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?

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

d. cellulose and starch

the correct answer was location c, because earth is tilted away from the sun at this time
