The primary consumers ( herbivores ) feed directly on producers. The secondary consumers ( carnivores ) feed on the primary consumers and the tertiary consumers feed on the secondary consumers.
The secondary consumers would increase as the tertiary consumers would not be present. Finally, as a result, a number of the primary consumers would decrease.
Cell is the structural and functional unit of life. It has various components that are important for its survival such as plasma membrane, mitochondria, endoplasmic membrane, nucleus, golgi body, etc.
Answer: At a minimum, for a cell to be alive, it must contain the following organelles:
1. Plasma membrane: It is the covering of the cell that is selectively permeable.
2. Nucleus: It contains genetic material which is important for DNA replication.
3. Mitochondria: It is the power house of the cell that synthesizes ATP.
We see that this is a region near the continents, so it is probable that there is the boundary of a tectonic plates around there. Since there are islands there, it is quite probable that there is a subduction zone near them which means that the oceanic crust is going below the continental one and the continental is slowly elevated. This also shows that the boundary is convergent, since transform boundaries do not lead to elevation. Near convergent boundaries, there are frequently volcanoes and shallow earthquakes. Finally, the climate near Alaska is cold and this does not depend on whether islands are near a boundary or not. So, 2 4 and 5 are correct. hopefully this is correct?
