What is prey catching pitcher plant ?Pitfall traps, a prey-trapping mechanism with a deep hollow filled with digesting fluid, are modified leaves on a kind of carnivorous plants known as pitcher plants. Specialized leaves are used to create the traps in what are known as "genuine" pitcher plants. Using nectar, the plants draw in and suffocate their victim.
Flying, flying, or crawling insects that are out foraging are drawn to the hollow created by the cupped leaf by visual cues such nectar and anthocyanin colors.
Insects fall into the trap because the pitcher is slippery after being saturated by dew or nectar. To aid in preventing escape, the walls of the pitfall may be covered in waxy scales, protruding aldehyde crystals, cuticular folds, downward-pointing hairs, or lunate cells that originate from guard cells.
The sharp curved beak of penguin helps to easily catch their pray. Therefore, option A is correct.

How can a force act directly on an object? Explain.
Answer:
The quantity of force is expressed by the product of mass (m) and acceleration (a). Mathematically the equation can be written as
F = ma
Where,
F= Force
m = mass
a = acceleration
When a force acts on an object the objects the objects have different effects of force. So let us know about the effects of force on an object.
Explanation:
Answer:
Explanation:
An applied force is a force that is applied to an object by a person or another object. If a person is pushing a desk across the room, then there is an applied force acting upon the object.
