The diagram below shows the different paths nitrogen can take in the nitrogen cycle. Below are some of the steps of the nitrogen cycle. Use three of the steps to show a possible way nitrogen can move through an ecosystem.

Here are the tiles (only 3 will be used)

Nitrates

Assimilation

Atmospheric

Ammonium

Ammonification

What is the significance of the protein-lined pits? a. protein attracts other proteins needed for atp synthesis within the cell. b. protein-lined pits are able to transport one molecule at a time down the concentration gradient within the cell. c. the polarity of proteins allows other polar molecules to attach and be transported in the cell by transport channels. d. receptors within the pits allow ligands to fuse and be transported into the cell by endocytosis.
