The killer whales primarily feed on the secondary consumers in the oceanic food web.
Explanation:
Killer whales are the tertiary consumers and occupy the highest position in the ocean food web. They are predating carnivores and feed on secondary consumers like other fishes, marine animals like leopard seals, sea turtles, dolphins, sea birds, etc. These secondary consumers in turn feed on primary consumers like zooplanktons, small fishes etc which feed on the primary producers like phytoplanktons. The energy flow is highest at the primary producer level and decreases as it goes up to the consumer levels.
The answer is "<span>c. Ozone in the troposphere is beneficial to living organisms."
because options a, b and d are true about ozone layer.
</span>
Ozone layer is the area of the upper atmosphere, between around 15 and 35 km over Earth's surface, containing generally high groupings of ozone particles (O₃). Roughly 90 percent of the environment's ozone happens in the stratosphere. The ozone layer successfully squares all sun oriented radiation of wavelengths under 290nm from achieving Earth's surface, including certain kinds of UV and different types of radiation that could harm or kill most living things.

This is the respiration process, the reverse of photosynthesis.
