Insectivorous plants trap insects to get______.

Options

A. oxygen
B. hydrogen
C. carbon dioxide
D. nitrogen

Explanation

**Step-by-Step Solution:**

1. **Understanding Insectivorous Plants**: Insectivorous plants are specialized plants that have adapted to capture and digest insects. This adaptation is primarily due to their nutrient requirements.

2. **Nutrient Needs**: Unlike most plants that obtain their nutrients, particularly nitrogen, from the soil through nitrates, insectivorous plants have evolved to trap insects to fulfill their nitrogen needs.

3. **Why Nitrogen?**: Nitrogen is an essential nutrient for plant growth. It is a key component of amino acids, proteins, and nucleic acids, which are crucial for the development and functioning of the plant.

4. **The Process of Trapping**: These plants have developed various mechanisms to trap insects, such as sticky surfaces, snap traps, or pitfall traps. Once the insects are trapped, the plant secretes digestive enzymes to break down the insect's body, allowing it to absorb the nitrogen-rich compounds.

5. **Conclusion**: Since insectivorous plants cannot obtain nitrogen from the soil, they rely on trapping insects to meet their nitrogen requirements. Therefore, the correct answer to the question is that insectivorous plants trap insects to get **nitrogen**.

**Final Answer**: Insectivorous plants trap insects to get **nitrogen**.
