The answers are:

3) paper (B)

4) trees take in carbon dioxide exhaled by humans and give off oxygen is inhaled by man (B)

5) Trees gives a feeling of freshness and coolness. (C)

Explanation:

Trees are essential in the environment and nature, as they play vital roles, but due to industrialization, the felling of trees has increased in recent times, hence the cry by environmental activists on the stopping of deforestation.

3) Paper is made from pulp, which is made from wood fiber after tree is felled, hence students who use paper benefit directly from the fiber of trees.

4) ecological balance is the maintenance of homeostasis in the environment between the living and non-living systems. Trees use carbon dioxide exhaled by humans for photosynthesis hence mopping up CO₂ from the atmosphere and in turn giving off oxygen which is inhaled by man, maintaining a CO₂ - O₂ balance.

5) The presence of trees in a place provides freshness and coolness to the atmosphere because the air around is filtered and the trees act as shades from direct sunlight and UV rays.
