands, and shrublands depend on fire they have these common characteristics.

If you see signs of life such a holes in trees, tracks, and nests, you may estimate the population size using which method?

Answers

Answer:

INDIRECT METHODS

Explanation:

To estimate population density there are two possible methods: Direct methods and indirect methods.

Abundance indexes are the parameters related to density, and they reflect changes that might happen in the target population density. They are commonly used to compare population sizes, for instance, the abundance of an insect species during the winter and the summer. These indexes are easy to get, so it is possible to make many estimations and make statistical analyses to detect differences.

There are two types of abundance indexes:

The ones based on direct observation and/or captureDIRECT METHODThe ones based on traces and frequenciesINDIRECT METHOD

INDIRECT METHODS:

When talking about traces, we are referring to any mark or evidence left by animals, such as footprints, holes, feces, sediments, hair, marks, pathways, nests, shelters, dead bodies, food leftovers, songs, noises, among many others. Traces are directly related to population abundance.

The advantages over the indexes that use capture and observation are that traces are not influenced by detectability, they are much easier to use, cheaper, and they turn to be significant with less visible species.

The paths are useful, but they last for a long time in the habitat, so they do not entirely reflect the recent presence of the animal in a specific moment. However, on the paths, there can be other traces such as footprints, hair, and others that are easier to identify and which reflect a recent pass. These can be used to determine abundance.

In shy species, the alternative to evaluate abundance is to constate their presence in a sampling unit, this is, their frequency. Frequency can be used as an abundance index and, under certain conditions, might be statistically tested to evaluate abundance differences.

An organism's body weight is a balance between: the energy carried in the food we eat and the energy burned in digesting that food. the energy burned during growth, reproduction, and movement and the energy carried in the food we eat. the energy an organism spends on growth and the energy an organism invests in reproduction. the energy stored as lipids within the body and the energy burned during all activities. the energy carried in the food we eat and the energy burned by our basal metabolic rate.

Answers

Answer:

the energy burned during growth, reproduction, and movement and the energy carried in the food we eat.

Explanation:

A good health can be defined as the state of well-being in which all of the components of an individual's health are in balance. These state of well-being comprises of six (6) important components and they are; physical, spiritual, emotional, environmental, social and mental or intellectual. In order to have a good health, physicians and medical professionals advise individuals to engage in physical activity such as an aerobic exercise.

An aerobic exercise refers to all forms of physical activity that an individual engages in, in order to increase the heart rate (from low to high intensity) in response to the level of oxygen required by any activated or working muscle in the human body.

Some examples of aerobic exercise (cardiofitness activity) includes cycling, swimming, jogging, walking, skiing etc.

Generally, fitness experts usually advises everyone to judiciously engage in cardiofitness activities or exercises so as to improve well-being, body mass index (BMI), wellness or heart health.

Hence, the body weight of an organism is simply a balance between the energy burned during growth, reproduction, and movement and the energy carried in the food we eat.

This ultimately implies that, an organism's body weight is the difference between the energy that is taken in and the energy expended or burn throughout body activities.
