Well, both have no skeletal or exoskeletal system and steal nutrients from their hosts. A leech though, usually steals nutrients from latching onto a host and stealing nutrients and such through blood. A tapeworm is accidentally ingested and lives in the stomach of its host, stealing the nutrients from the food the host eats. Hope this helps!

Consider the following pairs of organisms: large predators and small predators; large herbivores and small herbivores; and migra

Nastasia [14]

Answer:

Non-migratory animals and small herbivores

Explanation:

Habitat fragmentation is the process by which a previously continuous stretch of land becomes fragmented into smaller patches that are separated, causing the environment to be broken up, and to become discontinuous. For example, humans chopping down patches of trees in forests.

Animals that cannot freely move around (non-migratory mammals) will be most affected by this since they cannot simply move between the isolated pieces of land. Smaller herbivores will also be affected, because they generally do not freely move around and cover large spaces like large herbivores or predators.
