Keystone species are species whose roles have a large effect on the types and abundance of other species in an ecosystem. Keystone species are important in the ecosystem as they help to determine the whole ecosystem and without them, the ecosystem would be different or stop to be in existence. Almost all animals that have a significant impact on the food webs are examples of keystone species.

The relationship between catabolism and anabolism is most similar to the relationship between which of the following pairs of te
MrMuchimi

Answer:

The pair of terms whose relationship is very similar to the relationship between catabolism and anabolism are exergonic and endergonic.

Explanation:

Anabolism and catabolism are processes that occur in matabolism, whose result is different.

  • <u><em>Anabolism </em></u><em>involves all the processes of manufacture or synthesis, in which chemicals are bound together to form new compounds. This process consumes energy, so it is called </em><em>endergonic</em><em>. </em>
  • <u><em>Catabolism</em></u><em>, unlike anabolism, is the process of degradation of complex molecules into simple molecules. One of the results of catabolism is the release of energy, which is equivalent to saying that it is an </em><em>exergonic</em><em> process. </em>

Relating catabolism to anabolism is similar to relating exergonics to endergonics.

  <em>  The other terms do not represent a similarity with the relationship between the processes of catabolism and anabolism.</em>
