Question

Explain why there is a need for a variety of animals and plants in a forest. [4 marks]

Answer 1

• Variety of animals and plants living in forests build a rich biodiversity. Different animals and plants play a different role in forest. [1 mark]
• For example, herbivores eat green plants and provide food for the carnivores. Similarly, carnivores eat the herbivores and check their population. This biodiversity makes forests more productive and stable. [1 mark]
• If there is no grass, all herbivores would die. If there are no carnivores, the herbivores would eat up all the plants and there will be a shortage of food. If there are no decomposers, the dead remains of plants and animals would pollute the environment. [1 mark]
• Due to such a biodiversity, a balance in nature is maintained. [1 mark]
