The squirrels in my neighborhood are very active. At the beginning of the year, we had 11 squirrels living in our backyard. Our neighbors renovated their house and 5 of the squirrels moved away. Once the renovations were complete in late spring, they planted an orchard of fruit trees along our fence line. Later that year, the remaining squirrels reproduced and had 7 babies. 2 additional families moved in bringing 9 more squirrels by winter. The winter was harsh this year, so 3 baby squirrels did not survive.

In the example above, the observer counted the number of squirrels living in their backyard. What method did they use to determine population size?

• direct observation

• indirect observation

• mark and recapture

• sample

The study of how things interact with each other and with their environment is called.
