48. How do matter and energy differ within a community? Use the words recycle, trophic level,
and flow in your answer. (2.4-2.6)

47.. in this case , the longer the food chain , the less energy is available for the rest of the members of the food chain. this indicates that a food chain with 15 trophic levels contain an energy that is insufficient to sustain all its members

48...Matter is cycled through the ecosystem in the biogeochemical cycles. ... However, energy is not recycled, but it flows into the ecosystem through the feeding relationships between the organisms in different trophic levels.

49.. (a) ...Urban development can magnify the risk of environmental hazards such as flash flooding. Pollution and physical barriers to root growth promote loss of urban tree cover. Animal populations are inhibited by toxic substances, vehicles, and the loss of habitat and food sources.

Explanation:

#keep learning!!

it's unlikely a majority of a large population would agree on issues

hope this : )

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.
