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.

Re: Ecology B/C
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?

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

Re: Ecology B/C
This sounds like a stupid question but its valid. Why are deserts so dry?

Re: Ecology B/C
Deserts are so dry because there is very little precipitation/humidity.
