Some insects such as bumblebees, moths, butterflies, wasps and beetles hatch from eggs into larvae, form into pupa and finally develop into adult insects.

Organic farming is becoming very popular and organic food can now be found in most supermarkets due to public demand. Organic farmers only use natural fertilisers such as horse manure and compost made from rotted plants, to grow their crops. These provide nutrition for the soil and helps the plants to grow, but they do not contain chemicals such as herbicides, pesticides and fungicides which can pollute rivers and soil.
