Which is not an example of a single species on Earth?

A.All the bacteria in a pond
B. All the water lilies in a pond
C. All the bullfrogs in a pond
D. All the small mouth bass in a pond

Answer 1

A

Step-by-step explanation:

B, C, and D are examples of single species on Earth, while A is not.

Option B refers to all the water lilies in a pond, which is a single species of plant.

Option C refers to all the bullfrogs in a pond, which is a single species of amphibian.

Option D refers to all the small mouth bass in a pond, which is a single species of fish.

Option A, however, refers to all the bacteria in a pond. Bacteria are a diverse group of microorganisms, and a pond can contain many different species of bacteria, making option A not an example of a single species on Earth.Therefore, the correct answer is A.
