an organism that breaks down organic matter in simpler materials (like carbon dioxide) is called a decomposer. absorb nutrients from living things or the organic matter they leave behind. they do not need to kill to get their food.

Answer 1

You are describing decomposers, which play a crucial role in ecosystems. These organisms, which include fungi, bacteria, and some insects, break down dead organic matter and waste products, returning essential nutrients to the soil and making them available for plants and other organisms. Decomposers help recycle nutrients and maintain the balance of ecosystems. They contribute to processes like composting and nutrient cycling, ensuring that ecosystems remain healthy and productive. By absorbing nutrients from the organic matter they decompose, they facilitate the flow of energy through food webs without needing to kill living organisms. This makes them vital for environmental sustainability.
