An ecosystem is comprised of a group of living organisms (microorganisms, animals, and plants) and non-living organisms (water, air, and mineral soil). The ecosystem does not possess a well-defined physical boundary. Ecologists state the ecosystem in different ways based on its functions, particularly how the nutrients and energy are assimilated and disseminated by the living organisms.

Chapter 18, Problem 1TQ

Summary Introduction

An ecosystem is comprised of a group of living organisms (microorganisms, animals, and plants) and non-living organisms (water, air, and mineral soil). The ecosystem does not possess a well-defined physical boundary. Ecologists state the ecosystem in different ways based on its functions, particularly how the nutrients and energy are assimilated and disseminated by the living organisms.

Expert Solution & Answer

Answer to Problem 1TQ

Nutrients continuously traveled between the living things (biotic) and non-living things (abiotic). The movement of nutrients among various organisms as well as the physical environment is known as nutrient cycling. Therefore, option (a) is correct.

Explanation of Solution

Justify reasons for the correct statement:

Chemicals essential for effective growth and survival of the organisms in an ecosystem are referred as nutrients. A nutrient cycle is the continuous movement of nutrients from the physical surroundings into a living organism. Later, the nutrient is reprocessed back into the physical environment. Therefore, the movement of nutrients between physical environment and the living organism is termed as nutrient cycling.

Option (a) is given as “nutrient cycling”.

Hence, option (a) is correct.

Justify reasons for the incorrect statements:

Option (b) is given as “ecosystem services”.

Ecosystem services are categorized into four types. They are provisioning (water and food production), regulating (climate and disease control), cultural (recreational and health benefits), and supporting (oxygen production and nutrient cycles). Therefore, it is not directly associated only with the nutrient cycle. Hence, it is a wrong answer.

Option (c) is given as “net primary productivity”.

The rate at which plants generate net essential chemical energy in an ecosystem is referred to as a net primary productivity. Therefore, it is not related to the nutrient cycle. Hence, it is a wrong answer.

Option (d) is given as “decomposition”.

It is the process of decay or rotting, which is achieved by the breakdown of complex organic compounds into simpler organic forms. Hence, it is a wrong answer.

Hence, options (b), (c), and (d) are incorrect.

Conclusion

The movement of nutrients between organism and the physical environment is termed as nutrient cycling.

2. Drug quantification from plasma is commonly performed by using techniques such as HPLC or LC/MS. However, these methods do have limitations, and investigators may choose to use a radiolabeled analog of a drug instead. Radioligands are molecules that contain radioactive isotopes, commonly 3H or 14C. This technique allows investigators to quantify drug concentration from radiation measurements. The following measurements were made in 250 g rats following oral administration of 18.2 µCi of a 14C-labeled drug of interest: Time (min) Plasma Radiation Levels (µCi/L) 0 0.0 2 9.7 4 19.2 7 25.3 9 37.8 12 39.6 14 45.8 17 48.8 20 52.0 25 56.4 30 59.2 35 60.1 40 61.1 45 62.1 50 62.8 60 63.1 70 62.1 80 60.1 90 57.3 100 55.5 110 53.7 120 52.2 150 48.0 180 45.0 240 39.0 Note that a µCi is a measure of the amount of radioactivity and hence is a measure of the amount of drug present.
