Which organism is a producer in this ecosystem? Fox Weasel Hawk Thrush Mouse Rabbit Squirrel Caterpillar Grass Shrubs Mushroom Shrubs

It could be shrubs or grass

Explanation:

Producers in ecosystems are autotrophic organisms, that means organisms that can synthesise their own food and do not rely on other organisms to provide food to them. Plants do this via photosynthesis - therefore plants are the producers of ecosystems.

Herbivores (such as caterpillars and thrushes) are primary consumers. Carnivores (such as weasels and foxes) are secondary/tertiary consumers, depending on the number of trophic levels.

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.
