The diagram below represents the populations in two different ecosystems.

Question

#1 #2


Which of the following is true?
A.
Ecosystem 2 is more stable than ecosystem 1 because it has less biodiversity.
B.
Ecosystem 1 is more stable than ecosystem 2 because it has more biodiversity.
C.
Ecosystem 1 is more stable than ecosystem 2 because it has less biodiversity.
D.
Ecosystem 2 is more stable than ecosystem 1 because it has more biodiversity.

Answer 1

To determine which statement is true regarding the stability of the ecosystems based on their biodiversity, we can consider the general principles of ecology.

Biodiversity is often linked to ecosystem stability. A higher biodiversity usually contributes to greater stability because it creates more complex interactions among species, enhances resilience to environmental changes, and allows for better resource use.

Based on this understanding, the correct statement is:

B. Ecosystem 1 is more stable than ecosystem 2 because it has more biodiversity.

If Ecosystem 1 has more biodiversity compared to Ecosystem 2, it is generally more stable. Thus, option B is the accurate choice.
