Why is only 10% of the energy consumed by an organism available to be transferred to another trophic level?

Answers

Final answer:

Only 10% of the energy consumed by an organism is available to be transferred to another trophic level due to the laws of thermodynamics and the inefficiency of energy transfer.


Explanation:

Only 10% of the energy consumed by an organism is available to be transferred to another trophic level due to the laws of thermodynamics and the inefficiency of energy transfer. This is known as the 10% rule.

The 10% rule states that energy is lost as heat during the process of respiration and metabolic activities, and only a fraction of the remaining energy is converted into biomass that is available as food for the next trophic level.

For example, if a primary producer (such as a plant) has 1,000 units of energy, only 100 units are passed on to the primary consumer (herbivore), and only 10 units are transferred to the secondary consumer (carnivore) in the next trophic level.

Most people feel confident that they could identify a living thing from a nonliving thing, but sometimes it’s not so easy. Scientists have argued for centuries over the basic characteristics that separate life from non-life. Some of these arguments are still unresolved. Despite these arguments, there do seem to be some generally accepted characteristics common to all living things. Anything that possesses all these characteristics of life is known as an organism. 1.The scientific term for a living thing is a(n) _____________________

Answers

Answer:

An Organism

Explanation:

In biology, scientists defined the characteristics which distinguished between a living thing that has life and a non-living thing which do not have the life.

The thing or entity that shows the characteristics of life like made of the cell, reproduce, genetic material and many others are known as an organism.  Thus the biology is the field of study that studies the different types of organisms like bacteria, protists, animals and plants or living things present on this Earth.

Thus, an organism is the correct answer.

How many moles are in 17.13g of MgO

Answers

Answer:

0.4250 mol MgO

General Formulas and Concepts:

Chemistry - Atomic Structure

  • Reading a Periodic Table
  • Using Dimensional Analysis

Explanation:

Step 1: Define

17.13 g MgO

Step 2: Identify Conversions

Molar Mass of Mg - 24.31 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of MgO - 24.31 + 16.00 = 40.31 g/mol

Step 3: Convert

17.13 \ g \ MgO((1 \ mol \ MgO)/(40.31 \ g \ MgO) ) = 0.424957 mol MgO

Step 4: Check

We are given 4 sig figs. Follow sig fig rules and round.

0.424957 mol MgO ≈ 0.4250 mol MgO
