Question

1. students observed some turtles at a pond. the observations are listed below.

which of the observations describes a turtle interacting with an abiotic factor in its ecosystem?

1. a turtle holds out its legs to absorb more warmth from the sun.
2. a turtle is eating a snail.
3. a turtle basks on a rock.
4. a turtle soaks in a muddy puddle.

a. observations 2 and 3 only
b. observation 2 only
c. observations 1 and 4 only
d. observations 1, 3, and 4 only

Explanation:

Abiotic factors are non - living components of an ecosystem. The Sun (in observation 1), rock (in observation 3), and muddy puddle (in observation 4) are abiotic. A snail (in observation 2) is a biotic (living) factor. So we need to check which options include only the observations with abiotic interactions.

Answer:

D. Observations 1, 3, and 4 only
