A) Apex predators require a large biome to meet their food/energy demands. In this exercise, we will examine how large of a spatial area of ocean is needed to sustain one Bottlenose dolphin. A typical adult Bottlenose dolphin will consume 17 kilograms of fish per day. If there are approximately 960,000 joules (j) of energy in 0.12 kilograms of fish, how many joules of energy does the dolphin consumer per day?

B) Now let's consider how much zooplankton that was required to feed the 17 kilograms of fish eaten by the one Bottlenose dolphin in one day. Let's assume 10% ecological efficiency when fish eat zooplankton. How many joules of energy from zooplankton was used to grow the 17 kilograms of fish consumed by the dolphin?

C) Similarly, let's assume 10% ecological efficiency for zooplankton to consume phytoplankton (algae). How many joules of energy from phytoplankton was used to grow the 17 kilograms of fish consumed by the dolphin?

D) Let's assume that there is 400 grams of phytoplankton in one square meter of water in the southern Atlantic ocean and there is 100,000 joules of energy in 30 grams of phytoplankton. How many hectares (1 hectare = 10,000 m2) of ocean does it take to sustain one Bottlenose dolphin for one day?
