Hydrilla (hydrilla verticillata) is an invasive aquatic plant and one of the most serious aquatic pests in florida. hydrilla has already been introduced to hundreds of bodies of water throughout florida. hydrilla is difficult to control because it grows rapidly and survives in many different water depths and conditions. part a: describe how hydrilla affects native plant and animal species. include both a biotic and an abiotic limiting factor. part b: suggest one biotic and one abiotic recommendation that could slow the spread of hydrilla.

Part A: Invasive species displace native species in their habitat hence reducing biodiversity that is necessary for a balanced ecosystem. This is because invasive species do not have a natural predator in their new environment and hence their growth is unchecked. They, therefore, take up much of the nutrients and other biotic factors utilized  by the other species.

Part B; To deal with invasive species, one can introduce a predator of the invasive species into the environment. Another is the influencing a limiting factor (usually an abiotic factor) that affects the invasive species specifically.  These will check the unregulated growth of invasive species and preserve the ecosystem’s biodiversity.

answer: c.

explanation:

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
