The aquarium was sealed and placed at a bright corner. After two weeks, both the number of water plants and water snails increased.
(a) Besides their gaseous needs, state one other way in which the water snail and the water plant are interdependent.
water snail uses O2, expels CO2, water plant uses that CO2 and expels O2.
thank youu
To determine one other way in which water snails and water plants are interdependent, we need to understand their ecological relationship. In this case, we can infer that the increase in both the number of water plants and water snails is a result of favorable conditions in the sealed aquarium.
One possible way in which water snails and water plants are interdependent is through nutrient cycling. Water snails feed on dead plant material and algae present in the aquarium. They break down this organic matter and excrete waste, releasing nutrients such as nitrogen and phosphorus back into the water.
These nutrients are then utilized by the water plants for growth and photosynthesis. The water plants, in turn, produce oxygen through photosynthesis, which is essential for the survival of the water snails.
Therefore, an interdependence between water snails and water plants in this scenario is the cycling of nutrients. The water snails provide nutrients for the growth of water plants, while the water plants produce oxygen for the water snails' respiration.
