Solved in 2 steps
- The most intense interactions often occur between individuals of the same species. What concept discussed in this chapter can be used to explain this phenomenon?How does a defense mechanism (behavioural, cryptic colouration, protective colouration, mimicry) affect predation and competition? a) Provide an example of a defense mechanism that you have not encountered in the course or in the online assignments. Include an image depicting the defence mechanism, describe the defence mechanism and cite your sources. b) Hypothesize how this defence mechanism may have evolved over time due to pressure from predation and/or competition.Consider the recent introduction of wolves into Yellowstone National Park. explainhow reintroducing wolves into the Yellowstone area could have such a significantimpact on the physical landscape of Yellowstone National Park.
