Frequently Asked Questions
What is a terrestrial ecosystem?
Terrestrial ecosystems are land-based communities of organisms and their environments, such as forests, grasslands, deserts, and tundra. They are shaped by climate, soil, and topography.
What are the main types of freshwater ecosystems in the USA?
The USA has three primary types: Lentic (still water like lakes and ponds), Lotic (flowing water like rivers and streams), and Palustrine (wetlands such as marshes and swamps).
Why are coastal ecosystems important?
Coastal ecosystems serve as critical breeding grounds and nurseries for many species, protect inland areas from storms and erosion, filter pollutants, and support significant biodiversity.
Where can one find coral reefs in the US?
The most prominent coral reefs in the US are found off the coast of Florida, particularly in the Florida Keys National Marine Sanctuary, as well as in US territories like Hawaii and the Caribbean.
How do human activities impact US ecosystems?
Human activities like urbanization, agriculture, pollution, climate change, and habitat destruction significantly impact US ecosystems, leading to biodiversity loss, habitat fragmentation, and altered natural processes.
