how the consumers in one level of the pyramid obtain energy from the organisms at the previous level of the pyramid

Answers

Answer:

by feeding on the organism on the previous level, the consumers at each level will receive energy. However, most of the energy is lost at each trophic level and very little gets transferred from one trophic level to another. Approximately, 10% of the energy is transferred from one trophic level to another.

Explanation:

hence, when a level takes energy from a previous level, the engery transfers but slowly gets less, so some levels get less energy depending on where the engery was located.

Which of the following is not a testable hypothesis that this data could be used to support or disprove?

Answers

Answer:

b

Explanation:

this is because babies needs certain nutrient to grow faster which includes tallness

The statement that is not a testable hypothesis based on the given data is: being taller is always better than being shorter. Therefore option A is correct.

The given data provides information about the average height of females and males in different age groups. Let's analyze each statement to determine whether it is a testable hypothesis or not:

A. All men who are married are taller than their wives.

This statement cannot be tested using the given data because it only provides average heights for different age groups, but it doesn't provide any information about marital status or the specific heights of individual men and women.

Therefore, we cannot determine whether all married men are taller than their wives based on this data.

B. Height is affected by childhood nutrition.

This statement can be tested using the given data. By examining the average height changes across different age groups, we can infer whether childhood nutrition has an impact on height.

If there is a noticeable trend of increasing height from birth to older age groups, it could suggest a correlation between childhood nutrition and height.

C. Being taller is always better than being shorter.

This statement is subjective and cannot be tested using the given data. It is a matter of personal opinion and values, rather than something that can be objectively measured or proven.

D. All females are taller than males at age 12.

This statement can be tested using the given data. By looking at the average heights of females and males at age 12, we can determine whether females are, on average, taller than males at that specific age.

what is Monosaccharide?

Answers

Answer:

A Monosaccharide is just the simplest form of sugar. It's general term applied to a sugar that cannot be broken down into anything 'simpler'. A great example of this is glucose. Glucose cannot be hydrolized to form anything else, but there are more complex forms of glucose like glycogen. Glycogen is basically a bunch of glucose molecules bonded together and used as "stored glucose", but glycogen can be hydrolized to form individual glucose molecules (monosaccharides).

Monosaccharides, also called simple sugars, are the simplest form of sugar and the most basic units of carbohydrates. The general formula is C ₙH ₂ₙO ₙ, or [Cnn] or { CH2O}n albeit not all molecules fitting this formula are carbohydrates. They are usually colorless, water-soluble, and crystalline solids.
