your answer is B low-pressure systems that cause stormy weather
Answer:
45 meters
Explanation:
If it takes the slug 20 minutes to travel 15 meters, you multiply the 15 by three to get the distance for 60 minutes.
Out of the three you gave ecosystem is what I would call the most broad. An ecosystem includes living AND non-living things in an area
Community is all the LIVING things in an area (plants are included and I think bacteria is too, but I'm not sure)
Population is pretty narrow it just looks at specific species in one area. Population of mosquitoes doesn't include butterflies, if only looks at mosquitoes
Hope this helped!
