The highest trophic level in an ecosystem is obtained by:

Detailed Solution:

The correct answer is “Carnivores”.

In an ecosystem, the highest trophic level is obtained by: (2) Carnivores

Trophic level refers to the position an organism occupies in the food chain based on its feeding habits. Carnivores are organisms that primarily feed on other animals. They occupy a higher trophic level in the food chain compared to herbivores (which feed on plants) and omnivores (which feed on both plants and animals).

Decomposers, while important in nutrient cycling, do not fit into traditional trophic levels as they break down organic matter rather than directly consuming other organisms.
