The types of herbaceous plants changed at different times during succession. For example, ragweed (which grows well in full sun and completes its life cycle in one year) was very common in the first year after a farm field was abandoned, but less common in later years. In contrast, wild strawberry (which can grow in partial shade and grows back each spring from its roots) was more common in years 25-40. Explain the likely reasons for these changes in the types of plants at different times during succession.

compost can be added to topsoil as a:

pesticide

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
