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:
B. There is less biodiversity in the high tide zone because the tidal changes make survival difficult.
Explanation:
The high tide and low tide zones are located on the seashore as the ocean water merges with land.
High tide zones are usually covered with water during high ocean tide while low tide zones are always submerged in water.
There is low biodiversity in the high tide zone because the tide here changes rapidly and organisms find it difficult to adapt. Organisms that inhabit here must be welll adapted to withstand peroids of high tides.
The answer is “b” because the prefix “geo” means “relating to the earth”
