1. What is the most common type of dispersion.
2. Name three examples of non-point source pollution.
3. What roles do lichen and moss play in succession?
4.Name an example of endosymbiosis with organisms in the grasslands.
1. Clumped dispersion.
2. Excess fertilizer, herbicides/insecticides, toxic chemicals from urban runoff.
3. They are the pioneer species in primary succession.
4. Soybean plants harbor Rhizobium, a bacterium that converts atmospheric nitrogen into something that plants use for creating proteins.

1. What is the difference between allopatric and sympatric speciation?
2. Why is there less biodiversity in deserts?
3. Why do so few natural prairies remain?
4. Name 4 effects (2 negative/2 positive) of acid rain.

1. What is the difference between allopatric and sympatric speciation?
2. Why is there less biodiversity in deserts?
3. Why do so few natural prairies remain?
4. Name 4 effects (2 negative/2 positive) of acid rain.
1. Allopatric speciation involves geographic separation between different groups, whereas sympatric involves the creation of a new species in the same geographic area. Of the two, allopatric is much more common.
2. There are fewer resources, and thus the biome can support fewer organisms. Further, the dry and hot climate makes it difficult for most organisms to live there.
3. The flat land and fertile soil are great for agriculture, so most of them have been converted to agricultural land by humans.
4. Pos: Suppreses methane production from wetlands (leading to lower greenhouse gases overall), nitrogen in acid rain allows trees to store more carbon and increase productivity
Neg: Increased acidity of bodies of water, leaches aluminum from soil

4. Name a benefit and a harm of parthenogenesis.
1. Thomas Malthus created the idea of Malthusian growth, in which population increases geometrically, but food increases arithmetically.
2. a) some frogs use aposematic coloration to warn others that they are poisonous. b) stick bugs camouflage within trees to avoid detection by predators.
3. Frequent fires prevent trees from growing in temperate grasslands.
4. If individuals become isolated, this is a method to reproduce without a second organism present. However, it limits genetic diversity.

1. What is the difference between Batesian and Mullerian mimicry?
2. Why do some deserts contain Entisols, rather than Aridisols?
3. How does eutrophication affect the properties of the water it occurs in?

2. Why do some deserts contain Entisols, rather than Aridisols?
3. How does eutrophication affect the properties of the water it occurs in?
1. Müllerian mimicry is when multiple species share the same warning coloration, but all of them have defenses and Batesian is when harmless species mimics aposematic coloration of harmful one
2.They are very dry
3. Eutrophication increased dissolved oxygen in the water
