Then the model will become useless. originally the bottle should be air tight only tubes connected to the balloons, so that pressure can be shown when you adjust the plastic sheet in the bottom of the model. but now if there's a hole, air can move freely in or out the bottle and the model will not be able to show anything that occurs during respiration

Terrestrial
Terrestrial ecosystems are land systems such as forests, deserts, grasslands, tundras and coastal regions. Depending on the biome's climate, more than one terrestrial ecosystem can be present. For example, tundras have less plant life because of lower temperatures; deserts produce fewer plants because of higher temperatures. A forest or grassland may have an extreme variety of plant life because its biome has the right amount of sunlight and moisture for many ecosystems, and species, to grow.
Lentic
Lentic is a class of aquatic ecosystems that are found on land, such as ponds, rivers, lakes, swamps and streams. Mostly, lentic ecosystems are described as still bodies of fresh water, and they are smaller ecosystems. Some lentic ecosystems contain animals and microorganisms, but they mostly rely on photosynthesis of algae and underwater plants to produce energy to thrive. One of the requirements of a lentic body of water is that it is exposed to the sun to encourage photosynthesis.
