Can you solve this food-themed puzzle? I need to find protein-rich food items that contain essential amino acids for the human body. The twist is, I want you to categorize them based on their sources (plant-based, animal-based) and list their protein concentrations per serving in descending order. Can you do it? Check out the HTML table below for the protein concentration data: 
<!DOCTYPE html>

	<table>
		<tr>
			<th>Food Item</th>
			<th>Protein Source</th>
			<th>Protein Concentration per Serving (g)</th>

			<td>Chicken Breast</td>
			<td>Animal-based</td>
			<td>26</td>
		</tr>
		<tr>
			<td>Salmon</td>
			<td>Animal-based</td>
			<td>22</td>

Sure, I'd be happy to help with this puzzle. Here's your answer:

1. Food Item | Protein Source | Protein Concentration per Serving (g)
2. Chicken Breast | Animal-based | 26
3. Salmon | Animal-based | 22
4. Tofu | Plant-based | 10
5. Chickpeas | Plant-based | 7.3
6. Quinoa | Plant-based | 8.1

Chicken breast and salmon are animal-based sources of protein, while tofu and chickpeas are plant-based sources. Quinoa is a unique plant-based food that contains all nine essential amino acids in sufficient quantities, making it a complete protein.

In terms of rankings, here's the descending order of protein concentrations per serving:
1. Chicken Breast - 26g
2. Salmon - 22g
3. Quinoa - 8.1g
4. Tofu - 10g
5. Chickpeas - 7.3g

However, it's essential to note that protein requirements vary depending on age, gender, weight, height, and physical activity level. Therefore, consulting a registered dietitian can be helpful in determining the appropriate protein intake for individual needs.

Sure, I'd be happy to help you sort this data. Here are the protein-rich food items categorized based on their sources and listed in descending order of protein concentration per serving:

**Animal-based:**
1. Chicken Breast: 26g
2. Salmon: 22g

**Plant-based:**
1. Tofu: 10g
2. Quinoa: 8.1g
3. Chickpeas: 7.3g

These food items are all good sources of protein and contain essential amino acids for the human body.
