Answer:

any time a source of energy is obtain using natural means, the 10 % rule will apply. 10 % rule means when energy is passed in an ecosystem from one trophic level to next, only 10% of the  energy  will be passed on. A trophic level is the position of organism in the food chain.

So Quaternary consumers are at the top position in the food chain, they will receive less energy from the food as compared to the primary consumers which are at the bottom of the food chain. so when getting less food and less energy, Because of this, the populations of Quaternary consumers are usually the smallest out of the populations in the food chain.

For each of the following, circle the word that does not belong belong with the rest and then in ONE complete sentence, explain
Vika [28.1K]

Answer: the words that doesn't belong include:

1.) Power

2.) Deforestation

Explanation:

1.) Coal, Oil, Solar and Natural Gas are considered to be sources of energy while POWER is not considered among the rest this is because it's energy in action and not a source of energy.

Coal, oil and natural gas are known as fossil fuels which are the most common sources of energy in industries and homes. These fossil fuels are destroyed by use, that is, they cannot be recovered. Alternative sources of energy is the solar which is gotten from the sun energy. Although not considered a very efficient energy producer, there are already discovered schemes that would provide us with an inexhaustible supply of energy which would also not cause any pollution problems.

2.) Biodegradable, Recycling and Sustainability are means by which pollution is being avoided in the environment. While DEFORESTATION is a process that can cause pollution of an environment, therefore it doesn't fit into the rest of other words.

Biodegradable materials can be broken down by microorganism. Examples include human and animal excreta. Recycling is the reprocessing of waste materials in order to be re-used. This reduces the amount of waste that are sent to incinerators. While sustainability is the maintenance of the ecosystem to remain diverse and productive over time. This could be seen in the preferred use of renewable energy over non renewable energy. But deforestation is the massive cutting down of trees which can cause soil erosion and climate changes leading to the pollution of the environment.

O que a china pode fazer para evitar o estresse hidrico?
irina1246 [14]

Answer:

Explanation:

water stress is used to describe a scenario in which, in a given region, the demand for water is greater than its availability and capacity for renewal. In this type of situation the amount of water available is insufficient to meet the needs of use. A country is considered to be under water stress when water availability is less than 1,700 m 3 per capita per year, according to the UN.

Among the main causes of water stress are: water wastage; population growth and intense urbanization with a consequent increase in the consumption of water for domestic, industrial, agricultural and livestock purposes, among others; water pollution by the discharge of sewage, solid waste, industrial waste and chemical products from agricultural activities; global warming , which directly affects the water cycle ; inequalities in water distribution and poor supply systems.

Water stress is a reality in many regions of the world and it is estimated that in a short time many other places will be part of this scenario. UN data reveal that by 2025 about two-thirds of the world's population will be living under conditions of water stress. Some regions have even reached the water shortage, such as the Middle East . Among the regions hardest hit by water stress are North Africa , Mediterranean (European and African), Southeast Asia, Northeast China, Australia, United States and Mexico.

Population growth and economic development are the main factors contributing to the increase in water consumption in the world. With this, the amount of water consumed per capita grows more and more, but the amount of this resource on the planet remains unchanged. Most of this economic growth occurs in developing regions, such as Africa and Asia, which already tend to lack water availability. In the case of developed countries, the problem is different: improving living conditions means that per capita water use increases.

With regard to water availability, Brazil is a privileged country, presenting approximately 12% of the world's fresh water. However the distribution of this resource is extremely unequal, with about 68% concentrated in the North region. The Southeast region has only 6% of the country's freshwater reserve. In other words, the most populous regions have the lowest water availability. The Northeast region suffers the most from water stress, since it is the most arid in the country, passing through long periods of drought .

The impacts caused by water stress are many, from environmental and social problems to political and economic ones. It is also worth mentioning the possibility of wars, which had previously occurred only in the case of land, oil or other resources. Possible solutions to avoiding the continuity of the water crisis include the use of technologies that consume less water in irrigation, conscious consumption of water, avoidance of water pollution, waste management and effluent treatment efficiently , improve supply networks, and government action to establish laws and incentives that encourage everyone to realize that water is a limited resource.
