The answer is <span>a. most living organisms can survive in environments with several different temperature and salinity levels.
</span>Aquatic plants and animals depend on dissolved oxygen for respiration. The other abiotic factors that impact their life in an aquatic ecosystem are temperature, salinity, and flow and they determine the quality of their life. <u>It is not true that most living organisms can survive in environments with several different temperature and salinity levels.</u> On the contrary, a few species can live in <span>environments with several different temperature and salinity levels, for example, some bacteria. The most organism can survive in a specific range of abiotic factors.</span>
Answer: Protozoa contaminate the water supply.
Some protozoa are parasites and cause diseases like malaria.
Protozoa have an important role in the food chain.
Protozoa are parasitic or free living single celled eukaryotic organisms. They are mostly found in water bodies.
Protozoa contaminate the water supply: Some of the protozoan species which are released from the human feces usually contaminate thee water, and causes waterborne infections in humans. Examples are Cryptosporium and Giardia. The infection occurs through drinking water or swallowing water from swimming pool.
Some protozoa are parasites and cause diseases like malaria: The Plasmodium is the genus belonging to the protozoan parasites. This malarial parasite is transmitted by female Anopheles mosquitoes to humans. The parasite multiply in the red blood cells causes symptoms like fever, anemia, flue, illness and may also cause coma and death.
Protozoa have an important role in the food chain: The protozoa species plays many roles in the food chain, they act as consumers, predators or prey, herbivores and decomposers. Their main function is to control the population of other species in the same habitat. They engulf small single celled bacteria, hence prevents excessive bacterial colonization act as predator. They also feed upon the algal species therefore, act as herbivores. They act as decomposers, as they feed upon the organic matter present in the bottom of the aquatic water body. They are the source of food for large worm and insect species.
Answer:
3. Anatomy.
Explanation:
Anatomy is a branch of science which studies the physical structure of humans, animals, and other living beings. Anatomy is a part of biological studies. This field in the science is focussed on the shape, structure, and the relationship relevant to the living organisms.
Anatomy is further divided into two branches, namely, microscopic anatomy and macroscopic anatomy.
Therefore, the correct answer is option 3.
The products of photosynthesis is to gain energy and build compounds, like glucose from carbon dioxide, making it anabolic
The reactants of cellular respiration are catabolic, and that refers to the breaking down of compounds, which releases energy.
The relationship is that they're complex compounds that consist of materials coming from essential processes in the cell.
