Prof Ahmad replied that they feedupon the dead plant and animal tissues and convert them into a dark coloredsubstance called humus.The micro-organisms which convertthe dead plants and animals to humusare known as decomposers. Thesemicro-organisms play an important rolein the forest. Soon, Paheli removed somedead leaves and discovered under thema layer of humus on forest floor. Thepresence of humus ensures that thenutrients of the dead plants andanimals are released into the soil. Fromthere, these nutrients are again absorbedby the roots of the living plants. “What happens if an animal dies in the forest?”Sheila asked.

Animals, and explained the differencebetween various types of droppings.Prof Ahmad informed them that theforest officers could recognize thepresence of some animals in the forestby their droppings and footprints.Boojho called every one and showedthem a large, decaying heap of animaldropping. Several beetles and grubswere feeding on the heap and a bunchof seedlings was sprouting.

 “Theseseedlings are of the herbs and shrubs the animals also disperse the seeds ofcertain plants and help the forest to growand regenerate. The decaying animaldung also provides nutrients to theseedlings to grow”, said Prof Ahmad.After listening to this, Boojho notedin his notebook, “By harboring greatervariety of plants, the forest providesgreater opportunities for food andhabitat for the herbivores. Largernumber of herbivores means increasedavailability of food for a variety of carnivores. The wide variety of animalshelps the forest to regenerate and grow.Decomposers help in maintaining thesupply of nutrients to the growing plants in the forest. Therefore, the forest is a‘dynamic living entity’ — full of life andvitality.”

Que. 5) What does large number of herbivores means?

Que. 1) (c) Deer

Que. 2) (b) Animals

Que. 3) (a) Nutrients, grow

Que. 4) Answers: Decomposers are the microbes who help in maintaining the supply of nutrients required for the growth of plants.

Que. 5) Answer: Large number of herbivores indicates that there is more availability of food for the carnivores.
