Mortality, or death rate is a measure of the number of deaths in a particular population, scaled to the size of that population, per unit of the time. In this case a factor that would result to an increased mortality rate in a population due to increased competition of water will be the density-dependent factor. 
        
             
        
        
        
Answer:
- Protozoans → would not have survived because they have no way to produce their own food → Heterotrophs
- Algae → would have survived without this food source → Heterotrophs
Explanation:
The protist kingdom is composed of two main groups.  The principal difference between them is that algae can produce their own food, while protozoans need to ingest other organisms or organic molecules to survive. 
- Algaes are autotroph 
- Protozoans are heterotroph 
<u>Protozoans</u>:
Microscopic unicellular organisms, eukaryotic and heterotrophs -predators or detritivores-. Most of them are aquatic free-living organisms, but some species are parasites. They feed on<u> bacteria</u>, other organic wastes, and other microscopic organisms. The phagocytosis process is normally used to ingest the food, invaginating their cell membrane.  
<u>Algae</u>:
Eukaryotic micro- or macroscopic organisms. Autotroph and photosynthetic. They might be either unicellular or pluricellular. They use sunlight to synthesize organic matter from water, CO₂, and mineral salts. Unicellular ones can be free-living or associate with others to form colonies. They are part of the phytoplankton and are ingested by heterotrophic organisms. Pluricellular algae do not create real tissues but they compose a tale. The depth at which they inhabit depends on the pigments they produce. All of them inhabit fresh or sea waters. 
 
        
             
        
        
        
Answer: Cerebrum 
Explanation:
The primary sensory areas of the cerebral cortex receives and processes the somatosensory, visual, olfactory and gustatory information.
Then along with the cortical areas, the brain regions synthesize the sensory information into the perfections of the world.
It is the largest section of the brain which lies in the front or the top of the brain stem.
It is one of the five major divisions of the brain which is most developed.

Answer: The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes
