It is more difficult for roots to absorb water if the soil is hard and compacted.
In a poorly lit room a plant stem will bend towards a window to increase the rate of photosynthesis.

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 or organ poisoning effects).

Which of the following is most likely NOT to be true? [9d-22]

The DDT concentration in the organism decreases up the food chain (=>).
The DDT molecules are chemically very stable.
The insects ingest the DDT if they eat any part of the plants or even absorb it by contact.
The blue-tits ingest the DDT when they eat the insects.
The DDT is not easily excreted by the animals in the food chain.

A series of experiments was done to see the effects of various minerals on the quality of plant growth. More importantly, these experiments can show the effects of a soil that is lacking (deficient) in any essential mineral.

(expt.) MINERALS added to the soil	EFFECTS of the mineral on plant growth
(1) nitrate, phosphate, potassium, trace metals (Cu, Fe, Mg, Mn, Zn)	healthy roots, strong stem, healthy green leaves, well developed flowers
(2) nitrate, phosphate, trace metals (Cu, Fe, Mg, Mn, Zn)	healthy roots, strong stem, older green leaves yellow with black spots, poorly developed flowers
(3) nitrate, potassium, trace metals (Cu, Fe, Mg, Mn, Zn)	poorly developed roots, strong stem, leaves turn very dark green then purple, poor quality flower blooms
(4) nitrate, phosphate, potassium	healthy roots, strong stem, yellowish leaves, well developed flowers
(5) phosphate, potassium, trace metals (Cu, Fe, Mg, Mn, Zn)	healthy roots, thin weak stem, smaller yellow leaves, well developed flowers

From the experiment data, which mineral deficiency causes poor root growth? [9d-27]

lack of phosphate
lack of nitrate
lack of nitrate or phosphate or potassium or trace metals
lack of potassium or phosphate
