Hello
The pH range of tolerance for humans is well defined and very small for a number of reasons.
First, we must understand that all biological reactions in our body are carried out by biological catalysts called enzymes. These enzymes operate under specific pH and and temperature conditions. Deviation from these conditions will result in inefficiency of the enzymes' functions. This may be observed macroscopic-ally as poor digestion among other things.
Next, an equilibrium is necessary for the movement of CO2 in red blood cells. CO2 is kept in equilibrium in the form of carbonic acid. This equilibrium may be disturbed by the change in pH; resulting in a difficulty to breathe.
Other effects such as fatigue, headaches and nausea may also be observed as the blood circulates throughout your body and its functions will be impaired by the changed pH.
Adaptations are what organisms do in order for them to survive and adapt to the environments that Mother Nature is presenting them.
1. Crocodiles - have tough and scaled skin that allows them to camouflage and catch prey in the water
2. Frogs - have developed bodily fluids that secrete poison to prevent predators from attacking them
3. Bats - have developed their echolocation to help them in hunting for food at night time.
4. Coelachants - have maintained their extra fins for sensory motor in the water
5. Lampreys - have maintained their tooth-funnel like mouths in order to feed on their hosts.
Answer:
A food web (<em>or</em><em> </em><em>foo</em><em>d</em><em> </em><em>cycle</em>) is the natural interconnection of food chains and a graphical representation(<em>usually</em><em> </em><em>a</em><em>n</em><em> </em><em>image</em>) of what-eats-what in an ecological community.Another name for food web is consumer- resource system.
If an ecosystem has experienced a flood, small annual plants are the type of plants you can expect to see growing first after the flood.
