Bacteria help the nitrogen change between states so it can be used. Bacteria in the soil or bacteria found in nodules of legumes nitrogen is a necessary component of life as plants need it to grow and animals need it to create dna. Animals are able to obtain nitrogen through eating plants and animals. Web the nitrogen cycle describes how nitrogen moves between plants, animals, bacteria, the atmosphere and the soil. How do animals obtain usable nitrogen? When animals eat the plants, they acquire usable nitrogen compounds. It entails some processes such as nitrogen fixation, nitrification, denitrification. The most important part of the cycle is bacteria. Nitrogen goes back into the soil through animal wastes and decomposing animals and plants. If nearly 78% of the atmosphere is made of nitrogen, how couldthere be a shortage of nitrogen in soil?
Bacteria help the nitrogen change between states so it can be used. Show the video linked below: When nitrogen is absorbed by the soil, different types of bacteria help it to Have students share their journeys. Nitrogen cycle is defined as a biogeochemical process through which nitrogen is converted into many forms, constantly passing from the atmosphere to the soil to organisms and back into the atmosphere. It entails some processes such as nitrogen fixation, nitrification, denitrification. Give the two ways nitrogen can be fixated so plants can use it togrow. In nitrogen fixation, bacteria convert \text n_2 n2 into ammonia, a form of nitrogen usable by plants. If nearly 78% of the atmosphere is made of nitrogen, how couldthere be a shortage of nitrogen in soil? The speed of decomposition is the key to keeping the nitrogen cycle moving as the majority of fixated nitrogen comes from bacteria breaking down dead matter and feces. Nitrogen goes back into the soil through animal wastes and decomposing animals and plants.
