Question

elaborateddt is an insecticide used by the agriculture industry to kill insects and increase crop yields. it was discovered that wetlands and marsh plants absorbed the poison and it was passed up the food chain where it accumulated in organisms.directions: for more background on ddt and bioaccumulation watch the video, \biomagnification and the trouble with toxins\ found on the previous page. then follow the steps below to complete the activity.the following diagram depicts a single food chain within a wetland system. a nearby farm used ddt on its crops, and some of the chemicals have runoff the farm from irrigation and into the wetland. each individual marsh plant absorbs 1 unit of ddt. based on this and your knowledge of ecology, answer the questions below. use your answers to fill in the units of ddt for each species in the food chain.note: the illustrations are visual examples of the species, and do not indicate the population within the wetland.1. each minnow eats 100 marsh plants in one year. how much ddt builds up in the body of each minnow? write the number in the space provided below for \minnow\.2. a single perch eats 50 minnows in one year. how much ddt accumulates in the body of each perch? write the number in the space provided below for \perch\.3. a red-tailed hawk consumes 20 perch in one year. what amount of the pesticide builds up in each hawk? write the number in the space provided below for
ed-tailed hawk\.marsh | minnow | perch | red-tailed hawk1 unit of ddt | ____ units of ddt | __ units of ddt | ____ units of ddt

Explanation:

Step1: Calculate minnow's DDT

Each minnow eats 100 plants, each with 1 unit DDT.
$100 \times 1 = 100$

Step2: Calculate perch's DDT

Each perch eats 50 minnows, each with 100 units DDT.
$50 \times 100 = 5000$

Step3: Calculate hawk's DDT

Each hawk eats 20 perch, each with 5000 units DDT.
$20 \times 5000 = 100000$

Answer:

Minnow: 100 Units of DDT
Perch: 5000 Units of DDT
Red-Tailed Hawk: 100000 Units of DDT
