How Does Biomagnification Occur? Explain 2 reasons

Biomagnification is the process of building up harmful substances in the food chain. This process occurs when organisms eat other organisms that contain toxic substances or substances that cannot be broken down by the body. As a result, organisms that eat these organisms will also experience a buildup of these dangerous substances. This process can occur in all types of living creatures, including humans.

Causes of Biomagnification

There are several causes of biomagnification, including:

1. Bioaccumulation

Bioaccumulation is the process of accumulation of harmful substances in the body of living organisms. These dangerous substances can come from the surrounding environment, such as water and soil contaminated by dangerous chemicals. Organisms that are exposed to these dangerous substances will absorb these substances through food or air and store them in their bodies.

An example of bioaccumulation is the buildup of mercury in fish. Mercury is a dangerous substance that can cause damage to the human nervous system. Fish that live in waters contaminated with mercury will absorb this substance through the food and water they consume. As a result, mercury levels in the fish’s body will continue to increase as the age and size of the fish increases.

2. Biomagnification

Biomagnification is the process of building up harmful substances in the food chain. These dangerous substances can originate from organisms lower in the food chain and continue to accumulate in organisms higher in the food chain. Organisms lower in the food chain will absorb these dangerous substances through the surrounding environment, such as water and soil contaminated with dangerous chemicals. Then, organisms higher in the food chain will eat the lower organisms and absorb the dangerous substances contained in the bodies of these organisms.

An example of biomagnification is the buildup of DDT in fish-eating birds. DDT is an insecticide used to kill insects. Fish-eating birds will catch fish contaminated with DDT and store them in their bodies. As a result, DDT levels in the bird’s body will continue to increase as the bird ages and size increases.

Closing

Biomagnification is the process of building up harmful substances in the food chain. This process occurs when organisms eat other organisms that contain toxic substances or substances that cannot be broken down by the body. The causes of biomagnification include bioaccumulation and biomagnification itself. To reduce the risk of biomagnification, efforts are needed to reduce the use of hazardous chemicals and maintain the cleanliness of the surrounding environment.
