Question

which of the following animals undergo metamorphosis and which do not cow,butterfly,silkmoth,humans frog, housefly,sparrow hen, mosquite,monkey

Answer 1

Most butterfly species live in the rain forest. A mere 11,250 acres of Ecuadorian rain forest has more species (676) than all of North America. Egg, larvae or caterpillar, and pupa or chrysalis are the stages of butterfly metamorphosis, before reaching the adult form. Rain forest butterflies include the Blue Morpho, Owl butterfly, Periander Metalmark, Crimson-banded Black, Tiger Longwing and Tropical Milkweed.

Ants, Termites, Bees and Beetles

The majority of invertebrates in the rain forest are ants and termites. More than 500 ant species were found in 15 acres of Malaysian rain forest compared with the total 700 species of ants found in North America. Ants, bees and beetles go through the same metamorphosis stages as butterflies. However, the metamorphosis of termites is considered an incomplete process, because the animals do not go through the chrysalis stage. This is called hemimetabolism. The Tortoise beetle, the ants of the genus Polyergus, the South American bee and the Cubitermes termites of Africa are some examples of insects that go through metamorphosis.

Grasshoppers and Dragonflies

Similar to termites, grasshoppers and dragonflies don't go through the chrysalis stage during their development. Instead, they pass through several nymph stages, when the young animals hatch already looking like an adult and change their external skeleton during growth. There are more than 2,000 identified species of grasshopper in the rain forest, including species of the genus Rhachicreagra. The Nietner's Shadowdamsel, the Two-spotted Threadtail, the Jungle Threadtail and the Rivulet Tiger are some dragonflies found in the Sri Lanka rain forest.

Spiders and Scorpions

Rain forest spiders include many species of tarantulas, such as the Bird Eating Goliath, with a leg-span of 10 inches; the venomous Brazilian Wandering Spider; the white-and-black Tropica Tent-Web Spider; and various species of jumping spiders, such as the herbivorous Bagheera kiplingi, found in Mexico. Although most species of scorpions live in dry habitats such as deserts, some species are adapted to live in the hot and humid rain forest. The mildly venomous Australian rain forest scorpion is an example. Spiders and scorpions go through an incomplete metamorphosis.

Frogs

Frogs spend the early stages of their life cycle in the water as eggs and tadpoles. Through the metamorphosis, the exterior gills are replaced by lungs, back legs and front legs appear and the juveniles lose their tails. In the rain forest, some frogs such as the Green and Black Dart and the Blue Dart have bright colors, which is an indication of their venom. However, some colorful species, such as the red-eyed tree frog, is not toxic to humans.

Answer 2

• the animals who undergo metamorphosis are butterfly, silk moth, frog, housefly and mosquito.
• the animals who do not undergo metamorphosis are cow, humans, , sparrow, hen and monkey.
• metamorphosis is the biological process where the organisms under go biological and physical changes after the birth. for example - the metamorphosis of the mosquito have four stages : egg, larva, pupa and adult
• organisms like humans do not show metamorphosis as there no physical changes of the human baby after birth.
