Question

Aldrovanda is
A. Primary producer
B. Secondary consumer
C. Carnivores plant
D. None of the above

Answer 1

Aldrovanda is a tiny, free-floating aquatic plant in which roots are absent. The length of the whorl is about 1-2 cm and the height of the plant is about 1.5-20 cm. The structure of leaves is very similar to that of Venus flytrap. The main difference is the presence of air chambers in the stem region. The common name of Aldrovanda is the waterwheel plant.

Complete answer:
A primary producer is an organism which transforms an abiotic energy source (such as light) into energy reserved in organic compounds and which can also be utilized by other living creatures. They are present at the lowest trophic level. Secondary consumers are those animals which consume plants or live on plant matter and when they respirate, release energy and carbon dioxide. In simpler words, they are herbivores. Carnivores are defined as those creatures that feed on other animals or simply those animals which feed on the flesh of animals. Hence are known as "meat-eaters". Carnivores are known as predators and herbivores are the prey. Aldrovanda is a genus of carnivorous plants containing extinct species such as Aldrovanda vesiculosa (waterwheel plant) and various extinct taxa. The main function of the Aldrovanda is to trap the carnivore underwater.

So, the correct answer is Option C.

Note: It is known as the waterwheel plant because the isolated whorl of leaves and even the slice from a stem resembles the shape of the wheel. Carnivores hunt down and slaughter other creatures; they need a huge amount of calories. So, it means they have to eat several other creatures over the year. In simple terms, the bigger the size of a carnivore the more it requires to eat food.
