Answer:
The best description of the likely impact of an invasive plant species on a warm ecosystem is:
The invasive plant species take over resources used by native plant species. Some plant species decrease in population, affecting the food source for consumers in the ecosystem.
Invasive plant species have the ability to outcompete native plant species for resources such as sunlight, water, and nutrients. This can lead to a decrease in the population of native plant species as they are unable to access sufficient resources to thrive. As a result, the food source for consumers in the ecosystem may be affected, leading to potential changes in the population dynamics of the consumer species.
