Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organism ends the food chain? Hint:It recycles dead matter/material back into the soil.
A
sun
B
producer/plant
C
consumer
D
decomposer
Explanation: 

Detailed explanation-1: -Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.

Detailed explanation-2: -Detritivores and decomposers are the final part of food chains. Detritivores are organisms that eat nonliving plant and animal remains. For example, scavengers such as vultures eat dead animals.

Detailed explanation-3: -Every part of an ecosystem is vital to its survival – from the green plants to furry animals and microscopic bacteria. The group of organisms called decomposers forms the final link in the food chain. They break down dead animals and plants and return vital nutrients to the soil.

Detailed explanation-4: -Decomposers (fungi, bacteria, invertebrates such as worms and insects) have the ability to break down dead organisms into smaller particles and create new compounds. We use decomposers to restore the natural nutrient cycle through controlled composting. Decomposers are the link that keeps the circle of life in motion.

Detailed explanation-5: -The organisms that carry out the process of decay or breakdown of the dead organism are known as decomposers and the process of breaking down complex organic matter into its simpler form is referred to as decomposition.
