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 animal’s proteins.

Explanation:

altitude, density, pressure

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
