Which of the following choices correctly shows the way energy
flows in an ecosystem?
A. Seaweed to Fish to Seal to Polar
Bear to Bacteria
B. Polar Bear to Seal to Fish to
Seaweed to Bacteria
C. Bacteria to Seaweed to Fish to Seal
to Polar Bear
D. Seaweed to Bacteria to Seal to Fish
to Polar Bear

C. Bacteria to Seaweed to Fish to Seal to Polar Bear

Explanation:

Every ecosystem consists of multiple organisms. These organisms feed on each other, forming a food chain. The energy within an ecosystem flows through the food chain.

Here, we're supposed to determine which food chain is the correct one. All organisms can be divided into producers and consumers. Producers are organisms that produce their own food, while consumers feed by consuming other organisms.

The only food chain that makes sense is shown in option C. I wouldn't say that bacteria belong to it as the seaweed is an example of a producer. It doesn't consume other organisms. But, fish feed on it, then seals eat the fish, and polar bears eat the seals. This is why we can safely say that option C is the correct one, despite bacteria being present there. Any other combination wouldn't work as, for example, bacteria (A) and seals (B) can't eat polar bears and the fish can't eat seals (D).

d. in sexual reproduction, offspring have more chromosomes than

either parent.

asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). sexual reproduction produces a random mixture of the genetics derived from both parents
