Question

use your understanding of the nitrogen cycle to answer the questions provided. the nitrogen cycle could not exist without → bacteria x. complete put the steps of the carbon cycle in order using step 1 as your starting point. step 1: bacteria, through nitrogen fixation and nitrification, convert nitrogen into a usable form. the animal dies and decomposes, returning nitrogen back to the soil. once nitrogen is in usable form, it is taken up by plants and assimilated into proteins. an animal eats a plant and the nitrogen becomes part of the animals proteins. done

Explanation:

Step1: Start with nitrogen conversion by bacteria

Bacteria convert nitrogen through fixation and nitrification.

Step2: Plants take up usable nitrogen

Once nitrogen is usable, plants assimilate it into proteins.

Step3: Animals consume plants

An animal eats a plant, and nitrogen enters animal proteins.

Step4: Nitrogen returns to soil

The animal dies and decomposes, returning nitrogen to the soil.

Answer:

1. Once nitrogen is in usable form, it is taken up by plants and assimilated into proteins.
2. An animal eats a plant and the nitrogen becomes part of the animal's proteins.
3. The animal dies and decomposes, returning nitrogen back to the soil.
