NIOS Class 10 Science Activity 19.3 Classification of Living Organisms

In this activity, we will prepare a flow chart for diversity in reproduction and respiration according to the given flow chart of diversity in feeding.

Classification of Living Organisms Activity Solution

This activity is based on the NIOS Class 10 science and technology (212) Chapter 19- Classification of Living Organisms Module 5- The Living World

Aim

To prepare a flow chart showing the diversity in reproduction and respiration among living organisms.

Materials Required

   1. White sheet

   2. Pencil, colours

   3. Flow chart boxes

   4. Glue

Procedure

We will go through the flow chart on diversity in feeding different living organisms.

Now we draw two separate flow charts on

(i)         Diversity in reproduction

(ii)      Diversity in respiration

We will use the words given in the brackets and arrange the terms from the main heading, and divide them into subgroups.

Now we decorate and colour the chart to make the more readable.

Observation and Explanation

Living organisms show diversity in reproduction. They use different reproduction methods; some use asexual reproduction,  e.g. amoeba, hydra, and some use sexual reproduction, e.g, human and other mammals.

The living organisms also show diversity in respiration. Some use oxygen from air or water; this is called aerobic respiration. Some do not require oxygen; this is called anaerobic respiration.

Organisms live in a large region called the biosphere. Different ecosystems like ponds, oceans, mountains, rivers, and deserts support different species.

Conclusion

This activity shows that the diversity in reproduction and respiration in living organisms depends on their structure, habitat and environment.
