A
Only plants
B
Only aquatic animals
C
Only decomposers
D

Verified step by step guidance1
Understand the role of water in an ecosystem: Water is a fundamental resource that supports all life forms, including plants, animals, and microorganisms. It is essential for processes like photosynthesis, cellular respiration, and maintaining homeostasis.
Analyze the impact on plants: Plants rely on water for photosynthesis, which is the process of converting light energy into chemical energy. A decrease in water supply can limit their ability to produce food and grow.
Consider aquatic animals: Aquatic animals depend on water for their habitat and survival. A reduced water supply can lead to habitat loss, decreased oxygen levels, and challenges in maintaining their physiological processes.
Evaluate decomposers: Decomposers, such as fungi and bacteria, require water to break down organic matter effectively. A lack of water can slow decomposition and nutrient cycling in the ecosystem.
Conclude that all organisms are affected: Since water is vital for the survival and functioning of plants, animals, and microorganisms, a decreased supply of water impacts all organisms in the ecosystem, not just specific groups.
