identify whether the following scenario is an example of increasing or decreasing competition and intraspecific or interspecific competition.

Zebra mussels being introduced to the Great Lakes __________,___________
Culling the wolf population in Northern Alberta to preserve the caribou population________________-,________________
Cichlids in Lake Victoria, evolving into more than 500 different species ________________,_________________
Bison population migrating from B.C. to Northern Alberta during mating season______________,____________

Expert Solution

a. Increasing interspecific competition

When density of the population increases, the competition becomes more. Interspecific competition is a competition between different species. When Zebra mussels are introduced into the Great lakes, it proliferated like an invasive species hindering the growth of other species in the water, So this is an example of increasing interspecific competition.

b.Decreasing interspecific competition

Wolfs were attacking caribou population. So in order to prevent the vulnerable population going extinct, they decided to reduce the wolf population by killing some of the wolfs. This reduces the competition between species.

c. Increasing intraspecific competition

Here the population of Cichlids in Lake Victoria increases which leads to competition between Cichilds.

d.Decreasing interspecific competition

Bisons migrate to protect themselves and their calfs from the attack of other species.

5. International trade and development Identify whether each scenario in the following table is an example or foreign aid, import substitution, or export promotion. Scenario Development Strategy Foreign Aid Import Substitution Export Promotion After World War II, the Argentine government actively supported domestic production of textiles, leather, and home appliances in an effort to become more self-sufficient and less reliant on foreign goods. In 1991 and 1992, the World Bank gave over 45% of its concessional assistance—grants or loans at...

4. Given the elasticity, determine whether increasing/decreasing the price will increase/decrease the revenue for a firm. For instance, let's say that the price elasticity of demand is -2 between P=8 and P=10. Would a firm's revenue increase if it raises its price from 8 to 10? If you already know the price elasticity, this question does not require calculation.
