Question

13.
In an ecosystem, the decomposition of organisms takes place by
(1) phagotrophs
(2) reducers
(3) primary consumers
(4) secondary consumers​

Answer 1

In an ecosystem, the decomposition of organisms takes place by reducers

• Reducers are the organisms that convert complex organic matter into simpler chemicals in order to produce energy in an environment.
• They are essential to the breakdown of organic materials and nutrient cycling in an ecosystem.
• Numerous creatures, including bacteria, fungi, and some invertebrates like worms and snails, are reducers.
• These creatures decompose waste materials and dead plant and animal matter into simpler compounds that can be utilised by other organisms in the ecosystem.
• Whereas, phagotroph is species that get energy from eating other organisms. The creatures that consume producers are primary consumers and the organisms that consume primary consumers are secondary consumers.

Answer 2

Answer:

ans is reducers.

Explanation:

When organisms die, they leave behind energy and matter in their remains. Decomposers break down the remains and other wastes and release simple inorganic molecules back to the environment. Producers can then use the molecules to make new organic compounds. The stability of decomposers is essential to every ecosystem.

.Reducers are an important part of the ecosystem because they help with nutrient cycling, break down dead organic matter (animal and litter), and are therefore called natural scavengers or simply decomposers. For example, fungi and some types of bacteria.
