Questions and Answers

What is the key difference between native, non-native, and invasive species in aquatic environments?

Native species are those naturally found in an ecosystem, non-native species are introduced externally, and invasive species cause harm to the ecosystem. (correct)

Native species are always beneficial, while non-native and invasive species are always harmful.

Non-native species are those naturally found in an ecosystem, native species are introduced externally, and invasive species have no impact.

Non-native species are always beneficial, while native and invasive species are always harmful.

Study Notes

Soil development is influenced by five major factors: parent material, climate, living organisms, topography, and time.
Parent material can be organic or mineral and greatly influences the type and rate of soil development.
Soil properties like texture, depth of bedrock, water table, flooding, and slope directly impact soil interpretations in the field.
The Soil Capability Classification System is used to protect farmland from urban pressure by understanding and applying land capabilities.
The soil profile, with its unique characteristics in different layers, can provide valuable information about the landscape history and soil properties.
Soil scientists recognize four major processes that change parent material into soil: additions, losses, translocations, and transformations.
Conservation practices for water protection include reducing erosion, planting cover crops, creating buffer zones, and implementing livestock fencing.
