Fantom [35]

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.

These are physical features shared by organisms with common ancestry; they may have the same structure. What are these strucrure
alekssr [168]

Answer:

The correct answer will be- homologous structures

Explanation:

The history of how life has survived on the earth can be studied through a field of biology called evolutionary biology.

Studying the anatomical features of the organisms and the collected specimens (fossils) shows that some organisms posses similar anatomical structures which could be performing different functions.

The structures in organisms which are similar in their structure are thought to have derived from a common ancestor and are known as "homologous structures. "

Thus, homologous structures are the correct answer.
