Q.1 Estimates of the total number of species on Earth range from as low as 3 to 5 million to around _____ million.
This wide range of organisms is described as diversity of organisms.
Q.2 Try to match the following organisms with the place where they live.
1. Shrimp A. rocky store
2. Mushroom B. desert
3. Penguin C. polar region
4. Camel D. woodland
5. Hermit crab E. river
The place or natural environment where each type of organism lives is called its habitat.
To help identify and study organisms, biologists sort/classify them into groups
Sorting organisms into groups is called classification.
Q.3 What is the main difference between them?
(Hints: consider their ways of obtaining food)
Animals are further classified, according to other features, into 2 groups:
vertebrates (animals with backbones)
invertebrates (animals without backbones)
1. Point out that there is a large variety of living things.
2. Classify animals into vertebrates and invertebrates.
3. Classify vertebrates into fishes, amphibians, reptiles, birds and mammals.
4. Classify plants into flowering and non-flowering plants using external features.
5. Classify non-flowering plants into algae, fungi, mosses, ferns and gymnosperms.
6. Use an identification key.
