Insects do not have respiratory pigments in their blood. They are able to survive with low oxygen in the blood because some can respire through pores on the skin.
because it`s tracheas bring O2 to cells
yes they could
No!! Insects are needed for us to survive on earth! They help create the carbon dioxide on earth.
3. its respiratory surface is in direct contact with a watery environment
Protection from natural enemies is the way in which camouflage helps insects to survive. Camouflage may involve taking on predominant colors in an environment or predominant coloration and shapes. It means that insects can enjoy such activities as feeding, mating, and resting without interruptions.
Sundews can survive without eating meat if they are growing in good soil. They only consume insects because the soil they grow in lacks important nutrients.
All insects have a tracheal system of air tubes rather than a complex lung based respiratory system. These air tubes allows the insects to breathe without weighing down their small bodies with complicated organs.
The cardiovascular systemworks with the respiratory system by transferring the oxygen into the blood and then the heart pumps the blood throughout the body. Without the lungs and heart we wouldn't be able to survive.
If you didn't have your respiratory system it would not be possible for you to be alive. The body requires oxygen to survive, which makes the respiratory necessary because it is through our respiratory system that we receive oxygen.
the bark protects trees from diseases and insects, it is pretty rare that a tree can live without it's bark for protection.
it helps them get there small prey like mice insects and small birds without bending over
Soil takes a long time to build up, and without it, many plants cannot survive. Without plants, there can be very few insects or other animals that can live there.
