Competition for light, water, and nutrients is intense among the land plants. plant success is generally related to photosynthesis, so evolution has resulted in many structural adaptations for efficiently acquiring light from the sun and co2 from the air. as you read this section, focus on how this is accomplished. let's look first at adaptations to increase light capture. how do plants reduce self-shading?

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.  

several tissues working together form an organ, and several organs together make up an organisms.

the group of cell that carries out special jobs are tissue.
