Question

List five conditions that are necessary for respiration.

State the respiratory organs of the following organisms:
a. Insect
b. Tadpoles
c. Flowering plants
d. Spider
e. Birds
f. Earthworm
g. Amphibians

Answer 1

Insects have tracheae, tadpoles respire through gills, adult frogs use lungs and skin, flowering plants have stomata, spiders have book lungs, birds have lungs and air sacs, earthworms respire through their skin, and amphibians use their skin.

Step-by-step explanation:

Insects have a system of tubes called tracheae that deliver oxygen directly to their cells. Tadpoles respire through gills, while adult frogs use both their lungs and their skin to breathe. Flowering plants have small pores called stomata on their leaves and stems that allow for gas exchange.

Spiders have book lungs, which are specialized respiratory structures consisting of stacked plates that allow for gas exchange. Birds have lungs similar to mammals but also have air sacs that help facilitate efficient oxygen uptake during flight. Earthworms exchange gases through their skin. Amphibians, like frogs, use their skin for gas exchange.
