Question 9 • Biology

Which is an example of biodiversity contributing to the sustainability of an ecosystem?

Answer
A
A meadow covers a large area of land, providing shelter to many organisms.
B
Many kinds of fruit trees support a variety of birds and other animals in a forest.
C
The ocean can only support organisms that can survive salty conditions.
D
One species of plant has been growing in a field for several years.

Explanation

Biodiversity means having a variety of living species in an ecosystem. Many kinds of fruit trees provide different food and habitats that can support a variety of birds and other animals, helping the ecosystem remain stable. A meadow’s size alone does not show biodiversity, and one plant species growing in a field indicates little variety.
