Multi cellular organisms are composed of many cells whereas unicellular organisms are composed of single cell. Multicellularity is indeed a progressive attribute of evolution where cells form tissue which forms organ and then organ system and finally an organism. Both multi cellular and unicellular organisms has advantages and disadvantages of their own. One of the main disadvantage of multi cellular organisms is that due to such a complex composition and functioning they require a large amount of energy for their maintenance and survival. Different organs and system require a huge amount of energy when it comes to comparison with unicellular organisms. A large amount of energy is also wasted in all these life processes. Though multi cellular organisms can survive in a variety of environmental conditions but then also their survival is difficult than any unicellular organism.
Answer:
Due to different grouping style
Explanation:
There are two modes of classifying an organism due to which two different cladogram are produced-
A) When the organisms are grouped together on the basis of similarities shared by them – Such species are named based on the name of older species and the newly discovered species sharing similar traits are kept under older species thereby dropping its own name.
B) In the second method, the minute differences are observed in species to group them into several branches arising from one parent organism.
