D
С
(a) A
(c) C
(b) B
(d) D​

Answer 1

Answer:

The answer is Option B

Diagram A have 1 mammal (cow and rat) + 1 insect total diversity=2

Diagram B have 1 mammal (cow and rat) + 1 insect + 1 bird total diversity=3

Diagram C have 1 mammal (cow) + 1 insect+ 1 bird+ 1 reptile (snake) total=4

Diagram D have 1 mammal (cow and goat)+ 1 insect + 1 Amphibian (frog) total=3

It means in all given Diagrams, Diagram C have more species diversity.

Answer 2

Answer:

The ecological area D shows the maximum diversity.

Explanation:

Biodiversity is the extent of diverse organisms present in a particular ecological area. Biodiversity is different from the amount of each species present. A particular area may have a large number of single species present (for example 1000 number insects). But it is not diverse. If another area has 50 insects, 50 birds, and 50 mammals, then, it is more diverse. The later area is more diverse because there are different types of organisms present in that area. Thus, biodiversity is the count of the number of varieties of organisms and not the number of organisms.

Given,

Area A = Frog, Crow, Myna.

Area B = Crow, Myna, Parrot.

Area C = Lion, Crow, Parrot.

Area D = Lion, Crow, Insects.

So,

Area A has 1 amphibian (frog) + 2 birds (Crow+myna)

Area B has 3 birds (crow, myna, and parrot)

Area C has 1 mammal (lion) + 2 birds (crow+parrot)

Area D has 1 mammal (lion) + 1 bird (crow) + insects.

Since area D has three different phyla, it is most diverse.

So, the correct option is (d) D.
