(d) Drains get blocked by __________ and __________.
Ans.(a) pollutants (b) sewage (c) sludge (d) (d) chemicals, kitchen waste

2. What is sewage? Explain why it is harmful to discharge untreated sewage into rivers or seas.

Wastewater released by houses is called sewage. Untreated sewage should not be discharged untreated into the sea because sewage consists of pollutants and harmful microorganisms which will contaminate water causing disease in people using contaminated water.

3. Why should oils and fats be not released in the drain? Explain.

Oils and fats should not be released in the drain because drains get blocked by cooking oil and fats.

Q.4. Describe the steps involved in getting clarified water from wastewater.
Ans. Following steps are involved in the purification of water:
(i) Firstly all the physical impurities like stones, plastic bags, cans etc. are to be removed. It is done by passing the water through bar screens.
(ii) Then water is taken to grit and sand removal tank where impurities are removed by sedimentation.
(iii) Solid impurities and feaces etc. are collected from bottom of water. These impurities collected are called sludge.
(iv) Clarified water is cleaned of other impurities by aerator. All disease causing bacteria are removed by chlorination.

Q.5. What is sludge? Explain how it is treated.
Ans. Sludge is the collected solid waste from the wastewater during the treatment in water treatment plant. Sludge is decomposed in a separate tank by the anaerobic bacteria. Activated sludge is used as manure.

Q.6. Untreated human excreta is a health hazard. Explain.
Ans. Untreated human excreta can cause a lot of health related problems. It pollutes water, air and soil. The polluted water contain disease causing bacteria which can spread epidemics like cholera, meningitis etc.

Q.7. Name two chemicals used to disinfect water.
Ans. Chlorine and ozone

Q.8. Explain the Junction of bar screens in a wastewater treatment plant.
Ans. Bar screens clear the wastewater of all the physical impurities. Large size waste like napkins, plastics, cans etc. are removed from the wastewater through the bar screens.

Q.9. Explain the relationship between sanitation and disease.
Ans. Sanitation and disease are related to each other. Sanitation involves proper disposal of sewage and refuse from hou&e and public places. If sanitation is there, no disease will occur, but if sanitation is not there various types of disease will occur and spread. So sanitation should be kept to avoid disease.

SOLUTIONS of Chapter 17 Forests: Our lifeline, CLASS 7

 1. Explain how animals dwelling in the forest help it grow and regenerate.

Animals dwelling in the forest help it grow and regenerate in the following ways

• Animals help in dispersing plant seeds.
• Decaying animal dung provides nutrients for plants to grow
• Microorganisms convert the dead plants and animals to humus

2. Explain how forests prevent floods.Solution:

Plants in the forests will not allow the rainwater to fall directly on earth and these plants also hold water which helps in preventing floods.

3. What are decomposers? Name any two of them. What do they do in the forest?

The micro-organisms which convert the dead plants and animals to humus are known as decomposers. Example: bacteria and Fungi. They help in recycling of nutrients by decomposing dead plants and animals.

4. Explain the role of forest in maintaining the balance between oxygen and carbon dioxide in the atmosphere.

Plants in the forests consume carbon dioxide and releases oxygen by photosynthesis process. This helps in balancing oxygen and carbon dioxide in the atmosphere.

5. Explain why there is no waste in a forest.

There is no waste in a forest because waste created is bio-degradable, which gets converted to humus by the action of microorganism.

6. List five products we get from forests?

i) Medicines

ii) Spices

iii) Wood

iv) Paper

v) Gum

7. Fill in the blanks:

(a) The insects, butterflies, honeybees, and birds help flowering plants in pollination.

(b) A forest is a purifier of air and water .

(c) Herbs form the lowest layer in the forest.

(d) The decaying leaves and animal droppings in a forest enrich the soil.

8. Why should we worry about the conditions and issues related to forests far from us?

We should worry about the forest for the following reasons.

• A decrease in forest results in an increase in Carbon dioxide content in the atmosphere this results in global warming.
• Depletion of forests results in soil erosion
• Decrease in forest adversely affect the lives of animals living in the forest.
• Absence of forests leads to flooding more often.
• Due to the reduction of forest land will turn barren which is called desertification.

9. Explain why there is a need of variety of animals and plants in a forest.

Variety of plants and animals in the forests helps plants to regenerate and grow. More excellent range of plants supports herbivores, which in turn serve as food for carnivores. Decomposers turn dead animals and plants into humus; thereby maintain nutrient recycling. This wide variety makes forest a dynamic living entity.
