What nutrients do insect-eating plants gain from prey?

Insect-eating plants get vital nutrients—mainly nitrogen and phosphorus—from their prey to make up for the poor nutrients in the soil they grow in. After capturing and digesting insects with enzymes, the plants absorb these nutrients. Nitrogen is especially important for making proteins and chlorophyll, while other minerals like potassium, calcium, and magnesium are also taken in to support growth.

Key nutrients gained from prey

• Nitrogen (N): Builds proteins, DNA, and chlorophyll, which is essential for photosynthesis.
• Phosphorus (P): Important for energy transfer and overall plant growth.
• Other minerals: Insects also provide potassium (K), calcium (Ca), and magnesium (Mg), which support healthy development.

How the process works

1. Trapping: The plant uses special structures (like Venus flytraps or pitchers) to catch insects.
2. Digestion: Enzymes break down the insect’s body.
3. Absorption: The plant absorbs dissolved nutrients such as nitrogen and phosphorus.
4. Growth: These nutrients fuel photosynthesis, growth, and seed production.
