Which snail species had a higher population in part 1? What adaptations aided in their survival?

Answer 1

In Part 1, the snail species with a higher population was the brown garden snail (Cornu aspersum). Some adaptations that aided in their survival include:

1. Shell shape and thickness: The brown garden snail has a protective shell that is both thick and hard, providing defense against predators and harsh environmental conditions.

2. Ability to aestivate: When faced with unfavorable conditions such as drought or extreme temperatures, brown garden snails can aestivate, which involves withdrawing into their shells and sealing themselves off with a thin layer of mucus, reducing water loss and metabolic activity.

3. Herbivorous diet: Brown garden snails feed on a wide range of plants, giving them access to a diverse food source, which increases their chances of survival by reducing competition.

4. Moisture retention: These snails have a mucus secretion that helps them retain moisture, even in dry environments. This adaptation reduces the risk of dehydration and allows them to thrive in a variety of habitats.

Overall, these adaptations have contributed to the higher population of the brown garden snail in Part 1.
