(a) Aquatic ecosystems are rich in diversity. The life inside water is largely influenced by various abiotic factors. The abiotic factors are the chemical and physical components of an environment that affect the organisms living there. The primary abiotic factors that affect the life underwater are temperature, light and availability of oxygen.
(b) Oxygen available to the aquatic organisms is a detrimental factor. If less oxygen is available underwater aquatic animals will not be able to respire and die.
Light is also an important abiotic factor for underwater organisms especially for the aquatic plants. the aquatic plants underwater will not be able to make their food by photosynthesis if proper light is not available.
Temperature also plays an important role. Too low or too high temperature affects the metabolic activities of the organisms.
Depth of water body affects the availability of light and oxygen to the aquatic organisms. Shallow water bodies have light available to more aquatic organisms.
Microbes were the first inhabitants of Earth. They are single-celled organisms, like bacteria, fungi, and protozoa. Microbes are still found just about everywhere today, thriving in boiling hot thermal springs
Hope this Helps :D
Answer:
Here is some background information...
Explanation:
Leeuwenhoek (1633-1723) used melted glass balls to form lenses for apparently crude simple microscopes that nevertheless magnified up to 275 times! Modern tests have concluded that he could have achieved a resolution of two micrometres.
The active site of an enzyme would form enzyme-substrate complex thus lowering the activation energy of the reaction and high rate of reaction is found.
Explanation:
The energy required to start the reaction is activation energy. In our system enzymes catalyses the reaction by lowering the activation energy. When the substrate binds to the active site or catalytic site of enzyme, an enzyme- substrate complex is formed. This complex reduces the time required for substrate changing into product. The enzyme substrate complex results in the conformational changes and contributes in lowering of activation energy.
Answer: Healthy.
Explanation:
An environment is said to be healthy when it has all the components such as parks, forests, houses, trees, schools contribute favorably to the people that living the environment.
Human beings needs food, shelter and better quality of life. These are the basic needs of human beings and hen it is full filled it means that they are having a healthy environment to live in.
