1. Snails carry out respiration only 2. Aquatic plants carry out both respiration and photosynthesis Although the aquatic plants can absorb carbon dioxide and release oxygen through photosynthesis, the amount of snail is much more than that of the aquatic plants. During night time,the absence of light prevent the plants from carrying out photosynthesis. No oxygen is released at this time. There is a net release of carbon dioxide in the closed system and hence the snail died of suffocation.

bottleneck effect. The bottleneck effect is a sudden and high reduction of a
population's genetic pool due to environmental actions (such as flood) or human
activities.
