Why do some woodland plants grow and flower early in the year?
So that they are able to use the sunlight to photosynthesise and grow. Once the trees have their leaves the smaller plants will receive much less light. They will also gave more competition for water&nutrients from the soil as the trees begin to grow

An elephant has a small surface area to volume ratio. How will this affect the elephant in hot climate?
It will transfer energy slowly. This is why elephant have a folded skin which increases the total surface area and its large ears will also transfer energy effectively.

A farmer plants some seeds in rows 10cm apart. The plants grow well. He wonders if he should plant them closer next year. Explain why this might not produce
When the plants are grown closer together there is more competition for light, water and nutrients. This means that individual plants may not grow as well and the overall yield is the same or lower.

Suggest why some animals in a desert spend all day in a burrow and come out at night.
To keep cool/stay out of the sun and to feed. They are also less easily seen by a predator.

Why is it difficult to interpret data about changes in the distribution of animals and plants?
There are so many possible variables. It may be obvious that the climate has got warmer but this might lead to other changes. For example, if a plant flowers earlier in the year the insects which lead on it may not be around to pollinate the flowers.
