1. Read the following scenario: In a pond, the primary producer is a green algae, Spirogyra; the primary consumer is the crustacean
Daphnia; the secondary consumer is a small fish, the bluegill; the tertiary consumer is a larger fish, the
smallmouth bass.
What changes can be expected in the pond if the Daphnia are killed with pesticides?

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves

it is a limiting nutrient limited by a single nutrient in the ecosystem, & the single goes very slow.

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
