1. Why is Mt. St. Helens considered a "research lab?" 2. What were the first "pioneer species" to the pumice plain?

3. How did these Pioneer Species work together to create ideal soil for plant life?

4. How have Roosevelt Elk helped the process of ecological succession in the Mt. St. Helens blast zone?

5. How do you think the Rainbow Trout got back into Silver Lake?

6. What are at least three questions you have about the video after watching it?

primary succession begins with a bare rock and ends with a forest secondary succession begins after a natural disaster where there is a temporary setback after a forest fire or local destruction, but the surrounding area can fill in

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

where is the scientific experiment?
