Question

1. Distinguish between a. Autotrophs and heterotrophs b. Decomposers and scavengers
​

Answer 1

Answer:

Technically, the definition is that autotrophs obtain carbon from inorganic sources like carbon dioxide (CO2) while heterotrophs get their reduced carbon from other organisms. ... Scavenger and decomposer are two types of organisms that are responsible for the recycling of organic matter.

Answer 2

Answer:

An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals.

A heterotroph is an organism that cannot manufacture its own food by carbon fixation and therefore derives its intake of nutrition from other sources of organic carbon, mainly plant or animal matter.

Decomposers are organisms that break down dead or decaying organisms and in doing so, carry out the natural process of decomposition.

Scavengers are animals that consume dead organisms that have died from causes other than predation.
