There are three main types of galaxies<span>: Elliptical, Spiral, and Irregular. Two of these three </span>types<span> are further divided and classified into a system that is now known the tuning fork diagram. When Hubble first created this diagram, he believed that this was an evolutionary sequence as well as a classification.</span>
Answer: Here are three reasons if they don't help just tell me.
1. Changes in water temperature can affect the environments where fish, shellfish, and other marine species live. As climate change causes the oceans to become warmer year-round, populations of some species may adapt by shifting toward cooler areas. Oceans are becoming more acidic. 2. Oceans are becoming more acidic. The acidity of seawater is increasing as a direct result of increasing carbon dioxide levels in the air from human activities, like burning fossil fuels. Concentrations of carbon dioxide are higher than in the last 800,000 years. Carbon dioxide dissolves in water, changing seawater chemistry and decreasing pH (making seawater more acidic). The ocean’s increased acidity results in thinner shells and more shellfish die as they become easier for predators to eat. 3. More severe storms and precipitation can pollute coastal waters. Warmer oceans increase the amount of water that evaporates into the air. When more moisture-laden air moves over land or converges into a storm system, it can produce more intense precipitation—for example, heavier rainstorms. Heavy rain in coastal areas can lead to increases in runoff and flooding, impairing water quality as pollutants on land wash into water bodies. Some coastal areas, such as the Gulf of Mexico and the Chesapeake Bay, are already experiencing “dead zones” – areas where water is depleted of oxygen because of pollution from agricultural fertilizers, delivered by runoff. The phrase “dead zone” comes from the lack of life – including fish – in these waters.

Explanation:
Answer:
Biodiversity is very essential to the health of an ecosystem.
Explanation:
Biodiversity is essential to the health of an ecosystem because biodiversity provides functioning ecosystems that provides oxygen, clean air, clean water, pollination of plants, pest control, wastewater treatment and many ecosystem services. The change of temperature of the environment greatly affect the organisms because the organisms needs specific environment for growth and development. Habitat change, climate change, invasive species, overexploitation, and pollution are the factors that affect biodiversity. These factors causes increase or decrease in the biodiversity of the ecosystem.
