In the spring, a vegetable garden has part of it left empty in order to observe ______ succession, in which it is most likely weeds and grasses will grow first. ecological
After a catastrophic event wildfire that clears the land of all plants and trees, what will grow before the trees? weeds
A certain species of plant indicates that as the amount of phosphorous in the soil decrease, the number of plants of this species that survive to reproduce also decrease, it is likely that the plants compete for the resource of the _____ in the soil. phosphorous
TRUE or FALSE: Biodiversity contributes to the sustainability of an ecosystem due to the presence of a variety of herbivore species that can feed on a large number of different producer species. TRUE
The _____ a habitat's biodiversity, the greater will be that habitat's sustainability over time with varying conditions. greater
TRUE or FALSE: Weeds do better than other plants early on because they require fewer nutrients to grow. TRUE
Both primary and secondary succession begin with _____ species that modify the area and allow larger and more complex organism to appear. pioneer

TRUE or FALSE: Biodiversity contributes to the sustainability of an ecosystem because the greater genetic variation within species makes it more likely that some individuals will survive a disease outbreak. TRUE
