Pesticides and birds. Put in the evidence in the correct order to explain what happened to the birds?

1) DDT can alter behaviour of birds, sometimes preventing them building proper nests

2) The population of many wild birds have decreased over the last 30 years

3) In large amounts DDT can be poisonous to birds

4) Any perticide in the plankton gats into the fish

5) Fish eat many plankton organisms

6) Many wild birds, such as osprey and heron, eat fish

7) Some of the pesticides is washed into lakes and rivers

8) DDt is absorbed by tiny organisms in the water called plankton.

9) DDT may cause wild birds to become infertile.

10) A pesticide (DDT) is sprayed over fields of crops to kill insects pests.

11) DDT can cause birds to lay eggs with thinner shells. As a result more eggs are likely to be broken.

12) DDT builds up inside fish.
