Q.14

Question

Which of the following sequences represents the hierarchy of biological organization from the most inclusive to the least complex level? 

a. organelle, tissue, biosphere, ecosystem, population 

b. organ, organism, tissue, organelle, molecule 

c. organism, community, biosphere, molecule, tissue, organ 

d. biosphere, ecosystem, community, population, organism 

Step-by-Step Solution

Verified
Answer

The correct answer is (d) biosphere, ecosystem, community, population, organism 

1Step1. Introduction

The highest level of organization for living things is the biosphere; it encompasses all other levels. 

The biological levels of organization of living things arranged from the simplest to most complex are: 

                  organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

2Step2. Explanation for correct answer

d. biosphere, ecosystem, community, population, organism 

The biological organization is composed of the organism, population, community, ecosystem, and biosphere. 

Organism is considered as the least complex as it is the start of the organization which pertains to an individual. The organization becomes complex which makes it more complicated.

From the given categories in a biological organization, the hierarchy from the most inclusive to the least complex is:

  • Biosphere
  • Ecosystem
  • Community
  • Population
  • Organism
3Step3. Explanation for wrong answer

a. organelle, tissue, biosphere, ecosystem, population 

  • The highest level of organization for living things is the biosphere; it encompasses all other levels. Hence this option is not correct.

b. organ, organism, tissue, organelle, molecule 

  • The highest level of organization for living things is the biosphere; it encompasses all other levels. Hence this option is not correct.

c. organism, community, biosphere, molecule, tissue, organ 

  • The highest level of organization for living things is the biosphere; it encompasses all other levels. Hence this option is not correct.
