Together with the four species of echidna, it is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth to live young. These are among the few venomous mammals.
Males have a spur on the back of their hind feet that is connected to a venom-secreting gland.
International Union for Conservation of Nature (IUCN) recently downgraded the platypus conservation status to Near Threatened from Least Concern.

Ecological Significance

The Platypus eats all kinds of insect larvae, molluscs, crustacean, fish eggs and sometimes frogs. Since the platypus is a carnivore, it plays the typical role of the carnivore in an ecosystem. It keeps the populations of species in lower levels of the food chain in check.

Miyawaki Method

Consider the following statements with reference to the Miyawaki method:

Miyawaki is a technique pioneered by Philippines that helps build dense, native forests.

The close cropping further ensures that the plants receive sunlight only from the top thus enabling them only to grow upwards than sideways.

	A	Only 1

	B	Both 1 and 2

	C	Only 2

	D	Neither 1 nor 2

Your Ans is

Right ans is C

Your Answer Is Correct

Your Answer Is Wrong

Explanation :

Miyawaki is a technique pioneered by Japanese botanist Akira Miyawaki that helps build dense, native forests.
It involves planting dozens of native species in the same area, and becomes maintenance-free after the first three years.
In this, multi-layered saplings are planted close to each other. This blocks sunlight from reaching the ground and prevents weeds from growing, thus keeping the soil moist. The close cropping further ensures that the plants receive sunlight only from the top thus enabling them only to grow upwards than sideways.
The approach is supposed to ensure that plant growth is 10 times faster and the resulting plantation is 30 times denser than usual.
