Answer:
A snail eats a clam.
Explanation:
Interactions always occur between organisms in an ecosystem. An interaction between two organisms is called SYMBIOSIS. Symbiosis consists other types which includes PREDATION. Predation is a kind of symbiotic relationship between two organisms in which one kills and feeds on the other in order to obtain energy. The organism that kills is called the PREDATOR while the organism that is killed is called PREY.
In this example, a snail feeding on a clam best represents the example because the snail (PREDATOR) is obtaining energy by killing the clam (PREY). In other options, no organism is killed.
Answer:
D
Explanation:
This is because a bad ratio would be one where the volume is larger than the surface area. Once a cell's volume is larger than the surface area, there's not enough surface area to process all the products coming in and waste coming out. Ideally, you'd want a surface area and volume to be as close to each other as possible in number, but you'd rather have the volume be less than the surface area.

They are like the animals who fly. They do have built-in mechanisms that enable them to go up and down in the water. The downward pull is the gravity and the upward push of the buoyancy. The force of the buoyancy is equal to the weight of the fluid displaced by that object. So fishes use their swim bladder for them to be able to ascend.
