As energy is transferred through an ecosystem, not all trophic levels receive the same amount. The marine ecosystem consists of primary producers like phytoplanktons; primary consumers like zooplanktons, krill; secondary consumers like leopard seals; and tertiary consumers like killer whales.
Explanation:
In an oceanic or marine ecosystem, the leopard seals are secondary consumers. They basically feed on the primary consumers. They are eaten up by the tertiary consumers. The prey animals of leopard seal includes primary consumers like small fishes, zooplanktons, coral polyps, krill etc. The energy level in the food web increases in a top to down pattern. The producers which occupy the base level will be with high energy and going up the food web, the energy will decrease subsequently. Leopard seals are huge and eat
