Here's why:
* They're still plants: Carnivorous plants are classified as plants, just like any other tree, flower, or grass.
* Photosynthesis is essential: Like all plants, carnivorous plants need to photosynthesize to create their own food (sugar) using sunlight, water, and carbon dioxide.
* Extra nutrients: They obtain extra nutrients like nitrogen and phosphorus from digesting insects and other small creatures. This helps them thrive in nutrient-poor environments where other plants struggle.
So, while carnivorous plants have a unique way of supplementing their diets, they still rely on photosynthesis as their primary source of energy.
