Question

Accumulated heavy metals cannot be metabolised by organisms.

• A. True
• B. False

Answer 1

The correct option is A True

Heavy metals like cadmium, arsenic and lead released into the soil from fertilisers are toxic to the environment. When these elements enter the food chain in aquatic or terrestrial ecosystems, there occurs an increase in their concentration at each successive trophic level, which is a process known as biomagnification.
