Solution

Explanation:1 Mark each.
(a) Wild animals
The habitat of wild animals is drastically reduced. This creates a scarcity of food and dwelling places for wild animals and ultimately leads to their extinction.

(b) Environment
Green plants prepare their food and all other organisms depend on their food on green plants. So, deforestation disturbs the food chain. Green plants also help in precipitation and deforestation reduces the amount of precipitation. Green plants take in carbon dioxide and release oxygen during photosynthesis and thus maintain the balance of carbon dioxide and oxygen in the environment. Deforestation disturbs this balance.

(c) Villages (Rural areas)
Deforestation leads to soil erosion and results in flash floods. This hampers agricultural activities and thus disturbs the people in rural areas.

(d) Cities (Urban areas)
Cities depend on rural areas and forests for many items; like food and timber. Deforestation can reduce this supply of necessary items to people in urban areas.

(e) Earth
The whole earth is full of various ecosystems which together make the biosphere. Deforestation disturbs the balance in the biosphere. It disturbs climatic patterns.
