What would happen in the environment if a toxin eliminated large numbers of denitrifying bacteria in the soil? Large amounts of nitrates would accumulate within the soil. The amount of nitrogen fixation in the nodules would decrease. O Large amounts of nitrites would be lost from the soil. O The conversion of atmospheric nitrogen to ammonia would increase.

Figure 22.19 Which of the following statements about the nitrogen cycle is false? Nitrogen fixing bacteria exist on the root nodules of legumes and in the soil. Denitrifying bacteria convert nitrates (NO3 ) into nitrogen gas (N2). Ammonification is the process by which ammonium ion (NH4+) is released from decomposing organic compounds. Nitrification is the process by which nitrites (NO2-) are converted to ammonium ion (NH4+).
. Describe in basic terms the process of biological nitrogen fixation,why it is important, and how oxygen interferes with this process.
* © 54% a hcisd.instructure.com accumulates in soil and water. Some forms of DDT decompose slowly. Worms, grasses, algae, and fish accumulate DDT. Apex predators, such as eagles, had high amounts of DDT in their bodies, accumulated from the fish and small mammals they prey on. Birds with high amounts of DDT in their bodies lay eggs with extremely thin shells. These shells would often break before the baby birds were ready to hatch. DDT was a major reason for the decline of the bald eagle, an apex predator that feeds primarily on fish and small rodents. Today, the use of DDT has been restricted. The food webs of which it is a part have recovered in most parts of the country. Answer the following questions based on the reading in paragraph format. 1. Describe what DDT is and how does it impact the food web. 2. Do you think humans health can be affected by hazardous bioaccumulates in an ecosystem? Make sure you explain using a statement from the reading. 3. Do you think DDT is the only…

Species that fit as remediatiors. EARTHWORN They promote bioremediation of organic contaminants by their physical , chemical and biological actions.They aerate the soil by their burrowing nature and increases the fertility and nutrient content in the soil. They can be used in vermicomposting of waste materials and the prepared compost can be used in growing agricultural produce thereby reducing the use of heavy toxic chemicals in the soil. QUESTION: Design a concept of bioremediation related to earthworm
