(1) Red worms
(2) a. Plastic, Glass b. Plants, animal waste
(3) Plastic and Metal waste
(4) Gizzard
(5) Plastic and Glass.
(6) Vermicompost
(7) Biodegradable

(11) Composting.
(12) a. redworms b. garbage.
Short Answer Type Questions:

(26) Waste materials especially household wastes, are called garbage.
Explain with example:
The peels of fruits and vegetables left over cooked food and fallen leaves of potted plants are thrown away as garbage. The packing material are useless and thrown away as garbage. Used paper are garbage etc.
If garbage is not removed from or homes and surroundings regularly our homes and surroundings will become dirty. Some of the garbage will rot giving off bad smell.

The method of making compost from kitchen wastes by using redworms is called vermicomposting.
Vermicomposting is better as it is very high quality of manure.
(28) Recycling means that we should collect and separate the used and discarded items made of paper, plastic, glass and metals and send them to the respective industries for making fresh paper, plastic, glass and metal object.
Recycle Paper at Home or School:
(1) Take the paper and torn up into small pieces and placed it in a tub. Then give some water and submerged it for some days.
(2) Take a fine wire mesh fixed to a frame. Keep this wire mesh on a table. Now take the thick paste of paper from the tub and spread it on the wire mesh. Pat it gently to obtain uniformly thick layer of paper paste. Wait till all the water from paper paste drains off. A sheet of old cloth or a newspaper can also be used to suck up extra water present in the layer of paper sheet.
(3) Remove the layer of paper paste from the wire mesh carefully and spread it on a sheet of newspaper kept it in the sunshine. Keep the corners of newspaper pressed by putting some weights so that they do not curl up. The heat of sunlight remove all water lest in the layer of paper paste and make it completely dry. Now it’s ready as new paper.

Most of the solid garbage from a city which can not be disposed by other method is got rid of by dumping in landfills.
(30) We use different types of plastics in our daily life as polythene bags, water bottle, water tanks, pipes, pens, combs, electric wires, radio, television, refrigerator, cars, buses, scooters, trains etc.
List of things made of plastic which are used by us at longer time that is very difficult to imagine our life without plastic. In that case plastics are a boon whereas some of plastic which are used for some of time and thrown it, therefore its not rotted by soil in that case plastics are curse for us.

(c) We should use paper wherever possible to reduce the use of polythene.
(4) we should give old plastic toys to others who can use them etc.
