Answer:
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).

Hope this helps
Explanation:
In an ocean ecosystem, many types of fish and turtles are herbivores that eat algae and seagrass. Sea urchins are powerful primary consumers in kelp forests.
Answer:
B- homology
Explanation:
If you look at the definition of homology, you can see that it compares the two organisms to see what is similar about them.
After a caterpillar eats a leaf, it can convert the chemical energy into mechanical energy to help it build a cocoon.
Answer:
Ichthyosaurs lived from Triassic to Middle Cretaceous approximately 250 million years ago until 110 million years ago
Explanation:
Ichthyosaurs evolved during the early Triassic period from land reptiles. This group was characterized by a spindle-shaped body, a shoulder girdle connected to a streamlined skull, two pairs of limbs, and digit-like bones. Moreover, Ichthyosaurs drew oxygen from the atmosphere (i.e., like marine mammals). Utatsusaurus is the oldest known Ichthyosaur species and it lived during the Lower Triassic. ln the same way to the land reptiles, Utatsusaurus had a pelvic girdle attached to the spine, and an equal length between the humerus and femur.
