Whether all organism are similar? Justify your answer?

Ans: No, all organisms are not similar.

• Organisms on the earth exhibit great diversity.

• Organisms are grouped as microbes, plants (autotrophs), animals (heterotrophs) and decomposers.

• Different microbes and decomposers have various shapes and sizes.

• Plants can be further classified on their shape, size, structure, mode of reproduction, etc. Plants also differ greatly based on the locations in which they are found. e.g. Snowy, desert, forest, aquatic, etc.

• Even animals show a high degree of variation. They are classified as unicellular, multicellular, invertebrates, vertebrates, etc. Also, based on the environment in which they live, they are classified as terrestrial, aerial, aquatic, and amphibians.

Whether all organisms prepare their own food? 

No, all organisms do not prepare their own food. Organisms that prepare their own food are known as autotrophs (e.g. Green plants, certain microbes). These organisms prepare their own food in the presence of sunlight, water, and carbon dioxide.
