Question

A forest ecosystem is a major ecologic unit. The forest ecosystem is associated with land mass covered in trees. The forest ecosystem includes biotic (living) interactions between plants, animals and micro-organisms, and abiotic (nonliving) physical and chemical interactions. Identify a key abiotic component of a forest ecosystem.

Option 1: birds
Option 2: water
Option 3: trees
Option 4: algae

Answer 1

In a forest ecosystem, water is a key abiotic component, essential for life and involved in various ecological processes. Living entities like birds, trees, and algae are considered biotic components.

Step-by-step explanation:

An ecosystem is a community of living organisms (biotic components) and their interactions with the abiotic (non-living) environment. In a forest ecosystem, one of the key abiotic components is water. Water is crucial for the survival of plants, animals, and micro-organisms; it is involved in nutrient cycles and helps regulate the ecosystem's climate. Options such as birds, trees, and algae are considered biotic components as they are all living organisms.
