Ecology of Slugs research. Please answer these questions completely using quality, and correct sentences after thoroughly reading the Ecology Reasearch section. (75 pts)

1. Background: Both Slugs and Snails are native to the Pacific Northwest. Each population ferociously competes with another for the same habitat and food resources.

 

• Let's suppose you are a property owner and your property was inhabited by slugs.

• Lets also suppose that, over a period of years, you continuously enriched the soil on your property with lots and lots of calcium. Most people use granular limestone to do this. (What will adding calcium do to the slug's environment? What other creatures need calcium? Also read 1st part of Native Bananna Slug.)
