In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain. Food webs consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems.

Can anyone give a paragraph answer to what global footprint means! Thank you.
pochemuha

Answer:

The ecological footprint is a method promoted by the Global Footprint Network to measure human demand on natural capital, i.e. the quantity of nature it takes to support people or an economy.[2][3][4] It tracks this demand through an ecological accounting system. The accounts contrast the biologically productive area people use for their consumption to the biologically productive area available within a region or the world (biocapacity, the productive area that can regenerate what people demand from nature). In short, it is a measure of human impact on the environment.

Footprint and biocapacity can be compared at the individual, regional, national or global scale. Both footprint and biocapacity change every year with number of people, per person consumption, efficiency of production, and productivity of ecosystems. At a global scale, footprint assessments show how big humanity's demand is compared to what Earth can renew. Global Footprint Network estimates that, as of 2014, humanity has been using natural capital 1.7 times as fast as Earth can renew it, which they describe as meaning humanity's ecological footprint corresponds to 1.7 planet Earths.[1][5]

Ecological footprint analysis is widely used around the world in support of sustainability assessments.[6] It enables people to measure and manage the use of resources throughout the economy and explore the sustainability of individual lifestyles, goods and services, organizations, industry sectors, neighborhoods, cities, regions and nations.[2]

A nurse who is preparing to boost a client up in bed instructs the client to use the overbed trapeze. which risk factor for pres
atroni [7]
I will try my best to answer your question

Shearing forces-rationale: friction, impaired circulation, localized pressure, and shearing forces are all risk factors of pressure ulcer development; trapeze use reduces shearing forces. shearing forces (opposing forces that cause layers of skin to move over each other, stretching and tearing capillaries and, eventually, resulting in necrosis) can occur as clients slide down in bed or are pulled up in bed. subcutaneous skin layers adhere to the sheets while deeper layers, muscle, and bone slide in the direction of movement. to reduce shearing forces, the nurse should instruct the client to use an overbed trapeze, place a draw sheet under the client to move him up in bed, and keep the head of the bed no higher than 30 degrees.client needs category: physiological integrityclient needs subcategory: basic care and comfortcognitive level: applicationreference: taylor, c., et al. fundamentals of nursing: the art and science of nursing care, 6th ed. philadelphia: lippincott williams & wilkins, 2008, p. 1196.

When we make inferences about one population proportion, what assumptions do we need to make?.
arlik [135]

Answer:

It is necessary to make the following assumptions when making inferences about a group of people based on a sample of subjects drawn from that group:

  • Data is quantitative in nature.
  • A sample size of 30 or more is required.
  • The data set must consist of a simple random sample.
  • A Normal Distribution must be present in the data.

The data must come from a sample that isn't all the same size so that it can be generalized well.

The sample size must be at least 30 or more, according to the central limit theorem.

Mean and standard deviation are two examples of quantitative data from which statistical conclusions can be drawn.

To avoid bias, the sample size should be increased rather than the distribution skewed.
