3)What is the habitat of cactus?
4)What are the sequence of hierarchy classification?
Answers
1. Frogs can also breathe through their skin. They need to keep their skin moist to be able to breathe through their skin, so if their skin dries out they are not able to absorb oxygen. They use their skin to absorb oxygen when underwater, but if there is not enough oxygen in the water, they will drown.
2. Those who can fly, soar or glide easily in the air are aerial animals.
3. Most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on earth. Cacti show many adaptations to conserve water.
4. When an organism is classified into various categories, a hierarchy is maintained. Accordingly, an organism belongs to Kingdom, Phylum, Class, Order, Family, Genus and Species in hierarchical order.
