1. What is the primary characteristic of mollisols and in what biome is it found?
2. Name and define 3 different types of savannas.
3. If the population of a keystone species rapidly decreases, what is the effect on the ecosystem? What happens with an indicator species?

1. characterized by a dark surface layer rich in organic matter & high concentrations of calcium & magnesium. Highly organic matter soil found in grasslands
2.Edaphic savannas are caused by soil conditions & are not entirely maintained by fire. Climatic savannas are a result of climatic conditions. Derived Savannas are a result of people clearing forest land for cultivation. Farmers cut down trees, burn them & plant crops in the ashes. Grass then takes over the bare ground (it grows very fast & has deep roots to soak up water.). Annual fires maintain the area as a savanna. The soil is porous with rapid drainage of water. There’s a thin layer of humus (organic plant material) that provides vegetation with nutrients. The predominant vegetation consists of grasses & forbs. Different savannas support different grasses due to disparities in rainfall & soil. Deciduous trees & shrubs are scattered across the open landscape.
3. overall population of ecosystem decrease. the health of the ecosystem decreases

Correct, your turn (also you pretty much just copied and pasted our notesheet for the second question, you could have given more concise answers.)

yeah thats correct

Question: What are some purposes of having large front paws for a badger in grasslands?

Badgers who live in grasslands have large front paws to burrow in the ground and build dens, to catch prey, and to dig up plants.

In case you didn't see, Fillychi was supposed to tell me if my answer was wrong or right and then it would have been my turn to ask a question. It's okay, though, because I'm answering this one and I'll write the next one.

1) increase in carbon dioxide
2) species extinction
3) loss of biodiversity
