Solution

Green plant

Explanation:

Green plants are the primary producers in an ecosystem, forming the base of the food chain by converting solar energy into chemical energy through photosynthesis. If removed, there would be no energy input into the system, leading to the collapse of the entire community because consumers and decomposers depend on plants, directly or indirectly, for food and energy. Thus, removing green plants has the most serious and lasting effect on others.
