Answer:
a. Competition between purple and orange woozles might have been responsible for where you found them on the island.
Explanation:
The competitive exclusion principle establishes that two or more species that share the same niche requirements and are in biological competition for the same resources won´t be able to coexist indefinitely in the same space if the other ecological factors are constant. When the superior competitor occupies the inferior competitor´s fundamental niche, the first species has advantages over the second species and monopolizes all the resources. From that moment, the inferior species is displaced and must adapt to use other resources changing its behavior, or must migrate to another area where it can get access to its needs or get extinct.
The fundamental niche of the orange woozles includes the ground and the top of the trees. But they were probably displaced by the purple woozles that was the superior competitor and occupied part of the fundamental niche of the orange woozles.
There are 3 types of muscle tissue ; skeletal, smooth and cardiac. The muscle fibres of cardiac tissues are striated and branched. They have many nuclei. They make up the tissues of the walls of the heart. The smooth muscle cells/fibres are spindle shaped and compose the inner walls of lumens such as the Gastro Intenstinal Tract. The cells have one central nuclei. Skeletal muscle fibres are striated (but not branched) and make up muscle tissue that attach to the skeleton.
