It is a 5 mark question please give good answer...I'll mark brainliest..​

Answer 1

biological magnification happens when there is an increase in the number of chemicals and toxins that accumulate through the trophic levels of a food chain. Chemical substances from agriculture and industries tend to be released into the environment, making their way toward food chains and food webs.

Normally within food chains and food webs, biological magnification doesn’t directly affect living organisms. However, exposure to these harmful chemicals may cause some long-term and irreversible side effects

EXAMPLE. For crops and plants (producers), to eradicate the pests, pesticides, and fertilizers are being used. When animals (herbivores) such as deer, goats, & cows graze these plants, the toxic substances get into these animal systems.
