Carnivorous plants must rely on insects for nitrogen since they are found in soils with low nitrogen levels. Since the soil can't provide them with enough nitrogen, they must consume insects to meet their nitrogen requirements.
Carnivorous plants obtain nitrogen by capturing and digesting insects using specialized mechanisms such as sticky traps or pitcher leaves. They absorb the nitrogen released from the breakdown of the insects' bodies as a nutrient source due to the nitrogen-poor environments they typically grow in.
The question is not why these plants use photosynthesis, it's why they are insectivorous! All plants use photosynthesis, but only some of them live in such poor soil that they have adapted this unusual method of obtaining nutrients. Insectivorous plants get nutrition from more than one source. Insects are primarily a source of protein, and photosynthesis is a source of carbohydrates. Plants need a lot of carbohydrates, in order to grow.
Pitcher plants eat insects as a source of nutrients, particularly nitrogen. These plants typically grow in nutrient-poor soil, so they have evolved to supplement their diet by trapping and digesting insects in their pitcher-shaped leaves. This adaptation allows them to thrive in environments where other plants struggle to survive.
Animals get nitrogen from plants.
Yes, plants can use ammonia as a source of nitrogen for their growth and development.
Yes, a venus fly trap does perform photosynthesis and it does fix CO2.It consumes insects largely as a source of nitrogen. Most plants getnitrogen from the soil - this is the reason we fertilize our crops andapply "plant food" to houseplants. But venus fly traps live in placeswhere the soils are very poor in nitrogen. The insects give them asupplemental nitrogen source.
The source of nitrogen's for carnivores (meat eating animals) is by EATING HERBIVORES they eat plants and the plants have the nitrogen by the soil... ect...
Most plants absorb nitrogen from Nirates in the soil. A notable exception are insectivorous plants such as the Venus Fly Trap, which lives in soils which do not have much Nitrogen - so have adapted to obtain it from another source.
1. The pitcher shape to trap insects inside. 2. The aroma to attract insects. 3. Hair growing downward to stop insects from escaping. 4. Using insects as a source of nitrogen in an environment low in nitrogen.
The plants eat small insects and animals because the soil they grow in do not provide the specific amount of nutrients for plants to grow well. However, they do carry out photosynthesis. It is just their nature that they can only grow in the soil with less nutrients because they have another source of consuming nutrients, if they consumed the specific amount of nutrients as well as nutrients from their prey they would not be able to absorb all the nutrients and this source of consuming small insects would be of no use.
Nitrogen can also be used in the form of ammonia as a fertilizer for plants. Ammonia provides a readily available nitrogen source for plants to support their growth and productivity.
Ammonia is the richest source of nitrogen because it contains the highest percentage of nitrogen by weight compared to other nitrogen-containing compounds. This makes it highly efficient in supplying plants with the necessary nitrogen for growth and development.
