Q.3 - Biology

Question

Which of the following statements is false? 

a. Tissues exist within organs which exist within organ systems. 

b. Communities exist within populations which exist within ecosystems. 

c. Organelles exist within cells which exist within tissues. 

d. Communities exist within ecosystems which exist in the biosphere. 

Step-by-Step Solution

Answer

The correct answer is (b) Communities exist within populations which exist within ecosystems. 

Step1. Introduction

• Organelles are small structures that exist within cells. Examples of organelles include mitochondria and chloroplasts.
• All living things are made of cells. The cell itself is the smallest fundamental unit of structure and function in living organisms. 
• In larger organisms, cells combine to make tissues, which are groups of similar cells carrying out similar or related functions.
•  Organs are collections of tissues grouped together performing a common function.
•  A community is the sum of populations inhabiting a particular area. 
• An ecosystem consists of all the living things in a particular area together with the abiotic, nonliving parts of that environment such as nitrogen in the soil or rain water.  

Step2. Explanation for correct answer

b. Communities exist within populations which exist within ecosystems. 

• A community is the sum of populations inhabiting a particular area. For instance, all of the trees, flowers, insects, and other populations in a forest form the forest’s community .
• The given statement (b) is false. Hence, this (b) is the correct option.

Step3. Explanation for incorrect option

a. Tissues exist within organs which exist within organ systems. 

• Cells combine to make tissues, which are groups of similar cells carrying out similar or related functions. Organs are collections of tissues grouped together performing a common function. 

c. Organelles exist within cells which exist within tissues. 

• Organelles are small structures that exist within cells. And cells combine to make tissues. 

d. Communities exist within ecosystems which exist in the biosphere. 

• A community is the sum of populations inhabiting a particular area and the biosphere is the collection of all ecosystems .
