Squirrels living in Iroquois Park collect acorns for food to eat and also to store for the winter months. One summer the oak trees (they grow from acorns) contracted a fungus and began to die. The same year was very hot and not much rain fell so the steaks were dry most of the year. A) Using information from the above scenario, what is one BIOTIC factor that limits the growth of the squirrel population?

B) Using information from the above scenario, what is one ABIOTIC factor that limits the growth of the squirrel population?

The correct answer is -

A)  Fungal contraction to the oak tree

B) Less precipitation.

Explanation:

A biotic factor is the living thing present in an ecosystem and affects the system and leads to changes in the system. Here fungus is a living organism that influences the population size of the oak tree and the squirrels negatively.

An abiotic factor is a non-living thing condition or factor that affects the system and leads to the changes. In this case, the high temperature and the low rate of precipitation lead to changes in the size of the population.

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
