Answer:
Euglena is a single celled organism. It belongs to Kingdom Protista. Euglena is a eukaryotic organism that exhibit characteristics of both plants and animals. Some species of Euglena are photoautotrophs like plants which means they have ability to trap sunlight to produce food by the process of photosynthesis. Whereas, some species are heterotrophs like animals which means they obtain food by feeding on other organisms.
If scientists remove all of the chloroplasts from a Euglena, it will not be able to perform photosynthesis because chloroplast is an organelle that contains light sensitive pigments named as chlorophyll. Chlorophyll traps light energy from sun. Sunlight energy, along with carbon dioxide and water produces food in the form of glucose in plants and other photoautotrophs.
I Believe The Answer Is B. Physical Weathering.
All living creatures are classified into systems and sub-systems based on their similar characteristics. They are divided from bigger groups into smaller groups based on the detail of their similarities i.e. how they look, move, reproduce and how they relate to each other. A practical way of understanding the classification of living organisms is that organisms are linked to other similar organisms via family trees. The classification of all living creatures includes at least four levels: order, families, genus and species.
