Answer:
temperature, water quality and sunlight.
krill, small crustaceans, and zooplankton
Step-by-step explanation:
Biotic factors such as krill, small crustaceans, and zooplankton and abiotic factors such as temperature, water quality and sunlight has a direct effect on the growth and distribution of whales and seals. Due to change in climate, temperature of the earth changes which destroy the natural habitat of many species. Krill, small crustaceans, and zooplankton are food of the whales which are migrated from their natural habitat so whales also moves to those areas where their food is available. Sunlight is also needed by the whales and seals but due to ozone depletion, UV radiation injured the skin of both whales and seals. Poor water quality also adversely affected the health of whales and seals.
