Please help with this question I need it fast

Explanation:

In 1A, the producer is the grass, the primary consumer is the sheep, and the secondary consumer is the human. Producers make their own energy source (hence the name). In this situation, grass (and other autotrophs) are able to produce their own food through photosynthesis. The sheep is considered a primary consumer, since it is the first to interact with the energy produced by the grass in terms of the food chain. On a similar logic, the human is the secondary consumer as it gets its energy from the sheep and not directly from the grass.

We can apply the same logic for question 1B. The phytoplankton makes its own food, therefore qualifying as a producer. Prawns consume the plankton, so that makes them a primary consumer. Again, in terms of the food chain, the prawns get their energy from the producers directly. Tuna are secondary consumer since they get their energy from the prawn and not directly from the plankton.
