I believe the correct answer is A. Irtysh
Answer:
The correct answer is - plankton, Fish, krill, whales.
Explanation:
In the Antarctic ecosystem, different kinds of organisms present that can be understood by the food web available there. The food web is very complex in the Antarctic ecosystem. Phytoplanktons are producers in this food web and krill are primary consumers.
Krills are important animals of this ecosystem as most of the secondary consumers including fishes, baleen whales, penguins, and seals and many birds are feeding on krill. The various species eat fish, penguins, squid, and krill.
1. Supplementary angles : Two angles are supplementary if their sum is 180°.
For angle 1 and ∠COF to be supplementary,
∠1 + ∠COF =180°
must be satisfied.
We see in the figure that angle 1 and COF form a straight line.
The angle of a straight line is 180°.
∴ 1 is a supplement of ∠COF.
Answer : YES
2. Given : ∠COF =150° ;
AD is perpendicular to BF.
Here, ∠BOC + ∠COF = 180° , since they form a straight line.
∠BOC = 180° - ∠COF = 180° - 150° =30°
∴ ∠BOC = 30°
Answer : D. 30°
