False Indicate the answer choice that best completes the statement or answers the question 30. A forested slope is set to be logged. Which method will minimize erosion and protect the stream at the base of the slope from being polluted by excess sediment? a. clear-cutting b. strip cutting c. second-growth cutting d. surface cutting e. crown cutting 31. is the number and variety of species present in any biological community. a. Biome diversity b. Ecological diversity c. Functional diversity d. Species diversity e. Genetic diversityExplanation / Answer
1) One of the causes of extinction is human population growth.?
ANSWER is : True
EXPLANATION:
One of the causes of extinction is human population growth as overconsumption causes extinction. If human populations continue to expand then humans use more resources which results in increased habitat destruction.
2) A forested slope is set to be logged. Which method will minimize erosion and protect the stream at the base of the slope from being polluted by excess sediment??
ANSWER is: surface cutting
EXPLANATION:
Farming, construction, logging, and mining increase the potential for erosion and sediment.
Erosion is often increased by removal of protective natural vegetation and also placement of impermeable surfaces like paving and rooftops on or over the soil.
Soil erosion in slopes caused by heavy rainfall and surface runoff that is a serious problem in agricultural areas such as on inclined slopes in which the soil loss can reduce soil productivity
Trees, shrubs, and groundcovers can maintain slopes and reduce erosion from surface water.
3) ____ is the number and variety of species present in any biological community.?
ANSWER is: species diversity
species diversity referred to as the number of species and abundance of each species in particular location.
Biological community is an interacting group of various species in a common location.
