for unicellular organisms that dominated earth up to the Precambrian
times.
The correct answer for question number 2 is C - the
greenhouse effect is related to the phenomenon of an increase in average
surface temperature known as global warming.
The correct
answer for question number 3 is D - the colourless and odourless gas
that is produced by the radioactive decay of Uranium-238 and is considered
to be a cancer-causing agent is Radon.

<h3>What are Decomposers?</h3>
Decomposers are organisms present at the end of the food chain. These are organisms responsible for acting on the dead and decaying organic matter left out by other organisms and converting them into inorganic matter or simply into nutrient-rich soil.
<h3>Role of Decomposers</h3>
They help in making nutrients available to the primary producers. In a food chain or food web, they are usually present at the last and complete the life cycle. Decomposers in the case of the terrestrial ecosystems are usually microscopic organisms like <u>fungi, bacteria, or invertebrates like earthworms and millipedes</u> which are responsible for decomposing dead and decaying material.
So, in this particular terrestrial ecosystem, the species at the end of the food web (E) is most likely the decomposer as it ends the food web.
