Answer:
All euglena have chloroplasts and can make their own food by photosynthesis. ... Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water.
Explanation:
In general, flagellum is a long whip like organ which protrudes to the exterior from the cell body and permits mechanical work without any marked change in the form of the effector cell. In Euglena, there are two flagella. One of them is equal in length to body while other is short.

Definitely decompose dead organisms, otherwise there would be no oil for us.
<span>Genetic variation can be caused by mutation (which can
create entirely new alleles in a population), random mating, random
fertilization, and recombination between homologous chromosomes during
meiosis (which reshuffles alleles within an organism's offspring)</span>
The key processes in the fast carbon cycle include: Photosynthesis: the absorption of CO2 from the atmosphere (terrestrial plants) and from oceans (marine plants) to produce organic carbon structures. Respiration: the release of CO2 into the atmosphere, soil and oceans by animals as they exhale.
