Find two other examples of compounds that biomagnify. explain how each compound and/or toxin enters the biosphere and what impacts it has on living organisms in general and humans in particular.

1. DDT (

) with molecular formula; C14H9Cl5

2. Lead

Explanation:

1. DDT () is an example of compounds that biomagnifies in the biosphere. DDT is used as pesticides. When DDT is sprayed on plants to kill their pests, part of it is accumulated within the plants.

However, when primary consumers feeds on the affected plants, DDT is passed on to them and then to the secondary consumer in that sequence until it get to the top of the trophic level.

Effects of DDT have been seen in many organisms including birds and humans. The effects seen in humans is quite minimal to that of insects and birds. DDT causes lost of many insects and young birds. In humans, it causes vomiting, seizures etc.

2. Lead: it enters the biosphere by absorption and consumption means. Humans through the use of lead paint, smoking of cigarettes, use of cosmetics and combustion of coal accumulates lead in their bodies. Lead can't be synthesize by human, therefore it accumulates and biomagnify within their systems.

The effects of lead in human include; vomiting, stroke and abdominal pains. In tough scenario, it causes immune system deterioration and cardiovascular diseases.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
