The use of pesticides like DDT to protect crops (grain, fruit etc.) from insect damage is strictly controlled. Chemicals like DDT tend to be insoluble in water but soluble in fatty or oily materials. Some countries have banned their use because of harmful effects on the environment as the pesticides become part of food chains. In the food chain illustrated, the use of 'DDT like insecticides' led to a decline in birds of prey like the kestrel (often due to poor quality egg shells or organ poisoning effects).

Which of the following is most likely NOT to be true? [9d-22]
1. The DDT concentration in the organism decreases up the food chain (=>).
2. The DDT molecules are chemically very stable.
3. The insects ingest the DDT if they eat any part of the plants or even absorb it by contact.
4. The blue-tits ingest the DDT when they eat the insects.
5. The DDT is not easily excreted by the animals in the food chain.
