(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.

Most of the increase in global temperatures since 1950 has been caused by human activity.
The United States is the second largest contributor to carbon dioxide (CO2) in our atmosphere
As global temperatures increase, our societies will find it harder to adapt to the changes this brings, and some species are more likely to go extinct
The concentration of carbon dioxide (CO2) in our atmosphere, as of May 2020, is the highest it has been in human history.
NASA data show that average global temperatures in 2019 were 1.8 degrees F (0.98 degrees C) warmer than the 20th century average. In fact, the five warmest years in the 1880–2019 record have all occurred since 2015
Global warming puts coral reefs in danger as the ocean warms, scientist fear that coral reefs will not be able to adapt quickly enough to the resulting changing conditions, and bleaching incidents and diseases will increase
Answer:
B. Enough trees to create a close canopy.
Explanation:
Forests may have several tree species but one very important feature of forests is their close canopy of dense trees, often arranged in several strata (or layers).
It is what makes plant stems, leaves, and branches so strong.
