Question

Give three examples of the range of variations you see in life-forms around you.

Answer 1

Range of variations refers to the differences observed in life-forms around us. It could be related to physical attributes such as size, colour, shape, etc., or it could also be related to attributes such as life span as well.

Complete answer:
Variations in life-forms around us and that could be based on various attributes, such as size, shape, colour, and lifespan.
• Every species of life-form around us has unique attributes that differ to other species.
• The three examples of range of variations you see in life-forms around us are:

Variations in lifespan
Lifespan can be defined as the length of time for which an organism functions and survives. Animals like turtles can easily live up to 80 years and sometimes up to 100 years, while insects such as fruit flies (Drosophila melanogaster) live only for a few hours.

Variations in size
Size here refers to the size of the organism. Bacteria and other microorganisms are so small that a microscope is required to see them, while mammals such as the Blue Whale or Banyan trees are very large in size.

Variations in colour
Colour here refers to the presence and intensity of colours on an organism. Life-forms range from colourless worms such as roundworms to birds like Macaws which have multiple coloured feathers.

Note: Range of variations in life could also be described by the habitat certain organisms live in. For example, parasites survive inside the body of another living organism while penguins and polar bears survive in extremely cold habitats.
Another way to describe a range of variations could be with movement. For example, most plants do not move from their location of germination while organisms like birds migrate great distances every year.
