You have an ecosystem with the following organisms: birds, fruit trees, tigers, and monkeys. which list would best describe the food chain? a. tigers, monkeys, birds, fruit treesb. birds, fruit trees, monkeys, tigersc. fruit trees, birds, tigers, monkeysd. fruit trees, birds/monkeys, tigers

D. Fruit trees, birds/monkeys, tigers

Explanation:

Fruit trees are the primary producers and produce fruits and other plant parts as food for birds. Monkeys are omnivorous and derive nutrition from eggs of birds or fruits, seeds and other parts of the plant. Tigers are top consumers and are carnivores as they feed on monkeys and even birds. Therefore, the given ecosystem may have the following food chain:

Fruit trees (first trophic level and producers)> birds /monkeys (second trophic level and first consumers)---> tigers (third trophic level and top consumers).

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.  

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
